Shift lock script mysteriously stops working in another place

[mister_6k (mr 6k)]

I was using LightningLion58’s force shift lock script, modified to work so it enables while a tool is equipped.

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local plr = game:GetService("Players").LocalPlayer
local char = plr.Character
local hum = char:WaitForChild("Humanoid")
local root = hum.RootPart

local Tool = script.Parent

function shiftLock(active)
	if active then		
		hum.CameraOffset = Vector3.new(1.75,0,0)
		hum.AutoRotate = false

		RunService:BindToRenderStep("ShiftLock", Enum.RenderPriority.Character.Value, function()
			UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter

			local _, y = workspace.CurrentCamera.CFrame.Rotation:ToEulerAnglesYXZ()
			root.CFrame = CFrame.new(root.Position) * CFrame.Angles(0,y,0)
		end) 
	else
		hum.CameraOffset = Vector3.new(0,0,0)
		RunService:UnbindFromRenderStep("ShiftLock")
		UserInputService.MouseBehavior = Enum.MouseBehavior.Default
		hum.AutoRotate = true
	end
end

Tool.Equipped:Connect(function()
	shiftLock(true)
end)
Tool.Unequipped:Connect(function()
	shiftLock(false)
end)

It works perfectly in the test place of my game, but when i add the tool into my main game place, it still changes the MouseBehaviour when equipping and unequipping the tool, but doesn’t do anything else.

I know it’s not interacting with any other scripts, because i tried downloading a copy of my main place and i deleted every script in starterplayer and serverscriptservice, and it was doing the exact same thing.

I’m not too experienced in scripting, but i have moderate knowledge and i seriously have no clue what could be causing this.

I tested the script you provided, and it works. Could I get some more information about it?

It works fine in newly created places, if i create a brand new place and put the tool in it works just fine, but in the main game place i’m working on, which was created 1 or 2 years ago, for some reason causes it to stop working.

When I open a large file that requires time to load, the script doesn’t function properly. Therefore, instead of using “local char = plr.Character”, I use “local char = plr.Character or plr.CharacterAdded:Wait()”. The file is created in 2018 and it is functioning when character loaded.

Nothing changed at all after adding this, the problem is exactly the same and there’s still no errors or anything appearing in output

Since there is lack of information about your game place, I can’t solve your problem .But if you want a Shift-Lock when holding weapon you can follow like this.

First, copy entire PlayerModule. Then create a Bindable event called “ShiftLock_Event”

Change the line 123 code in CameraModule where under PlayerModule

if not UserInputService.TouchEnabled then   --- line 123 
		self.activeMouseLockController = MouseLockController.new()
		local toggleEvent = self.activeMouseLockController:GetBindableToggleEvent()
		if toggleEvent then
			toggleEvent:Connect(function()
				self:OnMouseLockToggled()
			end)
		end
		local ShiftLock_Event = script.Parent.ShiftLock_Event
		if ShiftLock_Event then
			ShiftLock_Event.Event:Connect(function(input)
				self:OnMouseLockToggled(input)
			end)
		end
	end

Finding “OnMouseLockToggled” In CameraModule and change the script like this

function CameraModule:OnMouseLockToggled(input)    --- 560~570
	if self.activeMouseLockController then
	local mouseLockOffset = self.activeMouseLockController:GetMouseLockOffset()
	local mouseLocked = self.activeMouseLockController:GetIsMouseLocked()
		
	if input ~= nil then
		if self.activeCameraController then
			self.activeCameraController:SetIsMouseLocked(input)
			self.activeCameraController:SetMouseLockOffset(mouseLockOffset)
		end
	else
	
		if self.activeCameraController then
			self.activeCameraController:SetIsMouseLocked(mouseLocked)
			self.activeCameraController:SetMouseLockOffset(mouseLockOffset)
		end
	end	
	end
end

Create Local Script under tool and copy this script

local Tool = script.Parent
local PlayerMoudle = game.Players.LocalPlayer.PlayerScripts.PlayerModule
local CameraModule =require(PlayerMoudle.CameraModule)
local MouseLockController = require(PlayerMoudle.CameraModule.MouseLockController)
ShiftLock_Event = PlayerMoudle.ShiftLock_Event

function shiftLock(Active)
	ShiftLock_Event:Fire(Active)
	
end

Tool.Equipped:Connect(function()
	shiftLock(true)
end)
Tool.Unequipped:Connect(function()
	shiftLock(false)
end)

And this also works when “EnableMouseLockOption” is disabled
