|back||The index of the background to use.|
This function returns a pointer for the background texture page.
This value can then be used in other draw functions, particularly
in general 3D
and some of the 2D primitive
functions, as well as the Shader functions. You can get more
information about the returned texture page using the different
texture_ functions found here.
tex = background_get_texture(back);
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.
