How to Force Enable Shift-Lock (Without changing the PlayerModule)

[EvidenceCross (Evidence)]

I presume this is used when making camera over the shoulder gun systems.

[sausagerate (theo)]

how can i disconnect the lock or shiftlock like when the intermission is the the shiftlock is disconnect or disable or i unequipped tool

[LightningLion58]

shiftLock(false)

If you have a script from the server, you can use remote events to toggle off shift lock for everyone.

i changed the script to this and the mouse is broken, when I disable it, it wont release the mouse

local plr = game:GetService("Players").LocalPlayer
local mouse = plr:GetMouse()
local char = script.Parent
local hum = char:WaitForChild("Humanoid")
local rotation = Instance.new("BodyGyro") 
local Root = plr.Character.HumanoidRootPart
rotation.P = 1000000 
rotation.Parent = hum.RootPart 
local conn 

function shiftLock(value,active) 
	if active then
		hum.CameraOffset = Vector3.new(value,0.5,0) 
		rotation.MaxTorque = Vector3.new(0, math.huge, 0) 
		conn = game:GetService("RunService").RenderStepped:Connect(function()
			rotation.CFrame = mouse.Origin
			game:GetService("UserInputService").MouseBehavior = Enum.MouseBehavior.LockCenter
		end) 
	else
		hum.CameraOffset = Vector3.new(0,0,0) 
		rotation.MaxTorque = Vector3.new(0, 0, 0) 
		if conn then conn:Disconnect() end 
	end
end

game.ReplicatedStorage.Shiftlock.OnClientEvent:Connect(shiftLock)

i fixed it myself the script is very helpfull ty

[NarutoandGokuUi101 (Cross)]

I’ve an odd problem, where I’ve set the character to R6, but after I implemented this script, and tested it, it’s now an R15 character. What’s going on?

[LightningLion58]

This script does not change any character parts.

Did you change the character from the Avatar editor? Or game settings?

If from avatar editor, try from the game settings.

Game Settings → Avatar → Avatar Type → R6

[RocketB0ii (Rocket)]

Man, your code format…

But hey, no offense, I can fix that

Nice anyway!

My mouse got locked on the center sometimes, any reason?

[LightningLion58]

Yes, but you can disable it

@The_Saver31

game:GetService("UserInputService").MouseBehavior

Like the original shiftlock, the mouse is locked in the center. So the mouse locking is on purpose, but you can easily disable it.

The shift lock icon

If you want your character to face the mouse/camera without the centering, you can just remove all of these MouseBehavior lines.

[batteryday]

Hi stupid question but I can’t seem to figure it out,

How would I move the character by setting HumanoidRootPart CFrame directly?

I tried this but it makes the character completely glitch out:

rootPart.CFrame = CFrame.new(rootPart.CFrame.Position) * camera.CFrame.Rotation

I also tried taking out the X axis from the rotation but then it didn’t rotate at all

[venoct10]

Thanks! I found this very helpful when making a horror game. Its very dark(as intended) but I needed the flashlight to stay in one spot so when people joined the game they could see. Very Helpful

[SaturdayScandal (scan)]

Can confirm that the actual camera offset for shiftlock is 1.75, 0, 0 after looking through the scripts. Great system! But, now that bodygyro is deprecated, wouldn’t you need some replacements? I tried using align orientation but its jittery

[LightningLion58]

Hey .
As far as I know, BodyGyro is legacy, not deprecated. It still remains and is unlikely to be removed, though not further developed and not fully supported as well.

There's no indication that legacy BodyMovers are deprecated

I have some information on this when I was writing the BodyMover pages. I did ask about this and the response that I got was that BodyMovers are legacy, not deprecated. The difference is the intention on their removal - BodyMovers are so widely used they aren’t going anywhere anytime soon. Neither legacy nor deprecated things will be updated, but deprecated could be removed at any time. See also the legacy font for text UI objects. In other words, it’s better practice if you use more modern alt…

They are not going anywhere.
In this case, I find BodyGyro much simpler and straightforward to use.

---

Though theoretically, you're right about that the alternative should be used instead.

I might provide some further alternative methods to achieve this (Align orientation or CFraming). I planned to update this thread for a while now, but I’ve had no time.

[LightningLion58]

Hello, sorry for the late reply.

I’ll provide this alternative soon.

[SaturdayScandal (scan)]

https://developer.roblox.com/en-us/api-reference/class/BodyGyro

Says here it’s indeed deprecated and is no longer legacy.

[Ozzypig]

Hiya, you linked my post which was 3 years out of date - I updated it just now, but figure I echo things here: BodyMovers and their subclasses were deprecated in update 516 (March 1st, 2022). Like all deprecated stuff, they shouldn’t be used for new work, and as far as I know there’s no guarantee they’ll continue to work the way they do today, or at all.

The word legacy is a sort of softer classification of API members (and somewhat unofficial), as it doesn’t have a corresponding API dump tag. Stuff that you probably want to avoid due to age but isn’t yet depreciated is probably safe to consider legacy.

[LightningLion58]

Hello @batteryday , @SaturdayScandal and @Ozzypig .

Thank you for notifying me that BodyGyro has been deprecated.

I’ve come up with a solution based on CFrame.

I'll update the thread very soon, but for now, here's the alternative for you to use:

--Local script in StarterPlayerCharacter
--Variables:
local plr = game:GetService("Players").LocalPlayer
local char = script.Parent
local hum = char:WaitForChild("Humanoid")
local root = hum.RootPart -- The HumanoidRootPart


--Toggle Function:
function shiftLock(active) --Toggle shift.lock function
	if active then
		hum.AutoRotate = false --Disable the automatic rotation since we set it.
		hum.CameraOffset = Vector3.new(1,0.5,0) -- I assume this is about the right camera offset.
		game:GetService("RunService"):BindToRenderStep("ShiftLock", Enum.RenderPriority.Character.Value, function()
			local _, y = workspace.CurrentCamera.CFrame.Rotation:ToEulerAnglesYXZ() --Get the angles of the camera
			root.CFrame = CFrame.new(root.Position) * CFrame.Angles(0,y,0) --Set the root part to the camera's rotation
			game:GetService("UserInputService").MouseBehavior = Enum.MouseBehavior.LockCenter
		end) --Set the mouse to center every frame.
	else
		hum.CameraOffset = Vector3.new(0,0,0) --Move the camera back to normal.
		game:GetService("RunService"):UnbindFromRenderStep("ShiftLock") -- Allow mouse to move freely.
		hum.AutoRotate = true
	end
end
--Disable and Enable:
shiftLock(true) -- Toggle shift lock
print("Shift lock turned on!")

task.wait(15)
shiftLock(false) -- Toggle shift lock

Edit: The thread is now updated.

[xdeno]

Hey, thanks for this script! However two things, the correct lock shift offset is Vector3.new(1.75,0,0) and you forget to set the MouseBehavior back to default. Other than that perfect! Thank you for the script

game:GetService("UserInputService").MouseBehavior = Enum.MouseBehavior.Default

--Toggle Function:
function shiftLock(active) --Toggle shift.lock function
	if active then
		hum.AutoRotate = false --Disable the automatic rotation since we set it.
		hum.CameraOffset = Vector3.new(1.75,0,0) -- I assume this is about the right camera offset.
		game:GetService("RunService"):BindToRenderStep("ShiftLock", Enum.RenderPriority.Character.Value, function()
			local _, y = workspace.CurrentCamera.CFrame.Rotation:ToEulerAnglesYXZ() --Get the angles of the camera
			root.CFrame = CFrame.new(root.Position) * CFrame.Angles(0,y,0) --Set the root part to the camera's rotation
			game:GetService("UserInputService").MouseBehavior = Enum.MouseBehavior.LockCenter
		end) --Set the mouse to center every frame.
	else
		hum.CameraOffset = Vector3.new(0,0,0) --Move the camera back to normal.
		game:GetService("RunService"):UnbindFromRenderStep("ShiftLock") -- Allow mouse to move freely.
		hum.AutoRotate = true
        game:GetService("UserInputService").MouseBehavior = Enum.MouseBehavior.Default
	end
end

[LightningLion58]

Hey, thank you for the accurate offset! I used an estimate since I did not know exactly what the real one was.

@xdeno

you forget to set the MouseBehavior back to default

Actually, the MouseBehavior is constantly set to default, which is why I used RenderStepped .

Therefore when disconnecting the RenderStepped, the behavior will be set back, therefore there’s no need to do that manually.

Turns out you’re right. It used to be constantly set but now you have to set it back.

I updated it, thanks !
