Hi Ingemar, did you see this site?

Maybe you have, but if not, it might help

cheers,

I have seen it but overlooked it, since the collision response part is a bit too brief, and that's the hard part! But I have tried the demo, and it works surprisingly well! So I guess I'd better give that collision response section another try.

And I do work in 2D. That's enough for a simple physics-based game.

Thanks for the pointers! I think I have a working system now. BTW, here is the page that was my inspiration (although it lacks collision handling): http://www.aquinhasa.com/?p=56

I just tried it again and it popped right up. Maybe it was temporarily down?

I don't know if my ragdoll will ever be perfect, now I have some problems with sticks passing through polygons again, but I think it is less common than before. The big step was to add a size to every particle, so the actual point is kept outside the polygon. Then I get less problems with numerical precision, which often occurred when a particle was right at an edge.
