回旋镖 (U7)

一如既往，这是代码：

namespace Boomerang { // 物品模块会为物品对象添加一个Unity组件。更多信息请参阅Unity MonoBehaviour：https://docs.unity3d.com/ScriptReference/MonoBehaviour.html // 当触发器被按下时，该组件会对玩家刚体施加一个朝向物品变换方向的力（参见物品预制体中物品定义组件的自定义引用） public class ItemBoomerang : MonoBehaviour { protected Item item; private Transform boomerangTransform; private Transform headTransform;
