Argument Description disable If set to true the depth buffer will be disabled for surfaces.
This function disables the automatic depth buffer generation for all surfaces in the game. Normally all surfaces have depth buffers so if you draw 3D objects to them then it'll sort them properly by depth, however allocating depth buffers essentially doubles the size of surfaces, which could be an excessive and unnecessary overhead especially if your game is very memory intensive.NOTE: This function is currently only valid for the Sony Playstation 4 target platform.
if surface_get_depth_disable() == false
The above code will check the current state of the surface depth buffer and if it is enabled, it will disable it instead.
