你好，这是我在这里的第一篇文章，所以我想打个招呼。所以，作为一个初级程序员，我正在尝试为我的 mta 服务器实现一个关卡系统，但是，我遇到了标题中所述的障碍。这个布尔值在哪里？我怎样才能让它工作？如果这个问题看起来微不足道（确实如此），我很抱歉，但我真的很想继续前进。任何帮助将不胜感激提前谢谢！

错误在 setElementData(player, table[i], getElementData(player, table[i]) + 1); 我能做些什么来使它工作任何帮助将不胜感激

错误行 70 尝试对布尔值执行算术并警告同一行

错误参数@ getElementData [参数 1 中的预期元素，得到 nil ]

首先，请不要table用作变量名。我还没有为 Multi Theft Auto 写过文章，但我猜它有 Lua 内置表库，你会覆盖它。

如果该元素的数据不存在，getElementData 将返回 false，因此您需要检查以确保它存在。

您的代码正在做的是，在每个玩家生成时将该项目的数量增加一个，我假设您真正想要做的只是给玩家一个该项目？

不管怎样，是这样的：

 addEventHandler("onPlayerSpawn", root, function(lvl)
        if not lvl then lvl = getElementData(player, "lvl") or 0; end
        if lvl >= 1 then
            for i = 1, lvl do
                local itemCount = getElementData(player, table[i]) or 0
                setElementData(player, table[i], itemCount + 1);
            end
        end
    end);

如果您只是想在每个生成点上添加一个项目而不是将其增加 1，那么请执行此操作 setElementData(player, table[i], 1);

getElementData如果您要求的元素不存在，则可以返回 false。我假设您希望将其视为 0，因此请替换getElementData(player, table[i]) + 1为(getElementData(player, table[i]) or 0) + 1.

此外，看起来你player那里没有变量，所以它使用 nil 全局变量，所以你总是会得到 nil。要解决这个问题，请local player = source在处理程序的开头执行onPlayerSpawn。

所以我使用你的函数，我的代码看起来像这样

   table = {"Milk","MP5A5","M4A1-S","AK-47","Soda Bottle","Pizza","AS50","Tent","Medium Tent","ACR","AR-15","M107","Pasta Can","Beans Can","Golf Club"} 

addEventHandler("onPlayerSpawn", root, function(lvl)
local player = source 
    if not lvl then lvl = getElementData(player, "lvl") or 0; end
    if lvl >= 1 then
        for i = 1, lvl do
            setElementData(player, "lvl", table[i], (getElementData(player,"lvl", table[i]) or 0) + 1);
        end
    end
end);

我添加了“lvl”bcs prnt.sc/sc9hk1 我得到但仍然无法工作，现在我有这个错误：https ://prnt.sc/scajbc
