[LayaAirIDE 1.0]官方DynamicBatchTest照做为什么动态合不了批？

class DynamicBatchTest {
constructor() {
Laya3D.init(0, 0);
Laya.stage.scaleMode = Laya.Stage.SCALE_FULL;
Laya.stage.screenMode = Laya.Stage.SCREEN_NONE;

var camera = scene.addChild(new Laya.Camera(0, 0.1, 1000));
camera.transform.translate(new Laya.Vector3(0, 6.2, 10.5));
camera.transform.rotate(new Laya.Vector3(-40, 0, 0), true, false);
camera.addComponent(CameraMoveScript);
