游戏开发中的资源加载是少不了的，封装一个资源管理可以更加方便的使用

脚本名 ResourceManager.js

var ResourceManager = function(){
    
};

ResourceManager.m_atlasDic = null;

//加载主要界面
ResourceManager.LoadWindow = function(mName,LoadPrefabComplete){
    window.cc.loader.loadRes( window.Constant.RootPath.WIND_ROOT_PATH + mName +"/" + mName,LoadPrefabComplete);
},
//加载预制体
ResourceManager.LoadPrefab = function(path,LoadPrefabComplete){
    window.cc.loader.loadRes(path,LoadPrefabComplete);
},
//加载图集
ResourceManager.LoadAtlasA = function(rootPath,atlasName)
{
    let atlasPath = rootPath + atlasName;
    window.cc.loader.loadRes(atlasPath,cc.SpriteAtlas,function(error,list){
        let spriteFrames = null;
        if(error){
            console.log("loadAtlas Error : "+atlasPath);
        }
        else
        {
            if(null == ResourceManager.m_atlasDic) ResourceManager.m_atlasDic = new window.dictionary(); 
            spriteFrames = list.getSpriteFrames();
            ResourceManager.m_atlasDic.add(atlasName,spriteFrames);
        }
    });
},
//加载图集
ResourceManager.LoadAtlas = function(atlasName,spriteObj,spriteName){
