统一获取错误 GameObject.GetComponent()

Question

我正在使用这个 tutorial 为我的游戏统一开发观察者模式。这里是 Observer class:

 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，当我想要运行这个时，它给了我这个错误：

error CS0411: The type arguments for method 'GameObject.GetComponent()' cannot be inferred from the usage. Try specifying the type arguments explicitly.

错误在这一行：

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

有什么方法可以修复这个错误吗？

您需要在您的案例中添加模板参数

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