Multiple Springs?

Is it possible to apply more than one cpDampedSpring to a body? I just tried and failed (only the last one to be applied seems to have any effect). The docs didn't mention this, so I wasn't sure if it was a bug in my code, a bug in Chipmunk or just not implemented. Do I need to combine them manually somehow?

Thanks.

I'm lying in bed now, so I can't check the code, but I've just realised that I'm probably resetting the forces before each call. Which I'm sure would cause this problem, so I'll fix that tomorrow and hopefully that'll work. I hope no one has wasted any time thinking about this.

Yeah, it should work. I didn't really get a chance to look at it this weekend. (too much sailing and getting sunburned)

The only potential problem is that the damping as applied outside of the solver won't be 100% correct, so it could act funny if you are applying multiple springs with high damping values.

It works very well now: http://www.maximile.net/stuff/springyh3.mov
