Why [DisableAutoCreation] is not working on a base class?

Hello,

I want to create my systems manually, but adding [DisableAutoCreation] attribute on every class I want to manually initialize is a bit of a pain, because it's mostly all of them. Hence I created a base class "BaseManualSystem", which contains this attribute, and systems which should be not created automatically, I would just inherit from this base class.

Is there any reason why I can't use this attribute on a base class? I get this warning, and my class is initialited anyway: {Invalid [DisableAutoCreation] on BaseManualSystem (only concrete types can be instantiated)}.

Thanks in advance.

 

ICustomBootstrap.cs has been changed recently, which means if it executes, Unity doesn't put it's default systems in. I wanted to predefine a filter that Unity wouldn't initialize my systems automatically, but now I cannot, unless I put [DisableAutoCreation] flag on every system. That's every single system in my game.

I'd like Unity's default loop with my systems initialized whenever I want them to.

If the circled value was "true", it would allow inheritance @Unity. Of course it would still print out that Debug.LogWarning(). Should just skip it silently, I think.


Help please?
