前言：游戏上线后，我们常常还会需要更新，如新增玩法，活动等，这种动态的更新资源我们称为游戏的热更新。热更新一般只适用于脚本语言，因为脚本不需要编译，是一种解释性语言，而如C++语言是很难热更新的，其代码只要有改动就需要重新链接编译(接口统一，用动态库可以实现，不过太不灵活了)。 热更新基本思路
热更新注意点
--创建可写目录与设置搜索路径
self.writeRootPath = cc.FileUtils:getInstance():getWritablePath() .. "_ClientGame2015_"
if not (cc.FileUtils:isDirectoryExist(self.writeRootPath)) then
cc.FileUtils:createDirectory(self.writeRootPath)
end
local searchPaths = cc.FileUtils:getSearchPaths()
table.insert(searchPaths,1,self.writeRootPath .. '/')
table.insert(searchPaths,102);">2,0);">'/res/')
table.insert(searchPaths,102);">3,0);">'/src/')
cc.FileUtils:setSearchPaths(searchPaths)
热更新源代码分为逻辑层与UI层，UI层是异步加载的，所以不能把这个模块当场景切换，用addChild添加到已有场景上就是。 逻辑层： require('common.json')
local UpdateLogicLayer = class("UpdateLogicLayer",cc.Node)
function UpdateLogicLayer:create(callback)
local view = UpdateLogicLayer.new()
local function onNodeEvent(eventType)
if eventType == "enter" then
view:onEnter()
elseif eventType == "exit" then
view:onExit()
end
end
view:registerScriptHandler(onNodeEvent)
view:init(callback)
return view
end
function UpdateLogicLayer:ctor()
self.writeRootPath = nil --手机可写路径
self.manifest = nil --配置表信息(json->table)
self.resConfigInfo = nil --资源列表(json->table)
self.updateResTable = nil --需要更新资源表
self.updateResProgress =1 --更新进度
self.updateResPath = nil --当前更新资源路径
self.EventType = {
None = 0,--初始化状态
StartGame = --开始游戏
StartUpdate = --开始更新
AssetsProgress = --资源更新中
AssetsFinish = 4,0);">--资源更新完成
}
self.callback = nil --外部回调
self.status = self.EventType.None
function UpdateLogicLayer:onEnter()
function UpdateLogicLayer:onExit()
function UpdateLogicLayer:init(callback)
self.callback = callback
--创建可写目录与设置搜索路径
self.writeRootPath = cc.FileUtils:getInstance():getWritablePath() .. if not (cc.FileUtils:getInstance():isDirectoryExist(self.writeRootPath)) then
cc.FileUtils:getInstance():createDirectory(self.writeRootPath)
end
local searchPaths = cc.FileUtils:getInstance():getSearchPaths()
table.insert(searchPaths,self.writeRootPath .. '/src/')
cc.FileUtils:getInstance():setSearchPaths(searchPaths)
--配置信息初始化

UI层： --[[ 说明： 1，本地需求配置文件：project.manifest,resConfig.json 2，循环post请求，有时会出现闪退情况，最好改成只发一次zip压缩包形式 3，目前只支持ios，lua io库文件操作在andriod上不行，文件操作c实现(注意lua与c++交互对于char *遇/0结束问题，需要改lua绑定代码) ]]
