根据教程弄了一个新项目，把app.js放在服务端，内容是一个helloWord场景。 如果下载成功会自动运行。 配置好服务端的下载url了，就是AssetsManager下载提示UPDATE_FINISHED之后，loadGame()的时候没有成功加载jsList。 找不到下载的js目录文件（我命名为newPath)的路径， 程序跑到loadJs 却没有跑进去。
代码如下：
//------------------------- 本地 project.manifest ----------------
{
“packageUrl” : “http://xxx.xxx.com/”,
“remoteManifestUrl” : “http://xxx.xxx.com/project.manifest”,
“remoteVersionUrl” : “http://xxx.xxx.com/version.manifest”,
“version” : “1.0.1”,
“engineVersion” : “cocos2d-x-3.7”,
“assets” : { },
“searchPaths” : []
}
//------------------------- project.manifest ----------------
{
“packageUrl” : “http://xxx.xxx.com/”,
“remoteManifestUrl” : “http://xxx.xxx.com/project.manifest”,
“remoteVersionUrl” : “http://xxx.xxx.com/version.manifest”,
“version” : “1.0.2”,
“engineVersion” : “cocos2d-x-3.7”,
“assets” : {
“hotFix.zip” : {
“compressed” : true
}
},
“searchPaths” : [ ]
}
//------------------------- version.manifest ----------------
{
“packageUrl” : “http://xxx.xxx.com/”,
