【进阶实战】Lua pcall探测：仓库整理脚本的容错封装

local function sortStorage(actor)
    local list = getsysvar("Store_" .. getplayvar(actor, "ACC"))
    table.sort(list)               -- 键缺失时 list 为 nil，当场炸
end

local function sortStorageSafe(actor)
    local ok = pcall(function()
        local key = "Store_" .. getplayvar(actor, "ACC")
        local list = getsysvar(key)
        if list == "" then return end
        local t = {}
        for id in string.gmatch(list, "%d+") do
            table.insert(t, tonumber(id))
        end
        table.sort(t)
        setsysvarex(key, table.concat(t, ","), 1)
    end)
    if not ok then
        sendmsg(actor, 1, "整理失败，已保留原样")
    end
end
