最终效果：
这是显示的文本
鼠标移上事件文字 “百鬼夜行” 后，控制台打印：
鼠标点击事件文字 “百鬼夜行” 后，控制台打印：
鼠标移出事件文字 “百鬼夜行” 后，控制台打印：

（二）：将上面的mTextPro.cs；挂载到一个ui物体上：
新建ProjectTest .cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ProjectTest : MonoBehaviour
{
public mTextPro textPic;
private void Start()
{
textPic.SetText("--这里显示的是当前选择的" + textPic.EventStrReplace + "任务", "百鬼夜行", "", mouseClick, mouseEnter, mouseExit);
}
private void mouseEnter()
{
Debug.Log("鼠标移入任务名称");
}
private void mouseExit()
{
Debug.Log("鼠标移出任务名称");
}
private void mouseClick()
{
print("鼠标点击了任务名称");
}
}
将该脚本挂载到任一物体上，把对象上赋值，运行项目进行测试
用鼠标进行事件文本的交互，就可以看到效果了：
ps：我是根据这位仁兄的文章改动的。
其他方式也可以实现此功能，我这是在网上找的相关博客自己总结的，如果哪位路过的大佬有更简单的实现，还望评论告知：多谢(抱拳)。
