统一获得错误GameObject.GetComponent（）

Question

我正在使用此tutorial为我的游戏开发统一的观察者模式。这是Observer类：

 using UnityEngine;
 using System.Collections;

 namespace ObserverPattern
 {
     //Wants to know when another object does something interesting 
     public abstract class Observer 
     {
         public abstract void OnNotify();
     }

     public class Box : Observer
     {
         //The box gameobject which will do something
         GameObject boxObj;
         //What will happen when this box gets an event
         BoxEvents boxEvent;

         public Box(GameObject boxObj, BoxEvents boxEvent)
         {
             this.boxObj = boxObj;
             this.boxEvent = boxEvent;
         }

         //What the box will do if the event fits it (will always fit but you will probably change that on your own)
         public override void OnNotify()
         {
             Jump(boxEvent.GetJumpForce());
         }

         //The box will always jump in this case
         void Jump(float jumpForce)
         {
             //If the box is close to the ground
             if (boxObj.transform.position.y < 0.55f)
             {
                 boxObj.GetComponent().AddForce(Vector3.up * jumpForce);
             }
         }
     }
 }

但是，当我要运行它时，出现此错误：

错误CS0411：无法从用法中推断出方法'GameObject.GetComponent（）'的类型参数。尝试显式指定类型参数。

错误在此行上：

boxObj.GetComponent().AddForce(Vector3.up * jumpForce);

有什么办法可以纠正此错误？

提前感谢

您需要在这种情况下添加模板化参数

boxObj.GetComponent<Rigidbody>().AddForce(Vector3.up * jumpForce);
