So, in my game I have little objects that get kicked around a lot. When the enemy kicks it, it flys sometimes off the map. I want it to act like its heavier, so it doesn't fly around. Is there a way to do that, like someone change its mass?
If you enable the CustomPhysicalProperties you can override certain settings like density. However these only go so far until it caps out.
Another way however which might be simpler is to wall off the area you're trying to keep the objects inside. Just make invisible walls all around and the parts cannot get out.
