NewtonCollisionCollideContinue Problems

Postby pHySiQuE » Sat Oct 12, 2013 3:30 pm

I am using NewtonCollisionCollideContinue() for sphere casting. This video shows two issues with the function:

  • On the boxes, the picked position can sometimes "fall" below the surface, or the collision misses (see time 0:26).
  • The terrain heightfield never results in any contacts.

Can you comment on this? It appears to be a very deep systemic problem.

Ok, I believe I fixed this now. Please sync to SVN and try again.
This was a bad bug yes.

I do not use Newton's scaling feature. I just generate my own shapes as needed.

Thanks, I will check it out.
