[ODE] contact points

[Lewis Foster]

Jaroslav,

Yes that's correct and in my case it works fine in the situation where the
normal points in to the box that is in the air. What i found to cause a
problem was when the normal pointed toward the box on the floor it was
effectively adding contact points to the box on the floor which had no
effect as it couldn't move.

The obvious solution is to add contact points to BOTH geoms with an inverted
normal on one, this seems to have fixed my problem although they're still
acting somewhat erratically. Is this how it should be done, contacts on both
geoms?

David, good to hear some enthusiasm for it. I'm still not happy with the
collision behaviour and i dare say the code is quite inefficient but i'll
see where I can get with it. I'm going to test it with different convex
objects and see how it behaves then i'll post the results.

Thanks

Lewis
