d3d_vertex_texture(x, y, z, xtex, ytex)
| Argument | Description |
|---|---|
| x | The x coordinate of the vertex. |
| y | The y coordinate of the vertex. |
| z | The z coordinate of the vertex. |
| xtex | Starting x coordinate within the texture. |
| ytex | Starting y coordinate within the texture. |
Returns: N/A
This function defines the position of a textured vertex for a
primitive. The final look of the primitive will depend on the
primitive type chosen to draw (See d3d_primitive_begin for
more information), the order with which you add the vertexes to it
and the position of the start point you set for the texture. To end
and draw the primitive you must call d3d_primitive_end.
Note: In a texture the position (0,0) is the top-left
corner, but often when using projections the bottom-left corner is
(0,0). In such a case you might need to flip the texture
vertically.
var tex;
tex = background_get_texture(back);
d3d_primitive_begin_texture(pr_trianglelist, tex);
d3d_vertex_texture(0, 480, 0, 0, 0);
d3d_vertex_texture(640, 480, 0, 1, 0);
d3d_vertex_texture(640, 480, 1000, 1, 1);
d3d_vertex_texture(0, 480, 1000, 0, 1);
d3d_primitive_end();
The above code will draw a 4 vertex triangle list textured with the texture held in the "tex" variable.
