Hi all,
I'm trying to mix 2d and 3d in the same game but all I get are 2d sprites drawn over 3d objets.
i'd like to know if is possible "insert" 3d objects between two 2d graphics with different depth (using the spritedepth() command).
I know I can emulate the effect using little 3d planes to simulate sprites but I'd like use the benefits of 2d sprites and the 3d objects at same time. Is it possible?
Thanks in advance =)

In the next version there will be a new command Set3DGlobalDepth( int ) which will set the sprite depth that all 3D objects should be drawn at. Sprites with a depth greater than this will be drawn behind and sprites with a depth less than this will be drawn in front.

I have a question perhaps on the same theme of 2d and 3d. Is there anyway to make box2d work with 3d plains? Or will there be a separate physics system for 3d?

Box2D will not interact with 3D objects. There will eventually be a 3D physics system for 3D objects.

Funny you should say that, I just made a demo of just that for the next ADG newsletter

I'll attach a version here so you can have a look. There will be an article to go with it, if you want to register on baxspace.com you'll get the newsletter in about 3 days time.

Clever, as long as everything remains on a 2D ground it can indeed be simulated by Box2D

You could easily enough do a side scroller like that as well
