        }
    }
}

创建委托类

public delegate void CallBack();//无参委托
public delegate void CallBack<T>(T arg1);//一个参数委托
public delegate void CallBack<T,X>(T arg1,X arg2);
public delegate void CallBack<T,X,Y>(T arg1, X arg2, Y arg3);
public delegate void CallBack<T,X,Y,Z>(T arg1, X arg2, Y arg3,Z arg4);
public delegate void CallBack<T,X,Y,Z,W>(T arg1, X arg2, Y arg3, Z arg4,W arg5);

创建事件码类

public enum EventType
{
    ShowText,
}

在需要监听的地方加监听方法

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

public class ShowText : MonoBehaviour
{

    private void Awake()
    {
        gameObject.SetActive(false);
      //  EventCreat.AddListener<string,>(EventType.ShowText, Show);
        EventCreat.AddListener<string,string,float,int,int>(EventType.ShowText,Show);
    }
    private void OnDestroy()
    {
       // EventCreat.RemoveListener<string>(EventType.ShowText, Show);
        EventCreat.RemoveListener<string,string,float,int,int>(EventType.ShowText, Show);
    }

    //private void Show(string str)
    //{
    //    gameObject.SetActive(true);
    //    GetComponent<Text>().text = str;
    //}
    private void Show(string str,string s,float f,int a,int b)
    {
        gameObject.SetActive(true);
        GetComponent<Text>().text = str+s+f+a+b;
    }
}

广播

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

public class BtnClick : MonoBehaviour
{
    private void Awake()
    {
        GetComponent<Button>().onClick.AddListener(() =>
        {
            // EventCreat.BroadCast(EventType.ShowText, "你好!");
            EventCreat.BroadCast(EventType.ShowText, "你好","呀！",1.0f,125,3);
        }); 
    }

}
