shaders_are_supported();
Returns: Boolean
This function will do a check to see if the chosen target
platform supports shaders, returning true if they do, and
false if they do not.
global.GFX = false;
if shaders_are_supported()
{
if shader_is_compiled(sh_glass) &&
shader_is_compiled(sh_warp)
{
global.GFX = true;
}
}
The above code will set a global variable to false, and then if the platform supports shaders and both the shaders being checked have compiled correctly, it will be set to true.
