Output Console

The term 'output console' can refer to multiple things. Generally, it refers to the actual zscript debugger console that can be opened in ZC via "ZC -> Show ZScript Debugger"; though it could also refer to the general log output, which is logged to "allegro.log". Errors and debug information are logged to the Output Console (some of which is only logged if certain quest rules are enabled), which the user can use to debug their scripts. Logging Functions can be used to directly output to the console.

Message Strings

Edited in 'Quest->Strings' in ZQuest, message strings represent messages that can be displayed on-screen to the player, including not only text, but also various formatting options, and String Control Codes. ZScript can use messagedata pointers to modify message strings directly.

String Control Codes

vRev April 16th, 2023 for 2.55 A114 Special effects can be created when message strings are displayed by inserting special control codes into the string. All valid codes are listed below.

Formatting Codes

These codes have formatting effects on the string being displayed, such as changing the font, text color, or inserting characters or tiles into the message.

Menu Codes

These codes relate to popping up a menu for the player to select a choice from.

Switch Codes

These codes change from the current string immediately to a different string. If you attempt to switch to a string that does not exist, it will instead act as though you switched to a string that is entirely empty.

Counter Mod Codes

These codes all center around modifying counter values.

Misc Codes

Quest Rules

Quest Rules are global settings configurable in ZQuest. Scripts can read and modify these settings using Game->FFRules. To find a QR by name, go to Quest->Options->Search QRs in ZQuest.

TODO: Add IC_ constant infopage

Global Pointers have a single global instance which can be referenced anywhere.

Data Pointers must be loaded before they can be used. Each has its' own pointer type of which variables can be declared.

Sprite objects are a subset of object types which share a variety of attributes. These include weapons, npcs, items, etc.

Managed Pointers all have a total maximum that can be in use at a time, and are only freed for re-use using Free() and Own() functions.

WebSocket Pointers

websocket websocket pointers allow for communicating with a WebSocket server to send and receive messages. Here is an example of using a websocket: #include "std.zh" generic script WebSocketScript { void run() { printf("Connecting to websocket.\n"); websocket ws = Game->LoadWebSocket("ws://ws.ifelse.io"); ws->Own(); bool hasSentMessage = false; while (true) { if (ws->State == WEBSOCKET_STATE_CONNECTING) { Waitframe(); continue; } else if (ws->State == WEBSOCKET_STATE_CLOSED) { char32 error[0]; ws->GetError(error); printf("Failed to connect: %s\n", error); break; } if (ws->State != WEBSOCKET_STATE_OPEN) { printf("Failed to connect: %l\n", ws->State); break; } if (!hasSentMessage) { printf("Connected!\n"); ws->Send("hello world!"); ws->Send("domo arigato!", WEBSOCKET_MESSAGE_TYPE_BINARY); hasSentMessage = true; } while (ws->HasMessage) { int message_ptr = ws->Receive(); int type = ws->MessageType; if (type == WEBSOCKET_MESSAGE_TYPE_TEXT) printf("got text message: %s\n", message_ptr); else if (type == WEBSOCKET_MESSAGE_TYPE_BINARY) { int len = SizeOfArray(message_ptr); printf("got binary message of length: %d\n", len); for (int i = 0; i < len; ++i) printf("%d: %l\n", i, message_ptr[i]); } else printf("got message, but with unknown type: %l\n", type); } Waitframe(); } } }

Portal Pointers

portal portal pointers allow accessing the on-screen 'portals', objects which warp the player to a specific destination when touched. Portals can be saved if they are created from a savedportal object, in which case they will be re-created every time the screen is entered until they are used. See: LoadPortal, savedportal->Generate

int X; int Y;

The portal's X/Y position.

int AFrame

Which frame of the portal's animation is currently showing. Add this to the OriginalTile to get the current tile.

int OriginalTile;

The starting tile of the portal's animation.

int ASpeed;

The duration, in frames, that each tile shows for.

int AClk;

The animation clock used for the portal's animation timing. The tile advances when this reaches the ASpeed.

int Frames;

The total number of tiles in the portal's animation.

void UseSprite(int sprite);

Set the graphics of the portal to a sprite data sprite.

int DMap; int Screen;

The destination of the warp. (The portal's X/Y doubles as the destination X/Y).

int WarpSFX;

The SFX to play when warping.

int WarpEffect;

The warp effect to use for the warp. Use the WARPEFFECT_Values representing various warp transition effects.

0. WARPEFFECT_NONE
1. WARPEFFECT_ZAP
2. WARPEFFECT_WAVE
3. WARPEFFECT_INSTANT
4. WARPEFFECT_OPENWIPE

constants.

bool CloseDisabled;

If the portal is disabled due to the player being too close after entering the screen. If true, the portal will not warp the player. Automatically becomes false if the player is not touching the portal.

savedportal SavedPortal;

The savedportal object linked to this portal, if one exists. NULL otherwise. (Read/Write)

void Remove();

Deletes the portal outright. Does NOT affect a linked savedportal, that would need to be deleted separately.

SavedPortal Pointers

savedportal savedportal pointers allow accessing all portals currently active in a quest, which are saved to the save file. See: LoadSavedPortal, portal

int X; int Y;

The portal's X/Y position.

int SrcDMap; int SrcScreen;

The dmap/screen that the portal spawns on.

int Sprite;

The sprite data sprite used for the portal's graphics.

int DestDMap; int DestScreen;

The destination of the warp. (The portal's X/Y doubles as the destination X/Y).

2. WARPEFFECT_WAVE
3. WARPEFFECT_INSTANT
4. WARPEFFECT_OPENWIPE

constants.

portal Portal;

The portal object linked to this savedportal, if one exists. NULL otherwise. (Read/Write)

void Remove();

Deletes the savedportal outright. Does NOT affect a linked portal, that would need to be deleted separately.

portal Generate();

If a portal object is already linked, returns it. Otherwise, if the current DMap matches the portal's SrcDMap AND the current Screen matches the portal's SrcScreen, creates a new portal object using this savedportal's data, and returns that. Otherwise, returns NULL.

This section is dedicated to the underlying mechanics of ZScript. This section will cover everything from the basics of if, else, while, for, etc all the way up to class, namespace, etc. TODO: Under construction!

Operators

This section contains information on the various operators that can be used in expressions in ZScript.

Addition +

ex. 2 + 2 gives 4

Subtraction -

ex. 10 - 5 gives 5

Multiplication *

ex. 5 * 7 gives 35

Division /

ex. 7 / 2 gives 3.5 Division truncates everything beyond 4 decimal places.

Modulo %

Modular division, gives the remainder of a division ex. 10 % 3 gives 1, 5 % 3 gives 2, 16 % 2 gives 0, 5.5 % 3 gives 2.5

Power/Exponentiation ^^^

Behaves differently if the long type is involved. ex. 5 ^^^ 2 gives 25, 5L ^^^ 2L gives 25L

Assignment Operators

With a variable (x in this example), you can use some assignment operators.

• x = 5;, sets the value of variable x to 5
• x += 5; same as x = x + 5;
• x -= 5; same as x = x - 5;
• x *= 5; same as x = x * 5;
• x /= 5; same as x = x / 5;
• x %= 5; same as x = x % 5;

Increment Operators

++x, x++ are the same as x = x + 1, and --x, x-- are the same as x = x - 1. With one small exception, which rarely matters. If you use these in an expression, the expression value is different. Example: x = 5; y = ++x; //y is 6, x is 6 x = 5; y = x++; //y is 5, x is 6 If you are NOT using it in an expression, it is best to use the pre- version (++x or --x), such as in for loops for(int q = 0; q < 10; ++q).

Keywords

This section contains information on the various keywords that can be used in ZScript, and that may appear in this documentation.

constexpr

Currently, only internal functions can be constexpr. When a constexpr function is called and all of the parameters of the call are constant at compile-time, the compiler will run the constexpr function at compile-time. Such function calls can be used in places that require compile-time constant values.

static

Functions in a class may be declared as static. This effectively removes them from objects, making them a 'global function' in the class's name. So, static functions can only be called either from within the class directly, or by using 'classname.funcname()', but not from an arrow. Also noteworthy is that static functions do not have access to the class's 'this' pointer.

The Debug-> pointer holds some internal debug variables. You probably won't need to use it.

bool MoveXY(float dx, float dy, int special); bool CanMoveXY(float dx, float dy, int special);

Attempts to move the enemy by 'dx' in the x direction and 'dy' in the y direction, failing if it is blocked by something it cannot walk through. Use the 'SPW_' constants for 'int special'; i.e. 'SPW_FLOATER' to indicate a flying enemy. Returns true if the enemy moves the full distance, false if the enemy was blocked at all. The 'CanMoveXY' variant will not actually move the enemy at all, but will run the collision checks and return true if it CAN move the full distance, or false if it WOULD be blocked.

bool Move(int dir, float pxamnt, int special); bool CanMove(int dir, float pxamnt, int special);

Attempts to move the enemy by 'pxamnt' pixels in the 'dir' direction, failing if it is blocked by something it cannot walk through. Use the 'SPW_' constants for 'int special'; i.e. 'SPW_FLOATER' to indicate a flying enemy. Returns true if the enemy moves the full distance, false if the enemy was blocked at all. The 'CanMove' variant will not actually move the enemy at all, but will run the collision checks and return true if it CAN move the full distance, or false if it WOULD be blocked.

bool MoveAtAngle(float degrees, float pxamnt, int special); bool CanMoveAtAngle(float degrees, float pxamnt, int special);

Attempts to move the enemy by 'pxamnt' pixels in the 'degrees' angle, failing if it is blocked by something it cannot walk through. Use the 'SPW_' constants for 'int special'; i.e. 'SPW_FLOATER' to indicate a flying enemy. Returns true if the enemy moves the full distance, false if the enemy was blocked at all. The 'CanMoveAtAngle' variant will not actually move the enemy at all, but will run the collision checks and return true if it CAN move the full distance, or false if it WOULD be blocked.

bool CanPlace(float dx, float dy, int special = SPW_NONEUse the 'SPW_' constants to provide a special value; i.e. 'SPW_FLOATER' for flying enemies. Use 'SPW_NONE' if you don't know what to use., bool knockback = falseSome enemies treat pits/liquid as solid, EXCEPT if they are being knocked back. 'bool knockback' here affects this for the placement checks., int nw = -1, int nh = -1If 'nw' or 'nh' are > -1, they will be used as the width/height of the enemy for the check. Otherwise, the enemy's hitwidth/hitheight are used. );

Returns true if the enemy could be arbitrarily placed at (ex. teleported to) the position 'nx,ny'.

bool MovePaused();

Returns true if the enemy is in a state in which it should not be allowed to move (ex. spawning, dying, stunned, time frozen by clock) Returns false otherwise.

bool Knockback(int time, int dir, int speed);

Attempt to knock back the npc in 'dir' direction, for 'time' frames, at a rate of 'speed' pixels per frame. Returns true if successful, false if the enemy could not be knocked back.

bool NoScriptKnockback;

bool NoSlide;

False by default. If set to 'true', engine knockback is ignored.

int SlideSpeed;

PalData Pointers

paldata paldata pointers allow storing and modifying various palettes. A paldata holds 256 rgb colors divided into 16 CSets. Colors can be disabled to mask them out of various operations. See: CreatePalData

The RGB Type

rgb rgb is a special type used by paldata for storing colors as a single integer. It has a range from 0x0L to 0x3F3F3FL with a special value of INVALID_COLOR (-1) for unassigned colors. rgb cannot inherently cast to other primitive types. See: CreateRGB

rgb Color[256];

Access colors of the paldata as rgb. Reading an invalid color will return INVALID_COLOR (-1). To write a color as invalid, use ClearColor() instead.

int R[256];

int G[256];

int B[256];

Access the R/G/B values of the paldata, ranging from 0-63. Reading an invalid color will return -1. To write a color as invalid, use ClearColor() instead.

void ClearColor(int index);

Clears the color at index on the paldata. Cleared colors will be skipped when writing to a palette.

void ClearCSet(int cset);

Clears an cset on the paldata. Cleared colors will be skipped when writing to a palette.

void ColorValid(int index);

Returns true if the color at index is valid.

void LoadBitmapPalette(int pal);

Loads the palette from an image. Currently only BMP, PCX, and TGA are supported.

void WriteLevelPalette(int pal);

Writes the paldata to a level palette. Empty color indices will be skipped.

void WriteLevelCSet(int pal, int cset);

Writes a cset of the paldata to a level palette. Empty color indices will be skipped.

void WriteSpritePalette(int pal);

Writes the paldata to a sprite palette page. Empty color indices will be skipped.

void WriteSpriteCSet(int pal, int cset);

Writes a cset of the paldata to a sprite palette page. Empty color indices will be skipped.

void WriteMainPalette();

void Mix(paldata start, paldata end, float percent = 0.5, int color_space = CSPACE_RGB);

Interpolates all the colors on a paldata between start and end. The value of percent should range from 0.0000-1.0000 with 0 representing the starting color. Color space specifies a color space to interpolate through, changing the resulting average.

void MixCSet(paldata start, paldata end, int cset, float percent = 0.5, int color_space = CSPACE_RGB);

Interpolates all the colors on a cset of a paldata between start and end. The value of percent should range from 0.0000-1.0000 with 0 representing the starting color. Color space specifies a color space to interpolate through, changing the resulting average. Color space specifies a color space to interpolate through, changing the resulting average. Use the following CSPACE_ constants:

0. CSPACE_RGB
1. CSPACE_CMYK
2. CSPACE_HSV
3. CSPACE_HSV_CW
4. CSPACE_HSV_CCW

genericdata LoadGenericData (int generic_script_id);

These functions load the specified pointer, returning NULL on a failure.

mapdata LoadMapData(int map, int screen);

Loads the mapdata pointer for the screen at (map,screen). Edits to these pointers do not persist through quest exit. Edits to these pointers will NOT affect the "current screen", even if the current map/screen is supplied; see LoadTempScreen() below for that.

mapdata LoadTempScreen(int layer);

Loads the temp mapdata pointer for the specified layer. LoadTempScreen(0) gives a pointer that works mostly the same as Screen->, while passing 1 through 6 will give equal access to the other layers of the screen. Modifications to these pointers are reset when the screen changes.

If "Old Args for CreateBitmap and bitmap->Create()"at "ZScript->Quest Script Settings->Instructions" is enabled, then width and height are swapped with each other.

bitmap AllocateBitmap();

Allocates a new bitmap pointer, but does not create a canvas on it. bitmap->Create() can later be used to create a canvas on the pointer. Be sure to Free() it when you are done, or Own() it to attach it to a script!

bitmap LoadBitmapID(int render_targetRT_ constants);

Loads a bitmap pointer for one of the old-style render target RT_ bitmaps. TODO: Unsure if these have been tested to work properly?

randgen LoadRNG();

Loads an unused randgen pointer. Be sure to Free() it when you are done, or Own() it to attach it to a script!

stack LoadStack();

Loads an unused stack pointer. Be sure to Free() it when you are done, or Own() it to attach it to a script!

, bool user_scaleIf true, the user's cursor scale config will be applied. = false);

Sets the custom cursor used by ZCM_CUSTOM from the bitmap b. fx,fy indicates the focal pointNormal cursors usually place this at the upper-left, on the transparent pixel the arrow points to. For a crosshair cursor, this would be the center point. of the cursor. WARNINGS: The palette will NOT update on custom cursors automatically. You must call this function again if the cursor should be affected by palette changes. The cursor will use the image on the bitmap at the START of the frame, before any of this frame's draws. This means you should have a Waitframe() after the draws to the bitmap, before calling this function.

int TrigGroups[256]; int TriggerGroups[256];

Read-only. The 256 'Trigger Group' values for the current screen. These represent a count of combos that 'Contribute to TrigGroup' that are present on the screen, layers, and ffcs.

Global Functions

Global functions are a member of no pointer type, and instead are simply able to be called from anywhere.

Functions that don't fit a particular category.

void Quit();

Exits the current script entirely. Has the same effect as reaching the end of 'void run()', or 'return'ing from the 'void run()'.

void QuitNoKill();

Exits the current script entirely, and forcibly skips the de-allocating of objects 'Owned' by the script. Only use this if you know what you are doing!

void Waitframe();

Yields the script to the engine for the current frame. The engine will proceed with one frame of gameplay before resuming this execution of this script.

void Waitdraw();

When called the first time in a frame, the script ends running for a portion of time. The engine will proceed with part of a frame of gameplay, allowing other engine activities to occur, before resuming this script. If called again, the additional call will act as a call to 'Waitframe()', as it cannot wait any more of the frame without the frame ending.

void WaitTo(int timing, bool at_least = false);

Can only be used in a passively-running Generic Script. Waits until it is the specified timing. If 'at_least == true', will not wait if it is already past that timing for the frame.

int WaitEvent();

Can only be used in a passively-running Generic Script. Is only used in conjunction with 'EventListen[]'. Waits until any event the script is listening to via EventListen[] = true occurs. When such an event occurs, the function will return the event type, and Game->EventData[] will be filled with information about the current event, much of which is modifiable.

void CopyTile(int src, int dest);

Copies tile 'src' to tile 'dest'.

void OverlayTile(int src, int dest); Since 2.53

Overlays tile 'src' over tile 'dest'.

void SwapTile(int a, int b);

Swaps the tiles 'a' and 'b'.

void ClearTile(int tile);

Clears the tile 'tile' to be blank.

Note

All tile modifications are temporary, and will be reset when the quest is exited.

float Distance(float x1, float y1, float x2, float y2);

float Distance(float x1, float y1, float x2, float y2, int scale);

Calculates the distance between two points, optionally using a scale divisor to handle distances that would otherwise overflow.

long LongDistance(long x1, long y1, long x2, long y2);

long LongDistance(long x1, long y1, long x2, long y2, long scale);

Same as 'Distance()', but takes distances as 'long' coordinates, returning a 'long' distance value.

void SaveSRAM(char32[] filename.zcsram, int flags);

void LoadSRAM(char32[] filename.zcsram, int flags);

Saves/loads internal data (which is normally temporarily altered by scripts) of the types specified in 'flags'. Flags:

• npcdata: 0x01
• itemdata: 0x02
• spritedata: 0x04
• combodata: 0x08
• dmapdata: 0x10
• mapdata: 0x20

Flags are OR'd together (ex. 0x01 | 0x02 | 0x04). Passing '0' will use ALL flags. Related: OnSaveLoadUnder Construction!, OnSaveUnder Construction!

void OwnObject([Object] obj);

Takes an ObjectUnder Construction! parameter. Grants ownership of the object to the currently running script. When the owning script dies, the owned object will be deleted. Note: Objects are already owned by the script that created them automatically, without needing to call this function.

void GlobalObject([Object] obj);

Takes an ObjectUnder Construction! parameter. Globalizes the object, making it no longer owned by any script. Globalized objects will be saved to the save file, and remain intact upon reloading. Calling 'OwnObject()' on a globalized object will undo this, returning it to script ownership.

These functions relate to various mathematical operations.

int LPow(long base, long exp);

Returns 'base^exp', with '0⁰==1'. Negative values of 'exp' work, though may not be useful, as the return value is truncated to the nearest long.

int InvPow(int base, int exp);

Returns 'base^(1/exp)', undefined if 'exp' is 0, or if 'exp' is even and 'base' is negative. Negative values of 'exp' work, though may not be useful, as the return value is truncated to the nearest integer.

float Sqrt(float val);

Returns the square root of the value. Undefined for negative values, and will return an error.

float Sin(float deg); float Cos(float deg); float Tan(float deg);

Returns the trig Sin/Cos/Tan of the degree value given.

float RadianSin(float rad); float RadianCos(float rad); float RadianTan(float rad);

These functions all relate to the Output Console, and printing data to it.

void Trace(untyped val); void Trace(long val);

Prints the passed value to the output console. Includes a newline character after the value. If a long val is passed, it prints the number with no decimal place (long format). Otherwise, it prints the number with 4 decimal places.

void TraceB(untyped val);

Prints the passed value to the output console, as "true" if the value is nonzero, or "false" if the value is 0. Includes a newline character after the value.

void TraceS(char32[] string);

Prints the passed string to the output console. Does not include a newline character after the string.

void TraceNL();

Prints a newline character to the output console.

void TraceToBase(int val, int base, int mindigits);

Prints the passed value to the output console, in the specified base, where "2 <= base <= 36". Value will be floored before print, so decimal values are not printed. Will print at least 'mindigits' digits, using leading 0s as needed. Includes a newline character after the value.

void ClearTrace();

Clears the logs from allegro.log, and clears the output console.

void printf(char32[] format_string, ...untyped argsTakes 0+ untyped args);

void printfa(char32[] format_string, untyped[] argsTakes an array of untyped args);

Prints the specified format_string to the output console, using the given args to fill in parts of the string that are specially marked. Does not include a newline character after the string. Valid patterns:

• '%i' or '%p': Inserts the value as an integer (no decimal places).
• '%f': Inserts the value as a float number (decimal places included)
• '%d': Acts as '%i' if all decimal places are '0', as '%f' otherwise.
• '%l': Inserts the value as a long (decimal places included, but no decimal point)
• '%s': Inserts the value as a string (must be a valid array pointer)
• '%c': Inserts the value as a character.
• '%x' or '%X': Inserts the value as a hexadecimal integer (no decimal places). Capitalization of letters matches the capitalization of the 'x'.
• '%b' or '%B': Inserts the value in Binary. 'b' has no decimal included, while 'B' uses all 32 bits as a long.
• '%a?': Inserts an array. Must be followed by another letter from this list, which will be used as the format for each element in the array. Ex: '%aB' inserts an array, where each index is inserted in long binary. '%04ad' inserts an array, where each element is a number of at least 4 digits.
• '%%': Inserts a single '%', does not act as a pattern.

Also, by including numbers between the '%' and letter for patterns (excluding '%s', '%c', '%%'), it will take a minimum of that many digits, adding leading 0's as needed. Example: '%5i' given a value of '253' would display as '00253', filling up 5 digits of space. The max number of digits is 10, except in Binary ('%b','%B'), where it is 32. Related: sprintf()

These functions relate to the manipulation of strings.

char32[] utol(char32[] string); char32[] ltou(char32[] string); char32[] convcase(char32[] string);

Compares the contents of the two strings. Returns '0' if the strings are equal. Otherwise, compares the first character that is different between the strings, returning >0 if it is larger in str1, and <0 if it is larger in str2. 'strncmp' and 'strnicmp' only compares the first 'num_chars' characters. 'stricmp' and 'strnicmp' compare case-insensitively.

int strchr(char32[] str, char32 c);

Returns the first index of 'str' that contains the character 'c'.

int strrchr(char32[] str, char32 c);

Returns the last index of 'str' that contains the character 'c'.

int strlen(char32[] str);

Returns the length of the string in characters.

int strcspn(char32[] str, char32[] chars);

Returns the length in 'str' until any character NOT in 'chars' is found. Related: strcspn

int itoa(char32[] dest, int val);

Converts the value 'val' to a string, and places it in the 'dest'. Ex. itoa(dest, 72); leaves the buffer holding "72".

int xtoa(char32[] dest, int val);

Converts the value 'val' to a string, as hexadecimal, and places it in the 'dest'. Ex. xtoa(dest, 21); leaves the buffer holding "0x15".

These functions relate to arrays.

void ArrayCopy(T[] dest, T[] src);

Copies all data from 'src' to 'dest'. If the arrays are not the same size, the smaller size is used, and the excess in the larger array is ignored.

bool IsValidArray(untyped[] arr);

Returns true if the value 'arr' points to a valid array.

int SizeOfArray(T[] arr);

Returns the size of the array

void ResizeArray(T[] arr, int size);

Resizes the array 'arr' to size 'size'. If 'size' is <1, the array becomes size 1 instead.

void OwnArray(T[] arr);

Grants ownership of the target array to the currently running script. If this array is not a local array, nothing happens. If it is a local array, the array will no longer be destroyed when it reaches the end of its' declaring scope- it will last until the owning script ends, at which point it will be freed.

void DestroyArray(untyped[] arr);

If 'arr' is a local array, destroys it immediately. Otherwise does nothing.

bool ArrayPushBack(T[] arr, T val); bool ArrayPushFront(T[] arr, T val); bool ArrayPushAt(T[] arr, T val, int indx);

Increases the size of the array by 1, inserting 'val' at the back/front/specified index of the array. If an invalid index is passed, the back of the array will be targetted. Returns false if it fails for any reason, such as the array being max-sized already.

T ArrayPopBack(T[] arr); T ArrayPopFront(T[] arr); T ArrayPopAt(T[] arr, int indx);

Decreases the size of the array by 1, removing and returning the element at the back/front/specified index of the array. If an invalid index is passed, the back of the array will be targetted. Errors and returns -1 if the array is size 0.

untyped Data[DataSize];

A misc data array, resizable by writing to DataSize (see above). All indexes are saved with the save file, including any resizing.

File Pointers

file file pointers allow directly interacting with files on the user's system. Each quest has a directory created at [zc root]/files/[quest name]/, and ONLY files within this directory are accessible. All paths are relative to this directory. There is no 'LoadFile' function. To load a file, declare a variable of type 'file', and call Open(), Create(), or OpenMode() to open a file to it. General info about filesystem access: Files opened with 'Open()' or 'Create()', as well as some modes passed to 'OpenMode()', can be Read/Write. In a Read/Write mode, you must call one of a few certain functions between a read call and a write call. These functions will list this effect in their description. Writing to files does not write directly to disk, but to a buffer. It is guaranteed that the contents of this buffer will be written to disk upon a successful call to 'Flush()', or upon the closing of the file. Upon exiting the quest, all open files are closed. There is a limit of 256 file pointers. A pointer does not need to have a file open to count against this limit. Any pointer that returns true from 'isAllocated()' counts against this limit. Calling 'Free()' will deallocate a pointer, thus no longer counting against this limit. If you open many files without calling 'Free()', you may run out of pointers, and be unable to open further files (until you call 'Free()' on some existing pointers). Files are NOT automatically freed if they fall out of scope. You should be sure to manually call 'Free()' before this happens, or you may lose the pointer, and be unable to free it later. Using Own(), you can set a file pointer to automatically free when the calling script exits. Remember: POSIX filesystems are Case-SenSitive.

bool Open(char32[] filepath); bool Create(char32[] filepath);

If the file pointer is not allocated, these will allocate it. Also closes any file that is already open on the pointer. Attempts to open "[zc root]/files/[questname]/[filepath]", in mode 'rb+' for 'Open()' or 'wb+' for 'Create()'. Open will fail if the file does not exist; Create will create it if it does not exist, and wipe the file clean if it does exist.

bool OpenMode(char32[] filepath, char32[] mode_string);

If the file pointer is not allocated, this will allocate it. Also closes any file that is already open on the pointer. Same as 'Open()', but the file is opened with the specified mode. Valid modes (details taken from http://www.cplusplus.com/reference/cstdio/fopen/): "r" | read: Open file for input operations. The file must exist. "w" | write: Create an empty file for output operations. If a file with the same name already exists, its contents are discarded and the file is treated as a new empty file. "a" | append: Open file for output at the end of a file. Output operations always write data at the end of the file, expanding it. Repositioning operations ('Seek()', 'Rewind()') are ignored. The file is created if it does not exist. "r+" | read/update: Open a file for update (both for input and output). The file must exist. "w+" | write/update: Create an empty file and open it for update (both for input and output). If a file with the same name already exists its contents are discarded and the file is treated as a new empty file. "a+" | append/update: Open a file for update (both for input and output) with all output operations writing data at the end of the file. Repositioning operations (fseek, fsetpos, rewind) affects the next input operations, but output operations move the position back to the end of file. The file is created if it does not exist. The letter "b" can be added to the end of any of these (or before the "+", for update modes) to specify a binary file mode. Not doing this will specify a text file mode. Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

bool Remove();

Deletes the file. This will close it, as with Close(), and then delete it from the filesystem. Returns true if successful. The file will be closed, even if the removal fails.

bool Flush();

Flushes the buffer of the file being written to. Writes to a file do not actually write to the file immediately; they instead go to a buffer. Calling this function will force the buffer to be written to disk.

void Close();

Closes any open file connected to the file pointer (which also includes 'Flush()'). Does *NOT* deallocate the pointer, it is still reserved to open new files on.

void Free();

Closes any file as 'Close()', then deallocates the file pointer so it may be re-used.

void Own();

Grants 'Ownership' of the file pointer to the script that calls this function. When the script with 'Ownership' terminates (at the same time its' local arrays are deallocated), this file pointer will automatically be 'Free()'d.

bool isAllocated();

Returns true if this pointer is allocated. This does not necessarily mean a file is open, just that the pointer has a reserved ID.

bool isValid();

Returns true if a file is open on the pointer.

bool Allocate();

Attempts to allocate the file pointer. If it was already allocated, this will re-allocate it without freeing it! Returns true if successful, false if the max number of files is already allocated.

int ReadString(char32[] buf);

Reads a section of characters from the file. Will read either until 'buf' is full, an error occurs, End of File is reached, or a newline character is reached. If it ends due to reaching a newline character, the newline character will be included at the end of the string. Returns the length of the string read into 'buf'.

int ReadChars(char32[] buf, int count = -1, int pos = 0);

Reads a section of characters from the file. Starts placing characters at 'buf[pos]'. If 'pos' is negative, starts at 'buf[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, reads until it fills 'buf', an error occurs, or End of File is reached. If 'count' is positive, reads 'count' characters into 'buf'. Will always add a null character at the end of the read characters. Returns the number of characters read, excluding the added null character.

int ReadBytes(untyped[] buf, int count = -1, int pos = 0);

Reads a section of binary data from the file. Starts placing data at 'buf[pos]'. If 'pos' is negative, starts at 'buf[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, reads until it fills 'buf', an error occurs, or End of File is reached. If 'count' is positive, reads 'count' characters into 'buf'. The binary data read will be 8b; such that reading '1' will place '1' into buf. This means that the binary data cannot contain decimal places. Returns the number of bytes read.

int ReadInts(untyped[] buf, int count = -1, int pos = 0);

Reads a section of binary data from the file. Starts placing data at 'buf[pos]'. If 'pos' is negative, starts at 'buf[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, reads until it fills 'buf', an error occurs, or End of File is reached. If 'count' is positive, reads 'count' characters into 'buf'. The binary data read will be 32b; such that reading '1' will place '0.0001' into buf. This means that the binary data can contain decimal places. Returns the number of ints read.

char32 GetChar();

Reads and returns the next character in the file. Returns -1 if it fails; check 'EOF' and 'Error' to see why.

char32 UngetChar(char32 c);

Un-reads 'c' to the input stream. Returns -1 if it fails; otherwise returns 'c'. This is a READ operation, not a WRITE operation. The file will not actually be modified; but further read operations will find this as the next character to be read. Useful if you read a character, then realize you don't want it.

int WriteString(char32[] str);

Writes the string stored in 'str' to the file. Returns the number of characters successfully written.

int WriteChars(char32[] buf, int count = -1, int pos = 0);

Writes characters from 'buf' to file. Starts at 'buf[pos]'. If 'pos' is negative, starts at 'buf[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, writes from 'buf' until it finds a null character, or reaches the end of 'buf'. If 'count' is positive, writes 'count' characters from buf. Returns the number of characters successfully written.

int WriteBytes(untyped[] arr, int count = -1, int pos = 0);

Writes 8b binary data from 'arr' to file. The binary data written will be 8b; such that writing '1' will write '1' to file. This means that the binary data cannot contain decimal places. Starts at 'arr[pos]'. If 'pos' is negative, starts at 'arr[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, writes from 'arr' until it reaches the end of 'arr'. If 'count' is positive, writes 'count' ints from arr. Returns the number of bytes successfully written.

int WriteInts(untyped[] arr, int count = -1, int pos = 0);

Writes 32b binary data from 'arr' to file. The binary data written will be 32b; such that writing '1' will write '10000' to file. This means that the binary data can contain decimal places; writing '0.0001' will write '1' to file. Starts at 'arr[pos]'. If 'pos' is negative, starts at 'arr[0]'. If 'count' is 0, does nothing and returns 0. If 'count' is negative, writes from 'arr' until it reaches the end of 'arr'. If 'count' is positive, writes 'count' ints from arr. Returns the number of 32b integers successfully written.

char32 PutChar(char32 c);

Writes 'c' to file. Returns -1 if it fails; otherwise returns 'c'.

long Pos;

Read-only. This represents the current position in the file. In binary modes ('Open()', 'Create()', or 'OpenMode()' including "b"), this is the number of bytes into the file, as a long; i.e. '10L' == 10 bytes. In text modes ('OpenMode()' not including "b"), the numerical value may not be meaningful but can still be used to restore the position to the same position later using 'Seek()' (if there are characters put back using 'UngetChar()' still pending of being read, the behavior is undefined).

bool Seek(long pos, bool from_current = false);

Moves the current position of the file. 'pos' is a 32b value, where '1L' represents 1 byte; similar to 'Pos'. If 'from_current' is true, it moves forward from the current position. Otherwise, it moves so that 'Pos' is equal to 'pos'. Using 'from_current'==true in a file open in text mode ('OpenMode()' not including "b") is undefined. Returns true if successful, false otherwise. If successful, this function has the following side-effects:

• All previous calls to 'UngetChar()' are dropped.
• The 'EOF' indicator is set to false.
• Allows switching between reading and writing on a read/write file.

void Rewind();

Rewinds to the beginning of the file. This function has the following side-effects:

• All previous calls to 'UngetChar()' are dropped.
• The 'EOF' indicator is set to false.
• The 'Error' indicator is set to 0.
• Allows switching between reading and writing on a read/write file.

bool EOF;

Read-Only. Returns true if a read call attempted to read past the end of the file. If true, no further read calls will succeed until the position has been changed; i.e. 'Seek()' or 'Rewind()'.

int Error;

Read-Only. Returns 0 if the file has not enountered an error. If an error was encountered, returns an error code number.

void ClearError();

Clears the active EOF and Error indicators. i.e. this writes 'EOF = false;' and 'Error = 0;'.

void GetError(char32[] buf);

Stores a string describing the current error into the buffer provided. Stores an empty string if 'Error == 0'.

Directory Pointers

directory directory pointers allow interacting with directories on the user's system. Each quest has a directory created at "[zc root]/files/[quest name]/", and ONLY directories within this directory are accessible. All paths are relative to this directory. See: LoadDirectory

int Size;

Read-only. The number of files/folders contained in the directory.

bool GetFilename(int index, char32[] buf);

Loads the name of the 'index' file (0 <= index < Size) The name will be placed in the buffer Returns true if successful, false if it fails.

void Reload();

Refreshes the directory, updating the 'Size' and results of 'GetFilename()' to reflect any changes.

void Free();

This will deallocate the directory pointer, so that the pointer ID may be re-used. There is a limit to how many directory pointers may be allocated at once, so be sure to free them when you are no longer using them.

void Own();

Grants 'Ownership' of the directory pointer to the script that calls this function. When the script with 'Ownership' terminates (at the same time its' local arrays are deallocated), this directory pointer will automatically be 'Free()'d.

The Hero-> pointer holds various data and functions related to the player character. Player-> is an alternate token, which accesses the same functions.

int X; int Y; int Z;

Read/Write; These values store the player's position on each of the three axes. If the quest rule 'Sprite Coordinates are Float'at "ZScript->Quest Script Settings->Object" is checked, these values can include up to 4 decimal places; otherwise values are truncated to int.

int Jump;

The speed, in pixels per frame, that the Hero is moving upwards along the Z axis. Unless on the ground, the quest's Gravity is subtracted from this each frame (until it is lower than the terminal velocity value).

int Dir;

The direction the Hero is facing. The Hero may not face diagonally.

int HitDir;

The direction the Hero is currently being knocked back, if they are being knocked back.

int Action;

Represents the Hero's current action state. Writing to this may cause various effects to occur, depending on what the value was previously, and what the new value is. Use the LA_ constants to access this.

int FakeZ;

The Hero's current FakeZ axis position. This value is treated as a second, separate Z axis; Sprites will be offset upwards by this amount when drawn just like the Z axis and shadows will draw if applicable; however, the sprite's hitbox will not be moved upwards into the Z Axis; instead it will be moved upwards on the Y axis, mimicking how Vires and Pols Voice worked in the original Zelda. This value is affected by 'FakeJump' instead of 'Jump'.

int FakeJump;

The current velocity on the FakeZ axis. This value is added to FakeZ every frame; and this value is decreased by the gravity value until it is lower than the terminal velocity value.

bool Climbing;

If true, the Hero is currently holding onto a Sideview Ladder.

bool JumpCount;

The number of jumps the player has jumped in mid-air since the last time they landed. If positive, resets to 0 when landing. Roc's Feathers allow you to jump in mid-air if this is less than the Extra Jumps count of the feather item.

bool Standing;

Read-only. Returns true if the Hero is standing on the ground.

int CoyoteTime;

The number of frames the Hero has been off the ground, max 65535. If the Hero jumps, immediately sets this value to 65535. If this value is not 65535 and is less than a Feather item's Coyote Time value, that feather can be used to jump, even in mid-air.

int HammerState;

Read-only. Returns a value representing the current hammer swing.

0. Not swinging hammer
1. Hammer above head
2. Hammer at angle
3. Hammer hit the ground

int ItemA; int ItemB; int ItemX; int ItemY;

When reading these values, returns the item ID currently equipped to the given button. Returns '-1' if no item is equipped. When writing a value other than '-1', forcibly equips the given item to the given button (force-equip may or may not play nicely with engine active subscreens?). Writing '-1' will un-force-equip an item.

void SelectAWeapon(int dir); void SelectBWeapon(int dir); void SelectXWeapon(int dir); void SelectYWeapon(int dir);

Changes the item equipped to the given button, as though the engine subscreen selection was moved in the specified direction. DIR_RIGHT and DIR_LEFT for this work the same way as the engine's item quickswap right/left.

int SwordJinx; int ItemJinx; int ShieldJinx;

Represents the duration of the Jinx status effects. The sword jinx prevents the Hero from using their sword, while the Item jinx prevents using all other items. The Shield jinx prevents both active and passive blocking via shields. If the value is '-1', the jinx is currently active, with no timer. If the value is '> 0', the jinx is currently active, with that many frames remaining until it wears off on its' own.

int Stun;

Represents the remaining duration of the Stun effect on the player. While stunned, the player cannot do almost anything.

int BunnyClk;

Represents the duration of the Bunny effect. If the value is '>0', the player is a Bunny for that many frames. If the value is '-1', the bunny effect is based on the current dmap being a bunny dmap, and the player not having a Pearl item. Values '-2' to '-99' are reserved for future engine use. If the value is '<= -100', the player will remain a bunny until a script changes this.

bool ClockActive;

If true, a 'Clock' item is active, rendering the player invincible and freezing all enemies.

int ClockTimer;

The remaining time on the 'Clock' effect. If this is 0, but 'ClockActive' is true, then the effect lasts until screen change.

int Drunk;

The value represents the duration of the Drunk status affect, and also affects the intensity of the effect. While active, messes with the players controls, randomly toggling their input (either pressing buttons they did not press, or un-pressing buttons they did press). The longer duration remaining, the higher the rate of input interference.

int Eaten;

The duration the player has been eaten (i.e. LikeLike) for, 0 if not eaten.

bool Grabbed;

True if the player has been grabbed (i.e. Wallmaster)

int HP; int MP; int MaxHP; int MaxMP;

Represents the Hero's health, magic, and the maxes for each of these.

int TileMod;

Read-only. Returns the current total 'Player Tile Modifier'. This is calculated by summing the PTM of all owned items'Active Use' shields only apply their PTM if they are in-use, instead applying a separate 'inactive PTM' if they are not in use. If the Hero is currently a Bunny, PTMs for items that are not 'Usable As Bunny' will not be applied, though the global 'Bunny PTM' will be..

int Tile;

The tile the engine animation has selected to display this frame for the player.

int Flip;

The flip value the engine animation has selected to display this frame for the player.

int CSet;

int ScriptFlip;

If not '-1', this tile will override the engine's selected flip for the player.

int ScriptCSet;

If not '-1', this CSet will override the engine's selected cset for the player.

int Scale;

A scale that will be applied to the player's drawn size (does not affect hitbox)

int Rotation;

A rotation angle (in Degrees) that will be applied to the player's draw (does not affect hitbox)

int ShadowXOffset; int ShadowYOffset;

Offsets to the draw position of the Hero's shadow.

int FlashingCSet;

This returns Link's current displayed cset when taking damage or invincible. If not in one of these states, will return his normal cset. If called before Waitdraw() / player update, results may be off by a frame. If the quest rule 'Invincible Player Flickers' is checked, this is unused.

bool isFlickerFrame();

This returns true if Link is currently in a flicker frame (either invisible or color masked). If called before Waitdraw() / player update, results may be off by a frame. If the quest rule 'Invincible Player Flickers' is unchecked, this is unused.

int FlickerColor;

This sets what color Link is drawn when flickering. If -1, will use the default from Init Data. If the quest rule 'Invincible Player Flickers' is unchecked, this is unused.

int FlickerTransparencyPasses;

This sets how many times the transparency effect is applied to Link's flicker effect. If -1, will use the default from Init Data. If 0, will use a solid color. If the quest rule 'Invincible Player Flickers' is unchecked, this is unused.

void Warp(int dmap, int screen);

Warps the player to the specified dmap/screen. Uses an 'Insta-Warp' type, and uses the 'A' return square.

void PitWarp(int dmap, int screen);

Same as 'Warp()', but instead of positioning the Hero at the 'A' return square, instead the Hero stays in the exact same position.

bool IsWarping;

Read-only, true if a warp is currently in progress.

void WarpEx(int[] ptr);

WarpEX takes an array pointer containing parameters, instead of a set of parameters. Valid parameter sets:

int Steps[8];

If the quest rule 'New Hero Movement'at "Quest->Options->Player" is NOT enabled, this array is used to move the player. When moving horizontally/vertically, the x/y modulo 8 determines which index is used, and that many pixels will be moved. Modifying this array requires care to actually accomplish anything, and it is highly recommended to enable the 'New Hero Movement' quest rule and use 'Hero->Step' above instead.

bool MoveXY(float dx, float dy, bool is_knockback = falseCurrently does nothing for the player. Might in the future. In theory, should be 'true' if the movement is meant to simulate some form of knockback., bool ignore_sideview = falseIf true, allows 'dy' movement regardless of sideview restrictions., bool corner_shove = trueIf true, and either dx==0 or dy==0, then if the movement moves the player into the corner of a solid, they will be shoved around the corner- the same way engine movement handles corners.); bool CanMoveXY(float dx, float dy, bool is_knockback = falseCurrently does nothing for the player. Might in the future. In theory, should be 'true' if the movement is meant to simulate some form of knockback., bool ignore_sideview = falseIf true, allows 'dy' movement regardless of sideview restrictions., bool corner_shove = trueIf true, and either dx==0 or dy==0, then if the movement moves the player into the corner of a solid, they will be shoved around the corner- the same way engine movement handles corners.);

Attempts to move the player by 'dx' in the x direction and 'dy' in the y direction, failing if they are blocked by something they cannot walk through. Returns true if the player moves the full distance, false if the player was blocked at all. The 'CanMoveXY' variant will not actually move the player at all, but will run the collision checks and return true if they CAN move the full distance, or false if they WOULD be blocked.

bool MoveAtAngle(float degrees, float distance, bool is_knockback = false, bool ignore_sideview = false, bool corner_shove = true); bool CanMoveAtAngle(float degrees, float distance, bool is_knockback = false, bool ignore_sideview = false, bool corner_shove = true);

Same as 'MoveXY', but moves by 'distance' in the 'degrees' angular direction.

bool MoveAtAngle(int dir, float distance, bool is_knockback = false, bool ignore_sideview = false, bool corner_shove = true); bool CanMoveAtAngle(float degrees, float distance, bool is_knockback = false, bool ignore_sideview = false, bool corner_shove = true);

Same as 'MoveXY', but moves by 'distance' in the 'dir' direction.

int HeldItem;

The item displayed above the Hero's head (requires them to be in an item holding Action).

int HealthBeep;

Normally between 70 and -1, representing the timer for a non-constant low health beep. Writing '-2' to this prevents the engine from stopping the SFX that is set as the health beep. Writing '-4' to this prevents the engine from both stopping and starting the SFX.

bool Invisible;

If set true, will prevent the player from being drawn.

bool NoStepForward;

If set true, prevents the 'step forward' that occurs when entering a dungeon room.

bool Animation;

If set false, disables the player's engine animation.

int SwitchTimer; int SwitchMaxTimer;

Timer values for the current switchhook effect. If 'SwitchTimer' is '>0', then a switchhook effect is currently active. When 'SwitchTimer' == 'SwitchMaxTimer / 2', the player will swap with the target object. Read-only.

bool SwitchCombo(int pos, int effect);

Switch the player with the given combo position. A hookable combo must be present at that position (on any valid layer) for this to succeed. Use the SW_EFF_ constants for 'effect' to select a visual style for the switch. Returns true if it succeeds, and false otherwise.

int Immortal;

If not 0, the player will not die, even when they have 0 hp. Effects such as bottled fairies will not trigger. If '>0', automatically decrements by 1 each frame. If this value becomes 0 while the player is at 0 hp, the death effect will trigger, including any bottled fairies.

void Kill(bool bypass_revive);

Immediately kills the player, setting their HP to 0, and ignoring 'Immortal'. If 'bypass_revive' is true, revival effects such as bottled fairies will not trigger, and the 'one frame before death' that scripts would use to revive will also be skipped.

lweapon ReleaseLiftWeapon();

Returns a pointer to the held weapon, and causes the player to let go of it.

void LiftWeapon(lweapon weap, int timer, int height);

Causes the player to lift the specified weapon in the same way they lift combos with the Lift Glove. If an lweapon script lifts itself, this also functions as a Waitframe().

lweapon LiftedWeapon;

The weapon currently held by the player. Overwriting this directly will delete any weapon previously held. If an lweapon script lifts itself, this also functions as a Waitframe().

int LiftTimer; int LiftMaxTimer;

The time the current lift operation takes. The LiftMaxTimer is the total time, the LiftTimer starts at the same value but ticks down each frame the lift continues.

int LiftHeight;

1. LIFTFL_DISABLE_ITEMS - If true, the player can't use any items unrelated to lifting. (Items related to lifting, such as bombs with the liftable flag set or a Lift Glove, will throw the held item regardless)

RandGen Pointers

randgen randgen pointers reference specific random number generators. You can create and seed them yourself. Any randgen pointer with a value of NULL can be used to reference the engine's RNG. The global pointer RandGen-> is available as a null randgen pointer. See: LoadRNG

void Own();

Grants 'Ownership' of the randgen pointer to the script that calls this function. When the script with 'Ownership' terminates (at the same time its' local arrays are deallocated), this randgen pointer will automatically be 'Free()'d.

Stack Pointers

stack stack pointers allow storing and managing large sets of data, similar to arrays. The max storage of a stack is 2,147,483,647 elements, compared to arrays which have a maximum of 214,748 elements. Stacks also have various functions for accessing the data. See: LoadStack

untyped PeekFront();

Returns the first element in the stack, without removing it.

void Clear();

Removes every element from the stack.

untyped Get(long ind);

void Set(long ind, untyped val);

Overwrites the element at the index 'ind' (which is a LONG value) with 'val'. This means that '0L' is the first element, '1L' is the second, etc. If an invalid index is given, nothing happens.

void Free();

De-allocates this stack pointer, so that its' pointer ID may be re-used. You may only have a limited number of stack pointers active at a time; freeing them when you are done with them helps not reach the limit.

void Own();

Grants 'Ownership' of the stack pointer to the script that calls this function. When the script with 'Ownership' terminates (at the same time its' local arrays are deallocated), this stack pointer will automatically be 'Free()'d.

Returns the width/height, in pixels, of the message text - not including line wrap / breaks. This is the width/height that would be used to call DrawString with this message string and font. TextHeight() is effectively the same as calling Text->FontHeight() using the message's font. TextWidth() is effectively the same as using messagedata->Get() to get the text into a ZScript string, and then passing that with the message's font to Text->StringWidth().

int GetRenderTarget(); void SetRenderTarget(int rt);

Gets/sets the current "Render Target". Most times this should be 'RT_SCREEN', though versions older than 2.55 required using this for bitmap drawing. 2.55's bitmap pointers effectively obsolete the render target system, and should be used instead of this. Uses the constants RT_SCREEN for the screen, and RT_BITMAP0 through RT_BITMAP6 for the 6 old-style bitmap targets.

void Own();

Grants 'Ownership' of the bitmap pointer to the script that calls this function. When the script with 'Ownership' terminates (at the same time its' local arrays are deallocated), this bitmap pointer will automatically be 'Free()'d.

void Read(int layer, char32 filename[]);

Reads from the specified image file into the bitmap. Read() will fail if:

• The file is corrupt:
• PNG, JPEG, or other 'compressed' formats may abort if the file is corrupt.
• Formats such as .BMP or .TGA may read up until missing data, as they are linear.
• The file is missing.
• The filename is incorrect. Remember that POSIX filesystems are Case-SenSitive.

Writes from the bitmap to the specified image file. Requires one of: .png,.gif,pcx,.tgx,.bmp. Fails otherwise. Will not replace an existing file, unless allow_overwrite is true. Will automatically create missing directories on the specified path. If "All bitmap-> and FileSystem-> paths relative to quest 'Files' folder"at "ZScript->Quest Script Settings->Instructions" is enabled, paths are relative to the quest's specific directory; otherwise they are relative to the ZC folder.

void WriteTile(int layer, int x, int y, int tile, bool is8bit = true, bool mask = false);

Writes a 16x16 area from the bitmap to the tile tile. The tile's 8-bit status will be set to the value of is8bit. If mask is true, the draw will be an Overlay- otherwise it will overwrite.

void Create(int layer = 0, int width = 256, int height = 256);

Creates a bitmap on the pointer of width by height, destroying any data that was previously on the pointer. If "Old Args for CreateBitmap and bitmap->Create()"at "ZScript->Quest Script Settings->Instructions" is enabled, then width and height are swapped with each other.

void Clear(int layer = 0);

int CountColor(bitmap mask, int x, int y, int checkColor, int maskColor = -1);

Checks the area of this bitmap specified by the area on the mask bitmap which matches the maskColor. For a maskColor of -1, all non-zero values will match. Returns the number of pixels in said area that match the checkColor on this bitmap. For a checkColor of -1, all non-zero values will match. The area checked is from x,y to x+mask->Width,y+mask->Height. If this goes out of bounds, the out of bounds area is ignored. This does not account for this frame's draws that have yet to happen.

void Dither(int layer, bitmap mask, int color, int ditherType, int ditherArg);

Draws color to this bitmap, in the area specified by the mask. Any pixel on the mask which matches the maskColor will be drawn. If no maskColor is specified, all non-zero pixels will be considered matching. If a startMaskColor+endMaskColor are defined, colors between them, inclusive, will be considered matching.

void MaskedBlit(int layer, bitmap mask, bitmap pattern, bool repeatPattern); void MaskedBlit(int layer, bitmap mask, bitmap pattern, bool repeatPattern, int maskColor); void MaskedBlit(int layer, bitmap mask, bitmap pattern, bool repeatPattern, int startMaskColor, int endMaskColor);

Same as MaskedDraw, except instead of drawing a specified color to this bitmap, it draws from a pattern bitmap. If repeatPattern is false, the area from 0,0 to pattern->Width-1,pattern->Height-1 will be drawn. If repeatPattern is true, the entire bitmap will be drawn, repeating the pattern both horizontally and vertically tiled.

void ReplaceColors(int layer, int color, int startCol, int endCol);

Draws an area specified by the (sx,sy,sw,sh) from this bitmap to the destination area (dx,dy,dw,dh) of the target bitmap. If 'rotation' is non-zero, rotates the draw around the (cx,cy) point. 'lit', if non-zero, will attempt to tint the draw based on that palette index. If 'mask' is false, color 0 will draw as color 0 instead of transparent.

void BlitTo(int layer, bitmap source, int sx, int sy, int sw, int sh, int dx, int dy, int dw, int dh, float rotation = 0Degrees, int cx = 0, int cy = 0, int mode = 0BITDX_ constants, int lit = 0, bool mask = true);

Draws a number, in the font specified using FONT_ constants, with the top-left at (x,y). The number will be exactly width by height pixels, in the color. If background_color is not -1, it will be drawn behind the number in a rectangle. Up to 'num_decimal_places' places after the decimal point will be shown.

void DrawCharacter(int layer, int x, int y, int font, int color, int background_color, int width, int height, char32 char, int opacity = OP_OPAQUE);

Draws a single character, in the font specified using FONT_ constants, with the top-left at (x,y). The character will be exactly width by height pixels, in the color. If background_color is not -1, it will be drawn behind the character in a rectangle.

void DrawString(int layer, int x, int y, int font, int color, int format, int background_color, char32 str[], int opacity = OP_OPAQUE);

Draws a string, in the font specified using FONT_ constants, in the 'color'. If background_color is not -1, it will be drawn behind the string in a rectangle. Where the string is drawn depends on the format:

• TF_NORMAL: Top-left of string is at (x,y)
• TF_CENTERED: Top-center of string is at (x,y)
• TF_RIGHT: Top-right of string is at (x,y)

void DrawString(int layer, int x, int y, int font, int color, int format, int background_color, char32 str[], int opacity, int shadow_type, int shadow_color);

Same as the above version of DrawString(), except the string is drawn with a shadow. The shadow's style is defined as SHD_ constants, and the shadow will be drawn in the specified shadow_color.

void FastTile(int layer, int x, int y, int tile, int cset, int opacity = OP_OPAQUE);

Draws the specified tile in the specified cset, with the upper-left at (x,y).

void DrawTile(int layer, int x, int y, int tile, int blockw, int blockh, int cset, int xscale = -1, int yscale = -1, int rx = 0, int ry = 0, int rangle = 0Degrees, int flip = 0, bool transparency = true, int opacity = OP_OPAQUE);

Draws a block of tiles starting from the specified tile, in the specified cset, with the upper-left at (x,y). The size of the tile block is determined by blockw and blockh, which must be integers from 1 to 20 inclusive. If xscale and yscale are both >0, the draw will be stretched to be xscale by yscale pixels. Otherwise, the draw will be 16*blockw by 16*blockh pixels. If transparency is false, color 0 in the tile will be drawn as color 0 instead of transparent. The draw will be flipped based on flip, using the FLIP_ constants. If 'rangle' is not 0, it will rotate the draw around the (rx,ry) point. If 'rx' OR 'ry' is <= -777, it will rotate around the center of the draw instead of an arbitrary point.

void DrawTileCloaked(int layer, int x, int y, int tile, int blockw, int blockh, int flip = 0);

Similar to DrawTile(), but draws with a "cloaked" effect. This means that it does not actually draw the tiles, but instead it distorts the destination bitmap in the draw area based on the pixels in the tiles.

void FastCombo(int layer, int x, int y, int combo, int cset, int opacity = OP_OPAQUE);

As FastTile(), for the current tile of combo.

void DrawCombo(int layer, int x, int y, int combo, int blockw, int blockh, int cset, int xscale = -1, int yscale = -1, int rx = 0, int ry = 0, int rangle = 0Degrees, int flip = 0, bool transparency = true, int opacity = OP_OPAQUE);

As DrawTile(), but for the current tile of the combos.

The texture is mapped from a tile or tile block if texture > 0, or a combo/combo block if texture <= 0. (Ex: texture = -32 will use combo 32 as a texture). w, h must be values from 1 to 16, and must be powers of 2. For bitmap->Quad(), if render_source is a valid bitmap, a section of it (based on w, h) will be used as the texture instead.

void Triangle(int layer, int x1, int y1, int x2, int y2, int x3, int y3, int w, int h, int cset, int flip, int texture, int render_modePT_ constants, bitmap render_source = NULL);

NOTE: the bitmap render_source parameter is only available for bitmap->Triangle(), not Screen->Triangle(). Draws a triangle with the 3 specified corners, drawn counterclockwise from (x1,y1). The texture is mapped from a tile or tile block if texture > 0, or a combo/combo block if texture <= 0. (Ex: texture = -32 will use combo 32 as a texture). w, h must be values from 1 to 16, and must be powers of 2. For bitmap->Triangle(), if render_source is a valid bitmap, a section of it (based on w, h) will be used as the texture instead.

void Quad3D(int layer, int pos[12], uv[8], csets[4], size[2], int flip, int texture, int render_modePT_ constants, bitmap render_source = NULL);

NOTE: the bitmap render_source parameter is only available for bitmap->Quad3D(), not Screen->Quad3D(). Draws a 3d quad with the 4 corners specified in pos as {x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4}. uv specifies texture coordinates as {x1,y1,x2,y2,x3,y3,x4,y4}. size specifies the texture's {w,h}. The texture is mapped from a tile or tile block if texture > 0, or a combo/combo block if texture <= 0. (Ex: texture = -32 will use combo 32 as a texture). For bitmap->Quad3D(), if render_source is a valid bitmap, a section of it (based on {w, h} in size) will be used as the texture instead.

void Triangle3D(int layer, int pos[9], uv[6], csets[3], size[2], int flip, int texture, int render_modePT_ constants, bitmap render_source = NULL);

NOTE: the bitmap render_source parameter is only available for bitmap->Triangle3D(), not Screen->Triangle3D(). Draws a 3d quad with the 4 corners specified in pos as {x1,y1,z1,x2,y2,z2,x3,y3,z3}. uv specifies texture coordinates as {x1,y1,x2,y2,x3,y3}. size specifies the texture's {w,h}. The texture is mapped from a tile or tile block if texture > 0, or a combo/combo block if texture <= 0. (Ex: texture = -32 will use combo 32 as a texture). For bitmap->Triangle3D(), if render_source is a valid bitmap, a section of it (based on {w, h} in size) will be used as the texture instead.

void DrawLayer(int layer, int source_map, int source_screen, int source_layer, int x, int y, float rotation = 0, int opacity = OP_OPAQUE);

Draws the entire layer source_layer from the screen source_map, source_screen. If rotation isn't 0, the layer will be rotated around its' centerpoint.

void DrawScreen(int layer, int source_map, int source_screen, int source_layer, int x, int y, float rotation = 0);

Draws the entire screen source_map, source_screen. If rotation isn't 0, the screen will be rotated around its' centerpoint.

void DrawFrame(int layer, int x, int y, int tile, int cset, int width, int height, bool overlay = true, int opacity = OP_OPAQUE);

Draws a frame using a 2x2 block of tiles, the upper-left tile specified as tile. This works the same way as the default "blue frame" on engine subscreens. width, height indicate how many 8x8 pixel squares the frame is wide/high- so 4,4 would give a 32x32 pixel frame. If overlay is false, color 0 in the frame tiles will be drawn as color 0 instead of transparent.

void Polygon(int layer, int num_points, int vertices[], int colour, int opacity = OP_OPAQUE);

Draws a polygon, where vertices is an array, of which the first num_points*2 indexes are made up of num_points x,y pairs. (ex for num_points = 4, vertices = {x1,y1,x2,y2,x3,y3,x4,y4}).
