Lua_基本Lua语法

Lua_面向对象
-- 在Lua中不能定义类，但可以使用table类型变量来当成对象，对象有成员变量和成员方法，例如下面的例子：Student = {id = 100, name = "Tony"}function Student:toString() local s = "Name:" .. Student.name .. " id:" .. Student.id return sendprin原创 2015-04-15 23:53:42 · 472 阅读 · 0 评论 -

Lua_table中常用的四种遍历方式
--第一种遍历方式：--[[for key, value in ipairs(table) do end注：这种方式的遍历只会从key为1的地方开始，一直以key递增1的顺序来遍历，若找到一个递增不是1的key就结束遍历，无论后面是否仍然是顺序的key。请看下面例子：]]--Sample_1:local tab1 = { [1] = 1, [2] = 2, [3] =原创 2015-04-07 13:21:35 · 18760 阅读 · 0 评论 -

Lua_多重排序
网上有好多排序，不过写的都大同小异。本文讲解下多重排序，意思是多个条件排序。 前提： 1.Lua排序的原理是冒泡排序,即从前往后比较,满足一定条件A则交换,否则不交换。 2.Lua排序函数table.sort(tbl, sortFunc), sortFunc中会比较前后表中前后两个值,sortFunc函数返回true则不交换,返回false则交换。 例子：table_demo原创 2015-05-02 19:21:54 · 1317 阅读 · 0 评论 -

Lua_Lua中的闭包小结
前言在很多语言中都有闭包的概念，而在这里，我将主要对Lua语言的闭包概念进行分析与总结。希望对大家学习Lua有帮助。什么是闭包？闭包在Lua中是一个非常重要的概念，闭包是由函数和与其相关的引用环境组合而成的实体。我们再来看一段代码：复制代码 代码如下:function newCounter() local i = 0 return functio原创 2015-11-07 17:09:19 · 733 阅读 · 0 评论
