I’d like to know whether there is some order in which collision events get triggered i.e. is there some order like first all OnCollisionEnter get triggered or whether they get triggered all on one object first and then on another object randomly.
We have an execution order document here: Unity - Manual: Order of execution for event functions
It seems that Triggers are dealt with before Collisions in every cycle. Because the physics module is run by Fixed update they can be call more frequently than Update
