Question

我正在尝试添加如图所示的菜单，但这给了我错误。Error, .lua

function loadPlayerInventory()
    TBCore.Functions.TriggerServerCallback('tb-inventory:server:getPlayerInventory', function(data)
        items = 
        inventory = data.inventory
        weapons = data.weapons
        local weight = 0
        

        if inventory ~= nil then
            for k, v in pairs(inventory) do
                table.insert(items, inventory[k])
                weight = weight + (inventory[k].amount * inventory[k].weight)
            end

应该给您一个错误items =，因此您甚至不应该回叫到回调。

您忘记为项目分配值。您的代码建议它应该是一个表。

屏幕截图中的错误是由索引数据（本地nil值）引起的。

"unexpected symbol near =

这是因为调用了您的回调，但是没有给出参数inventory = data.inventory。找出原因，或者确保它不为nil。

类似

data

或

if data then
  inventory = data.inventory
end

例如

我需要帮助来修复此代码，有人可以说为什么这不起作用吗？
