d3d_vertex_colour(x, y, z, col, alpha)
| Argument | Description |
|---|---|
| x | The x coordinate of the vertex. |
| y | The y coordinate of the vertex. |
| z | The z coordinate of the vertex. |
| col | The colour to draw this vertex with. |
| alpha | The alpha to draw this vertex with (0-1). |
Returns: N/A
This function defines the position of a vertex for a primitive,
with its own colour and alpha setting. The final look of the
primitive will depend on the primitive type chosen to draw and the
order with which you add the vertexes to it (see d3d_primitive_begin for
more information) and the vertexes with different colours and
alphas will blend smoothly from one to the other. To end and draw
the primitive you must call d3d_primitive_end.

The above code will draw a tetrahedron standing on the z=0 plane with its top coloured red and fully opaque at z = 200, while its base will be blue and transparent.
