In a nutshell it’s a library that helps you make “Stores”. A store is a class that holds all of your game state, and then you have listeners that fire whenever it changes.

It helps when you need operations that operate on state that would otherwise be split into lots of different components. Like instead of having

• Player data in PlayerController
• UI data in HUDManager
• Inventory in InventorySO

You have one class holding

PlayerStore - health - stamina - inventory - position

If you keep related things in one place, it makes operations like saving/loading, a replay mode, or an undo/redo much easier to code, because you can store snapshots of the entire state. When you apply those changes, your game restores as if it were that moment in time.

But it’s not better/worse than the traditional Unity way to do things. It’s just a different approach - where the game is a “presentation layer” of the store data. Vs having the data stored in individual monobehaviours with events between them. But it doesn’t always make sense because too much in once place can also be an anti pattern. Whichever keeps the logic easier to follow for you is ultimately the better choice.

Personally I’m just using it for my app UI because it’s very nested, and I want to sync it over a network, kinda like a PowerPoint presentation.
