请问unity按钮注册了鼠标点击事件，但为什么运行的时候点不动呢
```c#
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PausePanel : MonoBehaviour
{
private Animator anim;
public GameObject button;
private void Awake()
{
anim = GetComponent<Animator>();
}
public void Retry()
{
}
///<summary>
///点击了pause按钮
///</summary>
public void Pause()
{
//播放pause动画
anim.SetBool("isPause", true);
button.SetActive(false);
}
/// <summary>
/// 点击了继续按钮
/// </summary>
public void Resume()
{
//播放resume动画
Time.timeScale = 1;
anim.SetBool("isPause", false);
}
public void Home()
{
}
/// <summary>
/// pause动画播放完调用
/// </summary>
public void PauseAnimEnd()
{
Time.timeScale = 0;
}
/// <summary>
/// resume动画播放完调用
/// </summary>
public void ResumeAnimEnd()
{
button.SetActive(true);
}
}
```
