Major Changes

• 8a7a315: - The library has been significantly simplified and an almost mind-boggling number of bugs have beens quashed.

  • The main import and initialization have changed:

    import { World } from "miniplex"
    import createReactAPI from "miniplex-react" // !
    
    /* It now expects a world as its argument, so you need to create one first: */
    const world = new World()
    const ECS = createReactAPI(world)

  • All lists of entities are now rendered through the upgraded <Entities> component, which takes an array of entities or a query (or even a world) as its in prop:

    <Entities in={world.with("asteroid")}>{/* ... */}</Entities>

    If you're passing in a query or a world, the component will automatically re-render when the entities appear or disappear. If you don't want this, you can also just pass in a plain array containing entities:

    <Entities in={[entity1, entity2]}>{/* ... */}</Entities>

  • <ManagedEntities> has been removed. You were probably not using it. If you were, you can replicate the same behavior using a combination of the <Entities> component and a useEffect hook.

  • The useEntity hook has been renamed to useCurrentEntity.

  • The world-scoped useArchetype hook has been removed, and superseded by the new global useEntities hook:

    /* Before */
    const entities = useArchetype("position", "velocity")
    
    /* Now */
    const entities = useEntities(world.with("position", "velocity"))
