Reduxity

Redux + Unity. Provides a bare-bones state management container inspired by Redux.

Redux is heavily used in web development. Is this pattern a good fit for game state? Probably not in most cases, but the experiment is ongoing.

Using

Define a state object:

struct GameState
{
    public Vector3Int playerPosition;
}

Add actions to affect the state:

interface IGameAction {}

struct MoveAction : IGameAction
{
    public Vector3Int direction;
}

Create a reducer to update the state when an action is dispatched:

static GameState Reducer(GameState state, IGameAction action)
{
    switch (action)
    {
        case MoveAction moveAction:
            state.playerPosition += moveAction.direction;
            return state;

        default:
            return state;
    }
}

Tie it all together with a store:

Store<GameState, IGameAction> store = new(Reducer);

Dispatch changes:

store.Dispatch(new MoveAction { direction = Vector3Int.up });

Subscribe to changes:

store.changed += _ => Debug.Log($"New position: {store.state.playerPosition}");
