How to add systems to worlds different from default?

Unity Engine
1

Hello.

In my project i want to separate entities into worlds(world for characters and world for misc entities). Lets call them CharacterWorld and MiscWorld. As of now i figured out how to create new worlds, but not how to add systems to those worlds. Is there any way i can add systems to CharacterWorld and MiscWorld? And if yes, can they be updated simultaneously?

Thank you.

You use myCustomWorld.GetOrCreateSystem(systemType) to create the system to your custom world. To use SystemGroups and insert into PlayerLoops, refer here: Is there an update to framerated fixed physics?
