problem with collision?

[shahramy]

hi
when I use object.applyforce to shoot a ball, the physics engine can not notify collision if force is high. the power of force has to be high which throws the ball more distance. I know the ball hits the objects but physic engine do not notify!!!!

If the collision shape is thin it may not detect the collison, especially when the ball is moving at higher speeds. Try making the collision shape thicker to correct for this.
