Here is the code from the example “Physics\DebugDraw”, and i changed and added few lines of it. If u run it and let the ball falls on the ground, u will find u can move the ball. But if u change the ball’s physic shape to Box, then u can move it. I think it’s bug. and hope to find answers here.
Any help would be nice. Thanks.
