1.UIManager函数定义

bool isGameUIManager;

UIPanelType currentGamePanel;

2.建立字典Dictionary<UIPanelType,BasePanel> UIPanelDict;

构造UIManager时，实例化UIPanelDict=new Dictionary<UIPanelType,BasePanel>();

3.当切换菜单场景和游戏场景时，需要清空字典

ClearDict(){

foreach(var item in UIPanelDict)

{

item.Value.Dispose();}

UIPanelDict.Clear();

}

4.创建GameUIManager和MainUIManager函数，

public void MainUIManager（）{

isGameUIManager=false;

if(UIPanelDict.Count!=0){

ClearDict();}

UIPanelDict.Add(UIPanelType.MainPanel,newMainPanel("Panel_Main",UIPanelType.MainPanel,this));

UIPanelDict.Add(UIPanelType.GamePanel,new GamePanel("Panel_Game",UIPanelType.GamePanel,this));

UIPanelDict.Add(UIPanelType.HelpPanel,new HelpPanel("Panel_Help",UIPanelType.HelpPanel,this));

UIPanelDict.Add(UIPanelType.SetPanel,new SetPanel("Panel_Set",UIPanelType.SetPanel,this));

UIPanelDict[UIPanelType.MainPanel].Show();

}

5.GameManager构建UImanager时调用MainUIManager。
