lua语言作为一门轻量级脚本语言，能够非常好的被嵌入到应用程序，因此，在移动游戏开发中举足轻重

然后C/C++开发人员转lua并非非常习惯，我也是。。所以，一起努力学习lua吧

lua没有类的概念，有table的概念

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">function create(name,id) </span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">   local obj={name = name ,id = id}</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">   function obj:setName(name)</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">      self.name=name</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">   end</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">   function obj:setID(id)</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">      self.id=id</span>

<span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240);">   end</span>

end

lua能够用继承的概念

--基类

function createRobot(name,id)

   local obj={name =name, id= id}

   function obj:setName(name)

        self.name=name

   end 

   function obj:getName()

        return self.name

   end

   function obj:setID(id)

        self.id=id

   end

   function obj:getID()

        return self.id

   end

   return obj

end

--派生类

function createFootballRobot(name,id,position)

   local obj=createRobot(name,id)

   obj.position="right"

   return obj

end
