Thanks Fastlane. I will have a try myself first. I want to learn how physics works, and it will be very satisfying to do it myself. If I get stuck or you can improve on my bhest efforts, then I'll take you up on your offer.

I still have some research to do on this (i.e. I'm going to go and play some pachinko), but if the physics really isn't that hard (???), then I could get that part done then come back to the design of the board later.

I don't only want the balls on the playing field moving. One of the most exciting aspects of Pachinko is that when you start winning, you keep winning and balls start spewing out everywhere. (Funny thing is the Japanese one armed bandits do the same thing with coins, but that's another story). Eventually you have buckets of the things. I have to work out a way simulate that. ONce balls come to rest, they won't need a physics action applied to them, and the balls themselves could be represented by 2d sprites.

I put my order in for 3dgs pro this morning.
