Getting acces to SystemState in a method in an ISystem

[gritty beacon]

Trying to experiment a bit with a few ideas but is there a way in an ISystem to access the ref to the SystemState ? Like to disable the system OUTSIDE of a generic method with the ref in parameters ?

Example :
translating this method from a system base to a ISystem

private void EnableSelf()
{ 
   Enabled = true; <== this is what i'm trying to access
}

Basically trying to do this :

public void OnUpdate(ref SystemState state)
{
   state.Enabled = true;
}

Outide of the predetermine OnXXX Methods ( for whatever reasons )

if you are doing this for actual app logic - don't. This is only worth for debugging or some extremely hacky solutions, you couldn't solve otherwise.
But to do it you var sysHandle = World.GetExistingSystem<T>()
and then use World.Unmanaged.ResolveSystemState(sysHandle)
All of it is really slow and absolutely not suitable for game logic

Shit, so no way of doing as simple as for the system base.

neither you should do it for system base

this is extremely anti-ecs

Yeah I know. As I say it's mostly to experiment nothing else.

I'm looking at way to reduce boilerplating in some cases

Thanks for the answer.

best alternative - use RequireForUpdate

Do you have a resource for some good pattern for ecs ?

[gritty beacon]

yeah that I know, and then create an entity of a signletong with that

and then simply by existance of entity with component (or specific query) you can declare what systems run, without even knowing them

[gritty beacon]

yep

I know a couple of russian-speaking ones. It's pretty good even as auto-translated.
