开始场景——设置界面

step1：设置面板的背景图

照着这个来设置就行了

step2：写代码

关联的按钮控件

监听事件函数

注意：要在start函数中再写一行HideMe函数，以便该面板能在一开始就能隐藏自己。

再在BeginPanel脚本中调用该函数即可

然后在SettingPanel脚本中控制显隐

那么我们可以发现写UI的套路无非就三部：1.拼UI，2.在脚本中声明一系列public的GUI控件并在unity中进行拖拽关联，3.监听事件

直到当前SettingPanel和BeginPanel的代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;public class SettingPanel : BasePanel<SettingPanel>
{//关联的各按钮控件public CustomGUISlider sliderMusic;public CustomGUISlider sliderSound;public CustomGUIToggle toggleMusic;public CustomGUIToggle toggleSound;public CustomGUIButton btnExit;void Start(){//事件监听btnExit.clickEvent += () =>{HideMe();BeginPanle.Instance.ShowMe();};HideMe();}}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;public class BeginPanle : BasePanel<BeginPanle>
{//关联的各按钮控件public CustomGUIButton btnBegin;public CustomGUIButton btnSettings;public CustomGUIButton btnExit;public CustomGUIButton btnRank;void Start(){//事件监听btnBegin.clickEvent += () =>{SceneManager.LoadScene("GameScene");};btnSettings.clickEvent += () =>{   SettingPanel.Instance.ShowMe();HideMe();};btnExit.clickEvent += () =>{};btnRank.clickEvent += () =>{};}}
