Luvit像Node.js一样写Lua应用
luvit是什么？它是目前Lua这个小众语言中较为流行的一个开源框架，给那些习惯使用Lua的开发者一个机会向写Node.js一样用Lua进行开发，它是Lua的Node.js.在Gitlab上，项目的描述对于Luvit是这样描述的：Lua + libUV + jIT = pure awesomesauce。

Lua界的Node.js
一个Node.js的HelloWorld的server.js可能是这样的，运行则是使用node server.js
var http = require('http');
http.createServer(function (req, res) {
var body = 'Hello world\n';
res.setHeader('Content-Type', 'text/plain');
res.setHeader('Content-Length', body.length);
res.end(body);
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
而Luvit的HelloWorld的Server.lua则是这样的，运行则是使用luvit server.lua
[root@kong ~]# cat server.lua
local http = require('http')
http.createServer(function (req, res)
local body = 'Hello world\n'
res:setHeader('Content-Type', 'text/plain')
res:setHeader("Content-Length", #body)
res:finish(body)
end):listen(1337, '127.0.0.1')
print('Server running at http://127.0.0.1:1337/')
[root@kong ~]#
运行结果为：
[root@kong ~]# luvit server.lua
Server running at http://127.0.0.1:1337/
确认结果：
[root@kong ~]# curl http://localhost:1337
Hello world
[root@kong ~]#

Lua游戏开发教程之时区问题详解
前言 什么是Lua? Lua 是一个小巧的脚本语言,巴西里约热内卢天主教大学里的一个研究小组于1993年开发,其设计目的是为了嵌入应用程序中,从而为应用程序提供灵活的扩展和定制功能.Lua由标准C编写而成,几乎在所有操作系统和平台上都可以编译,运行.一个完整的Lua解释器不过200k,在目前所有脚本引擎中,Lua的速度是最快的.这一切都决定了Lua是作为嵌入式脚本的最佳选择.相比Python和Per的内核,Lua的内核小于120KB,而Python的内核大约860KB,Perl的内核大约1.1M

Lua中三种循环语句的使用讲解
Lua的循环和C语言的循环的语法其实差不多,所以,理解起来就很好理解的啦,所以实现也很简单,跟C没什么两样,都差不多. 案例如下: test1.lua -- 1.while循环 --[[ 理解为C语言的就行了,其实差不多的 语法格式: while(true) do 执行语句 end ]] --定义一个全局变量a=0 a=0 -- while(true) do a=a+1 print("a:",a) if(a == 5) then break end end -- 2.for循环 --[

Lua中的变量与赋值方法
看以下案例: test.lua -- 第一个lua脚本 --注释使用"--"符 --变量未定义时,默认初始化的值为nil --这样的定义为全局 num1 = 1 ; --加了关键字local表示这个变量是局部变量 local num2 = 2 ; --定义变量的末尾不加分号;也是可以的,个人建议,因为Lua是C写的,写分号还是规范点 num3 = 3 --定义一个函数,目的是实现两数相加并返回 function add() --a = 1 也可以在函数内部定义 --b = 2 retu

Lua协同程序coroutine的简介及优缺点
什么是协同(coroutine)? Lua 协同程序(coroutine)与线程比较类似:拥有独立的堆栈,独立的局部变量,独立的指令指针,同时又与其它协同程序共享全局变量和其它大部分东西. 协同是非常强大的功能,但是用起来也很复杂. 线程和协同程序区别 协程是编译器级别的,线程是操作系统级别的,在多处理器情况下,多线程程序同时运行多个线程:而协同程序是通过协作来完成,在任一指定时刻只有一个协同程序在运行,并且这个正在运行的协同程序只在必要时才会被挂起.这样Lua的协程就不能利用现在多核技术了.

安装Nginx+Lua开发环境
首先我们选择使用OpenResty,其是由Nginx核心加很多第三方模块组成,其最大的亮点是默认集成了Lua开发环境,使得Nginx可以作为一个Web Server使用.借助于Nginx的事件驱动模型和非阻塞IO,可以实现高性能的Web应用程序.而且OpenResty提供了大量组件如Mysql.Redis.Memcached等等,使在Nginx上开发Web应用更方便更简单.目前在京东如实时价格.秒杀.动态服务.单品页.列表页等都在使用Nginx+Lua架构,其他公司如淘宝.去哪儿网等. 安装环境

lua开发中实现MVC框架的简单应用
先简单说说MVC,即Model View Controller.Model(模型),一般负责数据的处理:View(视图),一般负责界面的显示:Controller(控制器),一般负责前端的逻辑处理.拿一款手机游戏来说,界面UI的显示.布局等就是View负责:点击了按钮,手势的滑动等操作由Controller来处理:游戏中需要的数据资源就交给Model. 接下来,看看在游戏开发中怎么用,这里用Lua(环境使用cocos code ide)给大家说说. 先来看看项目的目录结构: 其中cocos.Co
