问题

我正在跟随一个教程，但当我保存Unity工程时，由于错误，无法测试我的工作。完整的错误信息是：“Assets\scripts\VidaPlayer.cs(25,34): error CS0117: 'Rigidbody2D' does not contain a definition for 'Static'”。它只在Unity中检测到错误，在Visual Studio中不显示任何错误。

这是我写的脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class LifePlayer : MonoBehaviour
{
    private Animator anim;
    private Rigidbody2D rb;

    private void Start()
    {
         anim= GetComponent<Animator>(); 
         rb= GetComponent<Rigidbody2D>();
    }

     private void OnCollisionEnter2D(Collision2D collision) 
     {
         if (collision.gameObject.CompareTag("Trap"))
         {
            Death();
         }
     }

     private void Death()
     {
          rb.bodyType = Rigidbody2DType2D.Static;//<-- 这里显示错误
          anim.SetTrigger("death");
     }
}

我尝试删除与rb相关的所有内容，但它显示这个错误：

im following a [tutorial](https://www.youtube.com/watch?v=ynH51MiKutY&amp;list=PLrnPJCHvNZuCVTz6lvhR81nnaf1a-b67U&amp;index=8) and when i saved the Unity Engine didnt allow me to test my work because of an error. the full error says &quot;Assets\scripts\VidaPlayer.cs(25,34): error CS0117: &#39;Rigidbody2D&#39; does not contain a definition for &#39;Static&#39; &quot;.  It only detects the error on unity, in VS Studio doesnt show any error.

This is the script that i wrote:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class LifePlayer : MonoBehaviour
{
private Animator anim;
private Rigidbody2D rb;

private void Start()
{
     anim= GetComponent<Animator>(); 
     rb= GetComponent<Rigidbody2D>();
}

 private void OnCollisionEnter2D(Collision2D collision) 
 {
     if (collision.gameObject.CompareTag("Trap"))
     {
        Death();
     }
 }

 private void Death()
 {
      rb.bodyType = Rigidbody2D.Static;//<-- where it shows the error
      anim.SetTrigger("death");
 }

}

i tried to remove all that is involved with the rb but it show me this error :

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.Graphs.Edge.WakeUp () (at <8e8a32ebae4d4c768ca69b7e552734c1>:0)

代码部分不要翻译。以下是翻译好的内容：

"everything seems working fine in the code, Try exiting and restarting Unity if you open the player animator you will notice that it have disappeared this is a bug in unity
try restarting unity it should work again as intended"

在代码中：

将以下行：

rb.bodyType = Rigidbody2D.Static;//&lt;-- where it shows the error

更改为：

rb.bodyType = RigidbodyType2D.Static;

Simple small typo

in Code :

    rb.bodyType = Rigidbody2D.Static;//&lt;-- where it shows the error

change to:

rb.bodyType = Rigidbody**Type**2D.Static;
