Add a Lyra-like Global Ability Subystem

[LeoFabre]

Lyra has a Global Ability System that keeps track of all ASCs in a level.

It's useful because you can use it to grant/activate abilities and effects to all players at once, for example.

I will need that in my game at some point, so if I end up making it, I'll be happy to contribute it there.

Cheers !

I suppose I could see this as a subsystem. I'm having trouble thinking of actual uses for, but also don't have anything against it.

Lyra's docs have a few use-case examples :

For example, Lyra's Elimination mode applies a Gameplay Effect (GE_PregameLobby) globally during the warm-up phase of a match. It grants a damage immunity tag to all players and triggers a Gameplay Cue that enables a UI element indicating that the match hasn't started yet.

@LeoFabre Looking at the implementation in Lyra, there isn't an actual global ASC, just the subsystem that is responsible for orchestrating abilities and effects on registered ASCs. Have you found that not possible to do with GMAS? I don't know either way yet but i'm curious if you've tried to integrate GMAS component on the GameState or have run into any other problems. I'm still in the process of determining what I can port from Lyra to a new project using GMC + GMAS.

Yes I am talking about a subsystem, not a global ASC.

Also, as said, I am not needing it right now, so IDK if actually possible to do with GMAS but looking at it there should not be any major problems adding this.

If you are talking of the ASC that is used in lyra's gamestate for the Gameplay Phases Abilities, this is a slightly different use case of an ASC than what GMAS was originally made for, but on the top of my head it should be doable.
Alternatively, you could have GMAS for your gameplay abilities, and GAS just for the game state stuff. Though, obviously you will have to replace the uses of GAS functions and GAs and of the global ability subsystem in your phases.

Sorry for the delay, I'm quite busy these days.
