Hello!  We want to shoot a ball towards a specific direction using user touch events. The ball should hit another physics objects. The problem arises when we scale the group of the physics objects which the ball should hit.   if we do not scale the ball the collisions do not work.  If we scale the ball and the group also the collision work but the ball is not shot from the right place(event.yStart and event.xStart have changed).   How can we solve this?  thanks in advance
