Need help forcing shiftlock | Roblox Studio Community | Page 1

This is the code im using, and it only locks the mouse in the center, and does not force shiftlock like i thought it would, and im pretty much out of ideas on how to actually make it force shift-lock, any help?

local isShiftLocked = true

local function setShiftLock(state)
    isShiftLocked = state
    
    if isShiftLocked then
        UIS.MouseBehavior = Enum.MouseBehavior.LockCenter
        UIS.MouseIconEnabled = false
    else
        UIS.MouseBehavior = Enum.MouseBehavior.Default
        UIS.MouseIconEnabled = true
    end
end

UIS.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.LeftAlt then
        setShiftLock(false)
    end
end)

UIS.InputEnded:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.LeftAlt then
        setShiftLock(true)
    end
end)

plr.CharacterAdded:Connect(function()
    task.wait(0.5)
    setShiftLock(true)
end)

setShiftLock(true)

You need to change Player camera too

#

@onyx grail

onyx grail Jul 9, 2025, 12:48 AM

#

can you elaborate?

#

(on how to do that)

#

@austere steppe

austere steppe Jul 9, 2025, 12:50 AM

#

Oh I was wrong

#

The shiftlock will lock the player in camera direction right?

#

@onyx grail

onyx grail Jul 9, 2025, 12:51 AM

#

yes

austere steppe Jul 9, 2025, 12:52 AM

#

Then change the hrp cframe with new cframe who looks in the same direction as the camera

#

Cframe.lookat(hrp.Position,workspace.currentCamera.lookVector)

#

I think

#

Did it work? @onyx grail

onyx grail Jul 9, 2025, 1:00 AM

#

austere steppe Cframe.lookat(hrp.Position,workspace.currentCamera.lookVector)

where would i put this under?

austere steppe Jul 9, 2025, 1:01 AM

#

@onyx grail

#

onyx grail Jul 9, 2025, 1:02 AM

#

#

im not sure what i would be defining Cframe as

#

wait no

#

its CFrame

austere steppe Jul 9, 2025, 1:02 AM

#

Wait

#

Show me all the code

onyx grail Jul 9, 2025, 1:02 AM

#

however, this still gets an error though

austere steppe Jul 9, 2025, 1:03 AM

#

Show the script

onyx grail Jul 9, 2025, 1:03 AM

#

austere steppe Jul 9, 2025, 1:03 AM

#

onyx grail however, this still gets an error though

I forgot a part 😭that's workspace.currentcamera.CFrame.lookVector

#

You need to do Humanoidrootpart.Cframe = Cframe.lookat(etc)

#

@onyx grail and that will work I think

onyx grail Jul 9, 2025, 1:05 AM

#

so im confused on

#

what i ened to do then

#

onyx grail Jul 9, 2025, 1:06 AM

#

austere steppe I forgot a part 😭that's workspace.currentcamera.CFrame.lookVector

onyx grail Jul 9, 2025, 1:06 AM

#

onyx grail

okay wait no im dumb

austere steppe Jul 9, 2025, 1:06 AM

#

onyx grail also changed this

No

onyx grail Jul 9, 2025, 1:07 AM

#

austere steppe No

what do i change, then?

austere steppe Jul 9, 2025, 1:07 AM

#

I'm not on pc rn so it's hard to write

#

Wait a sec

onyx grail Jul 9, 2025, 1:07 AM

#

kk

austere steppe Jul 9, 2025, 1:08 AM

#

As you already named a variable HumanoidRootPart

#

Do ```lua
Humanoidrootpart.Cframe = Cframe.lookat(Humanoidrootpart.Position, workspace.currentCamera.CFrame.lookVector

#

@onyx grail

onyx grail Jul 9, 2025, 1:10 AM

#

austere steppe Jul 9, 2025, 1:11 AM

#

@onyx grail

onyx grail Jul 9, 2025, 1:19 AM

#

local script inside StarterCharacterScripts

austere steppe Jul 9, 2025, 1:21 AM

#

Oh the problem is the lookAt function

#

Write like I did

#

lookAt

onyx grail Jul 9, 2025, 1:21 AM

#

if this is the problem

#

i hate lua

#

😭

#

yeah that was the problem

#

typical lua moment

#

it works pretty fine now

#

i appreciate it man

austere steppe Jul 9, 2025, 1:22 AM

#

Lol syntax problem are really Boring

austere steppe Jul 9, 2025, 1:22 AM

#

onyx grail i appreciate it man

Yw

#

If you have any questions you can ask

onyx grail Jul 9, 2025, 1:23 AM

#

oh god

#

the character doesnt stop falling over

#

😭

#

it worked the first time i tried it with the script and now it doesnt work anymore (i didnt change anything)

austere steppe Jul 9, 2025, 1:25 AM

#

Can you show a video

#

@onyx grail

onyx grail Jul 9, 2025, 1:27 AM

#

unfortunately no

#

basically the character just flips, spawns facing the floor

#

and then when its toggled on and off it teleports back to the floor

austere steppe Jul 9, 2025, 1:28 AM

#

Oh I got it

#

Do just before changing the Humanoidrootpart Cframe

local UnitVector = Vector3.new(workspace.currentCamera.CFrame.lookVector.X,0,workspace.currentCamera.CFrame.lookVector.Z)

#

And change the previous changer by this

Humanoidrootpart.Cframe = Cframe.lookat(Humanoidrootpart.Position, UnitVector

#

@onyx grail

onyx grail Jul 9, 2025, 1:33 AM

#

okay so now its giving me the same

#

nil error value

#

austere steppe Jul 9, 2025, 1:34 AM

#

Show the output

onyx grail Jul 9, 2025, 1:34 AM

#

wait

#

another lua moment

#

okay nope same issue

austere steppe Jul 9, 2025, 1:36 AM

#

Yeah

onyx grail Jul 9, 2025, 1:37 AM

#

hmmm

#

wait

#

another lua moment again

#

okay maybe it would be easier to

#

actually get the shiftlock script

#

and just force true it

austere steppe Jul 9, 2025, 1:41 AM

#

Nah that's not the problem

onyx grail Jul 9, 2025, 1:49 AM

#

still cargoBOT Jul 9, 2025, 1:49 AM

#

studio ** You are now Level 6! ** studio

onyx grail Jul 9, 2025, 1:49 AM

#

take a break and start this again later

when it comes to forcing stuff with the player's cursor there isn't much you can do as it's made like that for the autonomy of the user, the closest you could get using scripts to shiftlock is LockCenter mouse behavior, if your game is something that needs shift lock to be played correctly, I'm sure a player would eventually just use shift lock by themselves.
