Function Systems

[robertlong]

Just an idea, not sure if it's a good one yet. If systems are supposed to be stateless, it may be a good idea to make them a function.

function RotateObjectsSystem(world, queries) {
  const { dt } = queries.clock[0].getComponent(Clock);

  queries.entities.forEach((entity) => {
    
    const rotateX = entity.getComponent(RotateX);
    const transform = entity.getComponent(Transform);

    transform.rotation.x += rotate.speed * dt;
  });
}

RotateObjectsSystem.query = {
  clock: { components: [Clock]},
  entities: { components: [Transform, RotateX] }
};

Seems like React stateless component. 😆
