buffer_set_surface fix for GameMaker: Studio

Quick links: explanation · source code
Versions: GameMaker: Studio 1.4.1773 .. 1.4.9999
Platforms: Windows, Windows (YYC)

This extension fixes the buffer_set_surface function in GameMaker: Studio by providing a fallback implementation if the original function doesn't work.

How to use

Import the GMEZ file from itch (right-click on the Extensions folder in the resource tree, pick "Import extension") or download the example project (GMZ)

You don't have to replace any function calls - the extension will redirect calls to the original function automatically.

API

• buffer_set_surface_detect() This function detects whether the original buffer_set_surface function works correctly and sets buffer_set_surface_uses_fallback accordingly.

  It will be automatically ran when called buffer_set_surface for the first time, but you can also run it yourself if you need to know whether the fallback function is going to be used without calling buffer_set_surface.

• buffer_set_surface_uses_fallback This global variable indicates whether the fallback function is being used.

  It is true if it is, false if it isn't, and undefined if neither buffer_set_surface nor buffer_set_surface_detect have been called yet.
