Lua-尝试调用全局“包含"(nil值) [英] Lua - attempt to call global 'contains' (a nil value)

问题描述

我很有趣，如果谁知道下面的代码是什么问题.我总是会收到此错误:

I'm interesting, if who know what is the problem of this code bellow. I always get this error:

``试图调用全局'contains'(nil值)''

''attempt to call global 'contains' (a nil value)''

这是代码:

state1={10,11,20,21,22,23,24,30,31,32,33,34,35,36,37,38,39,40,45,46,47,48,49,50,51,69,72,73,74,85}

推荐答案

您拥有的

if( contains(...) ) then

在您的代码段中.需要定义函数 contains 才能被调用.函数定义丢失.

in your code segments. The function contains need to be defined for it to be called. The function definition is missing.

您可以使用类似这样的东西(如果您想在表中找到 w ):

You can use something like this(if you want to find w inside the table):

function contains( tPassed, iValue )
    for _, v in pairs( tPassed ) do
        if tonumber(v) == tonumber(iValue) then
            return true
        end
    end
    return nil
end
