Hi!

Maybe I'm doing something wrong, but it seems to me, that PhysHitCallback's hit sequence is wrong. I try to simulate bullethit with penetration, but if I stop checking with return false (in hit method), sometimes I get the wrong hit. For example, if I stop it at the first collision, then sometimes the bullet goes through a wall (without hit), and hits only the ground behind the wall. If I don't stop it, then hit the both, and its good. I'm testing it for days now, and the code seems okay to me, I can't find any problem.

Hi,

It may be possible that PhysX does not return the collisions in order, for performance reasons.
This would need to be checked in either PhysX SDK headers or documentation.

Okay, thanks for your fast answer! Then I'll looking for that, and respond if I'll find something about that.

Maybe I should sort my impact container by the hit distances to get the right sequence, and only after compute if the bullet is penetrate, or stop and be killed.
