试了官方的热更新功能总结一下 主要用于安卓包热更新
参考 Cocos Creator 2.2.2 热更新简易教程 基于cocos creator2.4.x的热更笔记 二、使用软件 1、cocos creator v2.4.10
2、creator热更新插件热更新manifest生成工具creator应用商店下载 cocos提供的脚本也可以用但这个集成好了更便捷
3、静态资源服务器用的wintomcat tomcat下载安装
4、模拟器
5、Android打包环境
三、配置热更新
1、首先确保项目可以正常构建出apk进行一次构建 2、商城下载插件安装好 3、配置好地址只支持一个固定的地址对应服务器存放热更新文件的文件夹 4、点击生成热更新包再点击导入manifest
2.4.10控制台会提示xx已弃用建议使用xx按照提示全局搜索替换即可
5、把下面的脚本放在加载界面

}
本来还要在build\jsb-default\main.js开头添加热更新代码插件集成好了省略这一步
6、点击编译导出apk安装在手机上 原始含有热更新功能的包就打包好了
7、修改一部分内容再次构建只需要构建 然后在热更新工具把版本号增加一位点击生成热更包
将导出的压缩包放到服务器解压 手机上打开之前安装的包就会自动更新成最新版本
