unity鼠标悬停在Button上显示介绍

鼠标停在按钮上，会显示详情介绍提示框，代码如下;

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

/// 

/// 鼠标悬停于按钮上显示介绍的基类
/// 
public class BtnHoverBase : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
	/// 

	/// 鼠标移动到按钮上显示的东西
	/// 
	public GameObject tipsBg { get; set; }
	public Text textTips { get; set; }

	private void Awake()
	{
		tipsBg = transform.GetChild(0).gameObject;
		textTips = tipsBg.transform.GetChild(0).GetComponent();
	}

	public void SetValue(string text)
	{
		textTips.text = text;
	}

	public void OnPointerEnter(PointerEventData eventData)
	{
		tipsBg.SetActive(true);
	}

	public void OnPointerExit(PointerEventData eventData)
	{
		tipsBg.SetActive(false);
	}
}

这是基类，可以写一个子类代码继承这个基类，设置具体信息，把基类中的Awake()方法删掉，在子类中编写，代码拖给需要显示信息的按钮上，代码如下：

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

/// 

/// 鼠标移动到按钮上显示介绍
/// 
public class TestButton : BtnHoverBase
{


	private void Awake()
	{
		tipsBg = transform.GetChild(0).gameObject;
		textTips = tipsBg.transform.GetChild(0).GetComponent();


		textTips.text = "仙剑奇侠传";
	}
}
