3d Triangles

I am sure that this has been requested before, but I want to request it too. I would like a form of the 3D box, but well... a triangle, that sprites can walk on. For instance, you can set the 3d box to solid and walk on it, but if you rotate it collisions won't rotate with it. Its not like a super request. It would however be cool if you guys put it in eventually.

You want 3d Triangles?

Here is an example using a sprite with a custom collision mask (a triangle) for collisions and a distort map for the 3d look.

Note: if the sprites are re-sized from their original size the distort maps will get messed up.

EDIT: Fixed the download.
