|surface_id||The ID of the surface to get the width of.|
This function returns a special pointer for the surface
texture. This value can then be used in other draw functions,
particularly in general 3D and some of the 2D primitive
NOTE: When working with surfaces there is the possibility that they can cease to exist at any time due to them being stored in texture memory. You should ALWAYS check that a surface exists using surface_exists before referencing them directly. For further information see Surfaces.
tex = surface_get_texture(surf);
draw_vertex_texture(0, 480, 0, 0);
draw_vertex_texture(640, 480, 1, 0);
draw_vertex_texture(640, 480, 1, 1);
draw_vertex_texture(0, 480, 0, 1);
The above code will draw a 4 vertex triangle strip textured with the texture held in the "tex" variable, which is itself taken from a previously created surface.
