我正在尝试使用 Lua 在 Garry's Mod 上为朋友创建武器。我已经解决了所有其他错误，但我不断收到此错误：

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

我尝试在第 22 行之前放置一个函数

function SWEP.Base = "weapon_tttbase"但后来我会得到一个错误说'(' expected near =

除非 SWEP 是加载代码时已经存在的表，否则您将尝试分配给 SWEP.Base 但 SWEP 不存在（如错误所示，它为 nil）。

此外，您稍后还有多个 SWEP 函数定义。当您的代码完成运行时，只有最后一个会实际存在。该定义还将替换您最初填写的所有各种 SWEP.* 分配的任何表格。
