I have long work in my game and I would like to change some things using Physic-Engine, and only when I put extension Physic-Engine into the frame (0 objetc with physics movement only for put the extension), that frame frozen when start the frame in iOS device, in the computer works perfect. I made a new game with Physic-Engine extension into the frame and works perfect.
I think maybe I need optimize my game because is too much for use Physic-Engine.
Somebody knows about this?
thanks so much and sorry for my English.
