Called to render the node using the provided renderer.

​
pointerDown

Pointer event down handler. 
function handlePointerDown(self: MyGame, event: PointerEvent)
  print('Pointer Position: ', event.position.x, event.position.y)

  event:hit()
end

return function(): Node<MyGame>
    return {
        init = init,
        advance = advance,
        draw = draw,
        pointerDown = handlePointerDown,
    }
end

​
pointerMove

Pointer event move handler. 
function handlePointerMove(self: MyGame, event: PointerEvent)
  print('Pointer Position: ', event.position.x, event.position.y)

  event:hit()
end

return function(): Node<MyGame>
    return {
        init = init,
        advance = advance,
        draw = draw,
        pointerMove = handlePointerMove,
    }
end

​
pointerUp

Pointer event up handler. 
function handlePointerUp(self: MyGame, event: PointerEvent)
  print('Pointer Position: ', event.position.x, event.position.y)

  event:hit()
end

return function(): Node<MyGame>
    return {
        init = init,
        advance = advance,
        draw = draw,
        pointerUp = handlePointerUp,
    }
end

​
pointerExit

Pointer event exit handler. 
function handlePointerExit(self: MyGame, event: PointerEvent)
  print('Pointer Position: ', event.position.x, event.position.y)

  event:hit()
end

return function(): Node<MyGame>
    return {
        init = init,
        advance = advance,
        draw = draw,
        pointerExit = handlePointerExit,
