lua支持的类型有以下几种:nil、boolean、 number、string、userdata、function、thread 和 table。使用type函数可以用来测试变量的类型,如: t = 10 print(type(t)) -- number t = "hello world" print(type(t)) -- string t = type print(type(t)) -- function t = nil print(type(t)) -- nil t...

此外,和__index一样,Lua也同样提供了避开元方法而直接操作当前table的函数rawset(table,key,value),其功能类似于rawget(table,key)。 3). 具有默认值的table:缺省情况下,table的字段默认值为nil。但是我们可以通过元表修改这个默认值,如: function setDefault(table,default) local mt = {__index = function() ...
-- gMyTable["name"] = "lucy" -- gMyTable["age"] = 18 -- gMyTable["sex"] = "woman" -- gMyTable[1] = "测试" --> 遍历表 -- for k,v in ipairs(gMyTable) do -- print(k,v) -- end --> 直接访问表内元素 -- print(gMyTable[1]) -- print(gMyTable["name"]) -- for ...

function Shape:printArea() print("面积为 ",self.area) end 然后我们可以实现另一个table,来表示另一个类,设置这个新的类的元表为旧类的元表,我们就继承了旧类的函数。比如: Square = Shape:new() -- 派生类方法 new function Square:new(o,side) ...
