Question

首先，我知道我应该在Unity论坛上提出这个问题，但我已经问了两次，没有人有答案。

现在有了这个，这是我为拾取和保存对象而编写的代码。我的问题是，现在每当我尝试拿起一个物体时，它就会直接进入掉落动作。我认为问题始于void Update中第42行的if语句。

感谢任何帮助。

 void ItemPickUp(GameObject objectToPickup) {
    // unless you've set your LayerMask to only hit the objects that can be picked up (you should do this as well, for optimization purposes), you must check if you can pick up this object

            return;

        CarriedObject.transform.position = Camera.main.transform.position + Camera.main.transform.forward * OffsetDropPosition;

在export class AdpDetailPage{ constructor(public navParams: NavParams){ errorEvent = this.navParams.get('errorEvent'); console.log("errorEvent= ", errorEvent); } }类中创建一个私有变量careAboutInput，并将其用作PickUp函数中的开关：

Update

尝试执行操作会直接跳到另一个操作
