I didn't want to report a bug until I was sure I'm doing something wrong. My layout is really simple, this is all of it:
1 arena made from individual bouncy walls.
1 player object, not too big, about 64x64.
3 small square objects, instances, that are just things the player will eat. 20x20
They all have physics. Gravity is turned off. They bounce around the arena and the player object. But I noticed something weird. Sometimes when the player hits one of the little squares it affects all of them.
Like say the player moves into one of the instances, then all the instances react whether they're touching the player or not.
The game will be very physics based so this is pretty bad. Is there something I've set up wrong?
