Problem with physics objects in groups and group coordinates

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

You can neither scale groups nor move them and have physics work consistently.

All groups must have the same scale and coordinates.

Additionally, scaling the display object has no affect on the body.

Set hybrid draw mode to see what I mean.
