Question

我需要帮助解决一个非常烦人的错误，我已经使用我的GMOD游戏模式。我正在尝试制作自定义菜单，但我收到此错误：

[ERROR] gamemodes/tdm/gamemode/custom_menu.lua:20: attempt to call global 'addButtons' (a nil value)
  1. gameMenu - gamemodes/tdm/gamemode/custom_menu.lua:20
   2. unknown - gamemodes/tdm/gamemode/custom_menu.lua:32
    3. include - [C]:-1
     4. unknown - gamemodes/tdm/gamemode/cl_init.lua:3

这是我的代码：

custom_menu.lua

local Menu

function gameMenu()
    if(Menu == nil) then
        Menu = vgui.Create("DFrame")
        Menu:SetSize(750, 500)

Answer 1

你打电话

concommand.Add("open_game_menu", gameMenu())

此时调用addButtons(Menu) nil，因为函数定义在concommand.Add("open_game_menu", gameMenu())之后。{/ p>

一切都在那里。您只需阅读错误消息。

更改脚本中的顺序以修复错误。

试图调用全局＆＃39; addButtons＆＃39; （零值）
