I have a game with lots of instances of the same sprite. They all have the physics behaviour. When they collide, I'd really like them to stick together ... but I always end up with a expression that looks like "On collision with Sprite ... Add revolute joint to Sprite", which doesn't work (because I can't work out how to select two different instances of the same object inside a loop).
Below is a non-working example of what I'd like to achieve. The two balls should hit each other an join together in one physics object.
(Apparently, even though I've got a paid licence I can't post links ... so sorry I can't post an example...)
Any ideas on the best way to achieve this?
