Collision zones ghost in groups...

I have come across several instances that when I insert a physics body into a group…the calculated collision detection doesn’t not match the actual collision area nor the asset’s visible location.

When I use the hybrid draw mode, it shows the collision area where it should be. However, balls (or whatever) that are supposed to collide with it do not collide there…but actually collide in alternate locations. I have found that the place they collide are where the visible collision zones would be if they objects are not grouped.

It appears the group insertion doesn’t tell the physics engine that the collision zone has moved.

If you need examples…let me know. [import]uid: 9492 topic_id: 7295 reply_id: 307295[/import]

There’s a good discussion of physics and groups in this thread:

Thanks for the heads-up on this. Looks like I may need to re-think things. [import]uid: 9492 topic_id: 7295 reply_id: 25777[/import]
