resources.load(`prefabs/fruit${randomType}`, (err, prefab: Prefab) => {
if (err) {
console.error("失败", err); return;
}
const newFruit = instantiate(prefab);
newFruit.setPosition(this.spawnPoint!.position);
this.fruitContainer.addChild(newFruit);
const rigidBody = newFruit.getComponent(RigidBody2D);
if (rigidBody) rigidBody.enabled = false;
this._currentFruit = newFruit;
this.setupTouchControl(newFruit,this.cmq);
});
}
setupTouchControl(fruitNode: Node,cmq:Node) {
//fruitNode
fruitNode.on(Node.EventType.TOUCH_START, () => {
console.log("开始拖动");
});
fruitNode.on(Node.EventType.TOUCH_END, () => {
const rigidBody =fruitNode.getComponent(RigidBody2D);
if (rigidBody) rigidBody.enabled = true;
this._currentFruit = null;
this.scheduleOnce(() => this.generateNewFruit(), 1.0);
})
}
}就是 setupTouchControl这里如果是fruitNode.on(Node.EventType.TOUCH_END, () => 也就是fruitNode在前面那么代码可以运行,但是如果是我创建的cmq，cmq.on(Node.EventType.TOUCH_END, () => 就不行，我只改了这里，cmq是空节点，添加了boxcollider2D组件，问了ai也找不到原因，为什么不行？版本3.8.7
