从 creator热更新问题 继续讨论：
Creator v1.9.3热更新
新版本生成 具体步骤：
-
先创建新版本，具体如下图，多了一个新场景NewScene：
-
构建项目：
-
生成对比文件前要做的准备工作，首先你得先安装一下nodejs工具，我这里自己写了个批处理文件：
批处理代码：
version_generator.js 自己去官方的dome里面拿一个放在自己自己项目下面；
-v 1.7.0 这里是新版本的版本号，反正必须要比你的旧版本高；
-u http://112.74.42.214:8011/remote-assets-hotupdatetest/ 是你的热更服务器地址；
-s build/jsb-link/ 构建生成的项目路径；
-d assets/ 存放生成对比文件的路径。
------------------------------------------------------------------------------
4. 执行批处理文件 热更新.bat，成功以后你会发现项目assets/ 下面会有两个对比文件：project.manifest、version.manifest。
5. 把assets/ project.manifest拖入你UI界面上的ManifestUrl上，注意ManifestUrl的类型是raw-asset而不是官方Dome上的asset：
6. 保存，然后重新构建一次项目。
7. 构建完成后：
a) 把 build/jsb-link/ 路径下生成的 res 和 src 拷贝到你服务器(我这里就是http://112.74.42.214:8011/remote-assets-hotupdatetest/)更新路径下；
b) 把 assets/ 下生成的project.manifest、version.manifest 这两个文件一样拷贝到你的服务器更新路径下。
- 到这里新版本就做完了，更新服务器怎么搭建就不说了吧。
旧版本生成 具体步骤：
- 删掉build/jsb-link文件夹； 删除assets/ 下生成的project.manifest、version.manifest；删除场景NewScene以及对于代码和资源（随便你自己怎么弄，有明显UI变动就可以）：
- 构建项目，配置不要改动：
- 修改批处理代码中版本号 改成1.0.0，比你生成的新版本号低就好，然后执行批处理文件 热更新.bat，成功以后你会发现项目assets/ 下面会有两个对比文件：project.manifest、version.manifest。
- 把assets/ project.manifest拖入你UI界面上的ManifestUrl上，注意ManifestUrl的类型是raw-asset而不是官方Dome上的asset：
- 保存，然后重新构建一次项目。
- 构建完成后先不要编译，还有一个重要步骤。
修改main.js，添加本地热更新路径：
修改完保存。
7. 然后再编译(这里就不需要再去构建了，直接编译)
8. 编译没错误就OK了，我这里是android平台debug模式下：
更新前：
点击检查更新按钮：
发现有新版本了，然后点击开始更新：
发现正在下载更新文件。
更新完成重启后：
新版本这里我把更新界面的LOGO也换掉了的，
点击检查更新按钮：
发现没有新版本了，切换场景按钮就显示出来了，点击按钮跳转到NewScene，
更新代码：
