/*NOTE: The Simulation behaves as if events during a turn happen simultaneous.
* That way the simulation is deterministic, even though (partial) events may
* occur in an arbitrary order. This is archived by applying types of event in
* a particular order. E.g. player movements never influence each other.
* Collisions never influence each other. But movement influences Collision.
* Therefor if movement and collision were interleaved, the order of events
* would matter. By splitting movement and collision, the order of events does
* not matter.
* If an event can influence events of its type, this system won’t work. One
* solution to this problem is to split the event in parts, that influence
* each other but not themselves.
