Physics engine

[vastrolorde]

Im thinking about trying to write some basic physics engine. Do games have a single physics engine instance that controls all the physics in the game, or are there multiple instances, so that it could be run on multiple threads and to speed up the calculations.

It may be possible for a single engine to run in multiple threads, depending on the kind of operations it performs.
Running multiple instances of an engine would be unusual because it would increase the memory consumption and physics objects handled by different instances would be unable to interact with each other.

OK ty. So i just have to dispatch worker threads if i need multi threading.
