Question by shirohige3001 · Dec 30, 2019 at 10:03 AM · dots

What happened to World.Active (ECS)?

In a tutorial

 World world = World.Active

is used to get the current simulation world. This was removed from the API somewhere around 0.12.

Now I'm using

 World world = World.AllWorlds[0];

but this just doesn't seem like it's the intended way.

So, what happened to World.Active?

I searched the changelogs but didn't find anything.

Thank you in advance.

I found it in the source code:

"World.Active has been deprecated. The most common & incorrect usage has been to use World.Active from a ComponentSystem. From a ComponentSystem you should use the ComponentSystem's World property directly. It returns the world that this system belongs to. There are some rare cases where a $$anonymous$$onoBehaviour needs to inject data into the active world, in this case use World.DefaultGameObjectInjectionWorld. (RemovedAfter 2020-01-22)"

TL;DR:

It's called World.DefaultGameObjectInjectionWorld now.


I still see it there but with annotation:

[Obsolete("World.Active has been deprecated. The most common & incorrect usage has been to use World.Active from a ComponentSystem. From a ComponentSystem you should use the ComponentSystem's World property directly. It returns the world that this system belongs to. There are some rare cases where a MonoBehaviour needs to inject data into the active world, in this case use World.DefaultGameObjectInjectionWorld. (RemovedAfter 2020-01-22)")]

So, it appears World.DefaultGameObjectInjectionWorld is what should be used in its place.
