This has got me stumped. im making a 2d pool game. How would i get the animations of the rolling balls to accuratly match the direction and speed they are going. Also, do you know any *trick* way of doing this. Thanks in advance.

The easiest way i can think to do it would be to have only a sprite of a white ball, and then use code to simulate the stripes, and use smallersprites to go over the top of your ball sprites for those circled numbers.. like a direct draw type thing?

I dont know. thats just my guess. im really not a reliable source for this

Aha, funny you should mentioned this as I came across the same problem myself a while ago but there is a relatively easy solution. The trick is to use three layers. On the bottom you have your pattern. That is masked by a circular hole so you can only see a circle shape made up of the pattern. On top of that you blend a little bit of a shadow to give a curved effect. Now, when the ball moves, slide the pattern layer in the same direction and it will look like it is rolling.

I've tried to give you an idea of what I mean using a Photoshop document here. If you slide the 'pattern' layer around it looks like the ball is rolling.

Hope that helps.

You could have actual 3D models that you rotate to desired position and render to a 2D texture each frame, then blit the texture, but I guess that's beyond the scope of this forum.

In any case, ghosted's solution is quite clever, simple, and looks very, very good. I recommend using that if you don't want to deal with 3D objects (which might be overkill anyway).
