Features

• option to disable transparent darkrooms stacking multiple transparent layers d9d3ac8e4

ZScript

• add template types to some internal functions 633d75471  

  The following internal functions have switched from using untyped to template types:

  void ArrayPushBack(T[] arr, T val)
  void ArrayPushFront(T[] arr, T val)
  void ArrayPushAt(T[] arr, T val, int index)
  T ArrayPopBack(T[] arr)
  T ArrayPopFront(T[] arr)
  T ArrayPopAt(T[] arr)
  void ArrayCopy(T[] dest, T[] src)
  int SizeOfArray(T[] arr)
  void ResizeArray(T[] arr, int sz)
  void OwnArray(T[] arr)
  void DestroyArray(T[] arr)
  
  void printfa(str* format, T[] args)
  void sprintfa(str* buf, str* format, T[] args)
  
  T Min(T arg1, T arg2, ...T rest)
  T Max(T arg1, T arg2, ...T rest)
  T Choose(T arg1, ...T rest)

  This means that the type T must match other occurrences of T throughout the entire signature, given the types of the parameters used by the callsite. For example, this code no longer compiles:

  printfa("hello %d", 1) // Second param is not an array
  Object objects[] = {new Object()};
  ArrayPushBack(objects, 1) // Second param is not an Object
  int v = ArrayPopBack(objects) // Cannot convert Object to int

  Note: for now, SizeOfArray and ResizeArray still allow char32 for their array parameters, since that is common for string operations and we don't have a formal string type yet.

• add garbage collector for automatic memory management d4bc547f8  

  Objects created by scripts are now automatically deleted when they are no longer reachable from any script.

  This removes needing to manually delete objects you create (either with the delete operator or Free()), and mostly removes any reason to ever call Own().

  See the new "Object Memory Management" section in ZScript_Additions.txt for further details.

Bug Fixes

Player

• 'Spotlight' combos on changer/ethereal ffcs still shooting light 99d4786b9
• fix buggy color flickering on big player sprites 5a6bf306e
• hardcode 120 for zscript alpha register d23a9bdd1  

  This fixes some quests that only look at the alpha version and, seeing it was now 0 presented an error message to the user.

Editor

• 'View Map' favorite command skipping menu b9ea47f75
• Crash in ZInfo menu if descriptions are long 9546a257e

ZScript

• some array-related functions breaking for arrays >65535 in size f6ad9203a
• class variables not shadowing global vars properly 46ed8bf58
• bad optimization causing global vars to sometimes read incorrectly b000fc9e2
• some wrong error messages related to mapdata FFC access bf68795d9
• websocket pool being destroyed on 'cont_game()' ae375c530
• socket arrays sometimes going invalid? 12e3b9a92  

  Patched the issue here, not the cause. Not sure what caused it to sometimes go invalid, but a validity check seems sane.

• 'delete' within a destructor being buggy 0bb0da1de
• disallow casting custom objects to unrelated types ed6faae63  

  A bug in type conversion allowed this code to compile:

  Object obj = new Object();
  int number = obj;
  int numbers[] = {obj};

  The above code now produces a compiler error.

• derive language runtime version from compiled scripts a772dd873  

  The script engine checks the version a script was compiled in to vary some behavior. Previously this version was set to the section version in the qst file format, but that is updated even if scripts were not re-compiled. Now we look directly at the script metadata to set this version. This avoids issues with saving a quest in a new version without a recompile.

Refactors

ZScript

• standardize script object management be20f347b  

  This keeps script-created objects in the same map, gives all objects a unique id, and implements allocation and retrieval for any object type using the same methods. This reduces some duplicated code, and should help with implementation of a potential garbage collector feature.

  Bitmap objects are a bit special, and still need to be refactored.

• document, clean up, and sanity check websocket stuff ce2f07d9c
• document, clean up, and sanity check websocket stuff 764e539e0
• migrate user_bitmap to script object system 68329daf9  

  Incidently, this increases the maximum number of user bitmaps to 256.

Tests

• add playground_bitmap_credits.zplay d6b398ad4

CI

• use macos-13 for newer clang

    Relevant changes:

  • ci: update to macos-13 in other places too 6bb570d37
