sprite_add_gif for GameMaker

Quick links: source code
Supported platforms: All (see notes below)
Supported versions: GameMaker Studio≥2.3

This extension allows you to load animated GIFs as sprites into your GameMaker games!
It is based on Haxe "format" library implementation contributed by Yanrishatum.

Functions

• sprite_add_gif(path, xorigin, yorigin, ?delays_array)➜sprite
  Equivalent of sprite_add. Path should point to a valid GIF file.
  If delays_array is provided (optional), per-frame delays (in centiseconds) will be pushed to it, allowing for accurate playback (see demo project).
• sprite_add_gif_buffer(buffer, xorigin, yorigin, ?delays_array)➜sprite
  Same as above, but takes a buffer with GIF file inside.

Setting up

Import the GifHx script into your GMS≥2.3 project.

Notes

• As a pure-GML extension, it isn't super fast.
  Doing LZW decompression in GML hurts! (though slightly better with YYC)
  Probably don't use this to load multi-megabyte GIFs.
  It may be possible to optimize the code a little.
• As of beta runtime 23.1.1.190, doesn't work on HTML5 due to a code generation bug.
  This will probably get fixed sometime soon.
• Note that the example project is mostly intended for Windows because GM doesn't implement file dialogs on other platforms.
  The default sample GIF will still load though!
