嘗試將全局“ SWEP”修復為零

Question

我正在嘗試為Gara's Mod與Lua上的朋友創建武器。 我已經通過所有其他錯誤，但我一直收到此錯誤：

input:22: attempt to index global SWEP (a nil value)

我嘗試將一個函數放在第22行之前

function SWEP.Base = "weapon_tttbase"但隨后我會收到一條錯誤消息，說'(' expected near =

Answer 1

除非SWEP是在加載代碼時已經存在的表，否則您嘗試分配給SWEP.Base但SWEP不存在（錯誤指示為nil）。

另外，稍后您將對SWEP函數有多個定義。 當您的代碼完成運行時，只有最后一個實際上將存在。 該定義還將替換您最初用所有各種SWEP。*分配填充的任何表。
