More Collision/Physics Difficulties...

I need the player to stop when he hits a collision polygon. No bounce, no rotation, I just want the player to stop. I took care of the bounce and rotation with a collision material, but when something hits the player or the players collision polygon hits another at an angle the player drifts off. I can't seem to stop this any help would be appreciated.

EDIT:
I also have the setCollisionActive( true, false) so the player doesn't recieve collisions, yet he still does.
