嘗試索引本地'v'（一個零值）

Question

我想編輯一個lua腳本來添加我的Garry的Mod服務器，但是我得到這個錯誤，我不知道該怎麼辦。

錯誤：

[ERROR] --/sh_worlditemspawner.lua:56: attempt to index local 'v' (a nil value)

代碼：

local PLUGIN = PLUGIN 
PLUGIN.name = "World Item Spawner" 
PLUGIN.author = "Black Tea" 
PLUGIN.desc = "World Item Spawner." 
PLUGIN.itempoints = PLUGIN.itempoints or {}

    ["default"] = { 
     {"bleach"}, 
    },

     {"ration"}, 
    },

Answer 1

這是因爲

table.Random(self.itempoints) 

返回nil。你的意思是math.random？如果你發佈該表的代碼。隨機func我可以給更多的信息。
