没搞懂rotation与angle，rotation既然是个四元素，可面板上的是什么Vec3的方式显示，而且发现旋转节点，哪怕单独的旋转y轴，有时候三个值也会发生变化，猜测可能引擎内部是按照一定的规则，来表示这个旋转的形式，可能按照x,y,z或者x,z,y这样，来改变每个值的不同，实现这个旋转。
console.log(this.node.children[0].position);
console.log(this.node.children[0].worldPosition);
console.log(this.node.children[0].scale);
this.node.children[0].setScale(v3(2, 2, 2));
console.log(this.node.children[0].worldScale);
console.log(this.node.children[0].angle);
console.log(this.node.children[0].rotation);
//rotation转euler
this.node.children[0].setRotationFromEuler(0, 60, 0);
this.node.children[0].setWorldRotationFromEuler(0, 60, 0);
console.log(this.node.children[0].angle);
console.log(this.node.children[0].rotation);最新的api，好像要提出systemEvent这个全局单例了。
需要一个预制体，预制体[其他也差不多]，声明或者脚本中使用的一些小小的写法，一些判断，允许空，但是需要做一些处理。
@property(Prefab)
plane: Prefab = null!;
// plane: Prefab | null = null;
// plane: Prefab = null as unknown as Prefab;this.node?.addChild(plane);下面是一些事件的调试，已经加载预制体的两种方式，界面挂载与动态加载
//事件监听
//系统事件 全局单例模式的 systemEvent SystemEvent
//小写的是实例，大写的是这个类 on emit off
// [Scene] 'systemEvent' is deprecated since v3.4.0, please use 'input' instead.
systemEvent.on(SystemEvent.EventType.TOUCH_START, this._onTouchStart, this);
systemEvent.on(SystemEvent.EventType.TOUCH_MOVE, this._onTouchMove, this);
// systemEvent.on(SystemEvent.EventType.TOUCH_CANCEL, this._onTouchCancel, this);

input.on(Input.EventType.TOUCH_START, this._onInputTouchStart, this);
input.on(Input.EventType.KEY_UP, this._onInputkeyUp, this);
//重力感应
input.on(Input.EventType.DEVICEMOTION, this._DeviceMotion, this);
const plane: Node = instantiate(this.plane);
plane.parent = this.node;
plane.setPosition(0, 2, 0);
//loadDir<T extends Asset>(dir: string, onComplete?: ((err: Error | null, data: T[]) => void) | null): void;
resources.loadDir("plane01", (err: Error | null, data: Asset[]) => {if (err) {console.log("加载资源错误");}data.forEach(element => {if (element instanceof Prefab) {const plane: Node = instantiate(element);this.node?.addChild(plane);// plane.setParent(this.node);}});

//释放事件
protected onDestroy(): void {//估计要移除systemEvent这个组件实例了// systemEvent.off(SystemEvent.EventType.TOUCH_START, this._onTouchStart, this);input.off(Input.EventType.TOUCH_START, this._onInputTouchStart, this);// input.off(Input.EventType.TOUCH_START);
