I'm going to have a play this evening to see how easy we can just throw this stuff in.
Rob,
Do not let this suggestion interupt you current work. I desire to contribute, so, allow me take a deeper look into it. I'm not certain that the entire 2D Sprite command set is totally supported in SpriteMaster.
My goal will be to aquire or develop a 3D Sprite System that functions exactly like the 2D Sprite System, so, all you have to do Include "3DSprite.bb", Set Graphics3D, and toss in Update/Capture/RenderWorld into the update loop. Hopefully achieve integration with very little or no modification to current source.
PS: Maintain 2D Style. Full 3D characters are cool, but, are not necessary. Keeping the vintage 2D style graphics will keep the current work flow.
