import {
  createWorld,
  Types,
  defineComponent,
  defineQuery,
  addEntity,
  addComponent,
  pipe,
} from 'bitecs'

const Vector3 = { x: Types.f32, y: Types.f32, z: Types.f32 }
const Position = defineComponent(Vector3)
const Velocity = defineComponent(Vector3)

const movementQuery = defineQuery([Position, Velocity])

const movementSystem = (world) => {
  const { time: { delta } } = world
  const ents = movementQuery(world)
  for (let i = 0; i < ents.length; i++) {
    const eid = ents[i]
    Position.x[eid] += Velocity.x[eid] * delta
    Position.y[eid] += Velocity.y[eid] * delta
    Position.z[eid] += Velocity.z[eid] * delta
  }
  return world
}

const timeSystem = world => {
  const { time } = world
  const now = performance.now()
  const delta = now - time.then
  time.delta = delta
  time.elapsed += delta
  time.then = now
  return world
}

const pipeline = pipe(movementSystem, timeSystem)

const world = createWorld()
world.time = { delta: 0, elapsed: 0, then: performance.now() }

const eid = addEntity(world)
addComponent(world, Position, eid)
addComponent(world, Velocity, eid)
Velocity.x[eid] = 1.23
Velocity.y[eid] = 1.23

setInterval(() => {
  pipeline(world)
}, 16)
