所有 ModuleScript 变量 == nil

Question

由于某种原因，我的模块脚本中的局部变量似乎都是nil，没有确切的解释或解决方案。 本地脚本（耐力条脚本）：

local ms = require(game.ReplicatedStorage.ModuleScript)
if not ms then
    
    local ms = require(game.ReplicatedStorage:WaitForChild("ModuleScript"))
    
end

local TW = game:GetService("TweenService")--Get Tween Service

local Staminabar = script.Parent -- Get The Stamina bar

local function UpdateStaminabar() --Stamina Bar Size Change Function
    local stamina = math.clamp(ms.stamina / ms.maxstamina, 0, 1) --Maths
    local info = TweenInfo.new(ms.stamina / ms.maxstamina,Enum.EasingStyle.Linear,Enum.EasingDirection.InOut,0,false,0) --Tween Info
    TW:Create(script.Parent,info,{Size = UDim2.fromScale(ms.stamina, 1)}):Play() -- Create The Tween Then Play It
end

UpdateStaminabar()--Update The Health Bar

ms.stamina:GetPropertyChangedSignal("Value"):Connect(UpdateStaminabar) --Update The Health Bar When The Health Change
ms.maxstamina:GetPropertyChangedSignal("Value"):Connect(UpdateStaminabar) --Update The Health Bar Wheb The MaxHealth Change

LocalScript（战斗脚本）：

local ms = require(game.ReplicatedStorage.ModuleScript)
if not ms then
    
    local ms = require(game.ReplicatedStorage:WaitForChild("ModuleScript"))
    
end 
local uis = game:GetService("UserInputService")
local cas = game:GetService("ContextActionService")
local rs = game:GetService("ReplicatedStorage")

local events = rs:WaitForChild("Events")
local hitbox = events:WaitForChild("Hitbox")

local plr = game.Players.LocalPlayer
local character = plr.Character
if not character then
    
    plr:WaitForChild("Character")
    
end
local humanoid = character.Humanoid
local animator = humanoid:WaitForChild("Animator")

local idle = animator:LoadAnimation(script:WaitForChild("idle"))
local jab = animator:LoadAnimation(script:WaitForChild("jab"))
local rightcross = animator:LoadAnimation(script:WaitForChild("rightstraight"))
local lefthook = animator:LoadAnimation(script:WaitForChild("lefthook"))
local righthook = animator:LoadAnimation(script:WaitForChild("righthook"))
local swingsfx = script:WaitForChild("Air swing")

local currentPunch = 0
local currentPunch2 = 0
local debounce1 = false
local debounce2 = false

local function onInputBegan(input)
    
    if debounce2 == true then return end
    if ms.stamina <= 0 then return end
    
    
    if input.KeyCode == Enum.KeyCode.Q then
        
        ms.stamina -= 20
        debounce2 = true
        humanoid.WalkSpeed = 0.5
        lefthook:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(4.5, 1), 7.5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        lefthook:Stop()
        task.wait(6)
        debounce2 = false
        
    end 
    
    if input.KeyCode == Enum.KeyCode.E then

        ms.stamina -= 20
        debounce2 = true
        humanoid.WalkSpeed = 0.5
        righthook:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(4.5, 1), 7.5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        righthook:Stop()
        task.wait(6)
        debounce2 = false

    end 
end

local function punch()
    
    if debounce1 then return end
    
    debounce1 = true
    if currentPunch == 0 then
        
        ms.stamina -= 10
        humanoid.WalkSpeed = 0.6
        jab:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(5.7, 1), 2.5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        jab:Stop()
        debounce1 = false
        
    elseif currentPunch == 1 then
        
        ms.stamina -= 10
        humanoid.WalkSpeed = 0.6
        rightcross:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(5.7, 1), 2.5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        rightcross:Stop()
        debounce1 = false
        
    elseif currentPunch == 2 then
        
        ms.stamina -= 10
        humanoid.WalkSpeed = 0.6
        jab:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(5.7, 1), 2.5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        jab:Stop()
        debounce1 = false
        
    elseif currentPunch == 3 then
        
        ms.stamina -= 10
        debounce2 = true
        humanoid.WalkSpeed = 0.6
        rightcross:Play()
        swingsfx:Play()
        hitbox:FireServer(Vector3.new(4, 5, 3), Vector3.new(5.7, 1), 5, 0.15)
        task.wait(0.5)
        humanoid.WalkSpeed = 10
        rightcross:Stop()
        debounce1 = false
        debounce2 = false
        
    end

    if currentPunch == 3  then
        
        currentPunch = 0
        debounce1 = true
        wait(2)
        debounce1 = false
        
    else
        
        currentPunch += 1
        
    end
    
end

cas:BindAction("Punch", punch, true, Enum.UserInputType.MouseButton1)
uis.InputBegan:Connect(onInputBegan)

模块脚本：

local info = {}

    local stamina = 100
    local maxstamina = 100
    
return info

我试图制作一个耐力系统，以及一个耐力条，但他们只是拒绝使用当地人，而是打印出如下错误：

15:00:30.915 Players.Morelval1.PlayerGui.ScreenGui.StaminaBar.Frame.StaminaBar 脚本：12：尝试对 nil 执行算术（div） - 客户端 - StaminaBar 脚本：12 15:00:32.505 Players.Morelval1.PlayerGui.Main.PunchScript:39：尝试比较 nil <= number - Client - PunchScript:39

我期待变量能够交互并被使用。

Answer 1

local ms = require(game.ReplicatedStorage.ModuleScript)
if not ms then
    
    local ms = require(game.ReplicatedStorage:WaitForChild("ModuleScript"))    
end

第二个

ms

是 if 语句的局部变量。它遮盖了第一个

ms

。因此，如果第一个 require 失败，您会将第二个 require 的返回值存储到错误的变量中。

删除 local 关键字。

local ms = require(game.ReplicatedStorage.ModuleScript)
if not ms then
    
    ms = require(game.ReplicatedStorage:WaitForChild("ModuleScript"))    
end

或者简单地

local ms = require(game.ReplicatedStorage.ModuleScript)
         or require(game.ReplicatedStorage:WaitForChild("ModuleScript"))    

当然，在继续之前，您仍然应该检查第二次 require 尝试是否成功。
