Lua - 试图调用全局'contains'（一个零值）

Question

我很有趣，如果谁知道这段代码的问题是什么。我总是得到这个错误：

'试图调用全球“包含”（一个零值）“”

下面是代码：

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} 
state3={78} 
state4={1,2,3,4,5,6} 

playerskin=initArray2(32,0) 
wepskin=initArray2(32,0) 

function getPlayerData(id,d) 
if (d=="team") then 
    if (player(id,"team")==1) then 
     return "red" 
    end 
    if (player(id,"team")==2) then 
     return "blu" 
    end 
end 
if (d=="class") then 
    return string.lower(tf2.classes.name[tf2.classes.class[id]]) 
end 
end 

function changeSkin(id,w) 
if (contains(state1,w)) then 
    if (playerskin[id]~=0) then 
     freeimage(playerskin[id]) 
    end 
    playerskin[id]=image("gfx/tf2/skins/"..getPlayerData(id,"team").." /"..getPlayerData(id,"class").."/"..getPlayerData(id,"team").."_"..getPlayerData(id,"class").."_1.png",1,0,200+id) 
end 
if (contains(state3,w)) then

    freeimage(hat[id]) 
    hat[id]=image(crafts[tf2.classes.hatunlock[id] [tf2.classes.class[id]]].image,1,0,200+id) 
end 
end 

--[[function changeWeaponSkin(id,w)

    freeimage(wepskin[id]) 
end

end 
]] 

addhook("select","tf2.classes.images") 
function tf2.classes.images(id,w) 
if (player(id,"armor")~=206) then 
    changeSkin(id,player(id,"weapontype"))

如果你已经解决，请帮助我。

你有

if(contains(...)) then 

在你的代码段

。需要定义函数contains以便调用它。函数定义丢失。

您可以使用这样的事情（如果你想找到w表内）：

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