Sorry for my ignorance, but what "define macros properly" mean here? I thought GMS1 only allowed you to put macros in a special file, not in-line.
Also, is there any way to automatically generate the function calls for extension? It seems you have to manually add them to the GMS1 IDE before being able to actually call Haxe. Any way around this?
Also, after compiling, I've copied the code inside the .gmx_ file and put it inside the extension's .gml file, is that correct?
