Duplicated World Systems not appearing inside Debugger

Hello,
trying to duplicate a world with more advanced code and even the simplest like this one

Code (CSharp):

1. DefaultWorldInitialization.Initialize("World 1", editorWorld: false);
2. World w2 = new World("World 2");
3. foreach (var system in World.Active.Systems)
4. {
5.   w2.CreateSystem(system.GetType());
6. }

all systems always only appear in one world.



Using ScriptBehaviourUpdateOrder.UpdatePlayerLoop typically only shows the system in the world last called with it.

World.Active.Systems.Count() and the same for w2 are showing, that they have systems (World.Active has 26 and w2 has somehow 33).

Is there any chance to get both worlds active inside the entity debugger?

 

You using old way of adding different world. Read here:
https://docs.unity3d.com/Packages/com.unity.entities@0.0/manual/system_update_order.html

Also look here:
https://forum.unity.com/threads/are-custom-worlds-broken-or-no-longer-supported.649759/#post-4445473

TL;DR
Systems created in other world should be added to one of default world groups (sample in second link) and after that you should refresh systems order for that group.

 

Thanks for your answer.
Unfortunately those docs didn't help as it seems that there are some quirks to get all the systems of the default world to run in more than one world at the same time.

Still I got it to work for my testing environment together with a customized ConvertToEntity script.
