Unexpected camera rotation changes | Roblox Studio Community | Page 1

hello i need help with my 51 lines of camera system, so when i toggle the Alternative move (by pressing F for the first time) it do change the Position but also the "Rotation" causing disproportion between default and alternative mode. You can test the script below:

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

local player = Players.LocalPlayer
local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera.FieldOfView = 55

-- Settings
local default_offset = Vector3.new(0, 20, -20)
local alternative_offset = Vector3.new(0, 20, 0)
local offset = default_offset

local function onCharacterAdded(character)
local root = character:WaitForChild("HumanoidRootPart")
local renderConnection

renderConnection = RunService.RenderStepped:Connect(function()
    if not root or not root.Parent then
        renderConnection:Disconnect()
        return end
    
    local cameraPos = root.Position + offset
    camera.CFrame = CFrame.lookAt(cameraPos, root.Position)
end)

character.AncestryChanged:Connect(function(_, parent)
    if not parent then
        if renderConnection then
            renderConnection:Disconnect()
            renderConnection = nil
        end
    end
end)

end

local Alternative_mode = false
UserInputService.InputBegan:Connect(function(input, gameProcessed)
if gameProcessed then return end
if input.KeyCode == Enum.KeyCode.F then
Alternative_mode = not Alternative_mode
if Alternative_mode then
offset = alternative_offset
else
offset = default_offset
end
end
end)

player.CharacterAdded:Connect(onCharacterAdded)

hold on just putting it on format

nice, what did you do?

balmy hatch bro just removed some words 💀

dawgh

#

i just said im putting it in format

#

for me to read it

#

😭

#

💔

balmy hatch Oct 12, 2025, 8:23 AM

#

oh

#

i though you copied it and tested in studio

#

sorry man

balmy hatch Oct 12, 2025, 8:24 AM

uneven vessel 💔

sorry man

uneven vessel Oct 12, 2025, 8:25 AM

balmy hatch sorry man

wheres the first argument?

#

and/or what is the first argument?

balmy hatch Oct 12, 2025, 8:26 AM

#

oh what i literarry copied the whole code by CTRL + A

uneven vessel Oct 12, 2025, 8:26 AM

#

also i think you forgot to add the underscore in the offset, or is this just a snippet?

this is the ful code

#

should be 51 lines

uneven vessel Oct 12, 2025, 8:27 AM

#

oh nvm im the one whos tripping

#

there was two underscores that turned it into

#

this type of text

balmy hatch Oct 12, 2025, 8:27 AM

#

uneven vessel oh nvm im the one whos tripping

nah i'ts okay

#

wait i think i can't copy the "_" from the script. You know whats wrong right?

uneven vessel Oct 12, 2025, 8:30 AM

#

is this whats supposed to happen?

balmy hatch Oct 12, 2025, 8:30 AM

#

uneven vessel is this whats supposed to happen?

yes like that

#

but when you toggle the alt mode, you will notice that the camera will be rotated

@balmy hatch

#

hiya!

#

The issue was because of the LookVector

#

^^

balmy hatch Oct 12, 2025, 8:53 AM

#

wow thanks @uneven vessel i will test it out!

#

@uneven vessel I appreciate your help but unfortunatly, that's not what i want :c. If you wish to help me once again, i think you may need this video to understand what i want to do https://youtu.be/huPpm6ZIgeo?si=NYuZhzZiloIR-HDg

you might notice that at the 14th second, he toggled the second camera mode and thats what i want

uneven vessel Oct 12, 2025, 9:08 AM

#

i see

#

so its just slightly rotated?

balmy hatch Oct 12, 2025, 9:18 AM

#

uneven vessel so its just slightly rotated?

Idk how to answer but it should be like in the video (sorry for the late reply)

#

In my case when I toggle the alternative mode. It seems like the camera rotated counterclockwise 90 degrees based on the default mode

the issue was actually.. quite simple...

#

to fix

#

..

#

💔

#

and i overcomplicated it

balmy hatch Oct 12, 2025, 9:29 AM

#

WHAT DID YOU DO!?!?

uneven vessel Oct 12, 2025, 9:29 AM

#

balmy hatch WHAT DID YOU DO!?!?

made lookCframe as a variable so i can add the CFrame.Angles as a optional option for you

#

but overall

#

i just changed
alternative_offset = Vector3.new(0, 20,0)
to

#

alternative_offset = Vector3.new(0, 20, -6)

balmy hatch Oct 12, 2025, 9:30 AM

#

Okay, I'll test it out!

uneven vessel Oct 12, 2025, 9:32 AM

#

Hope this fixes your issue! ^^

balmy hatch Oct 12, 2025, 9:32 AM

#

uneven vessel Hope this fixes your issue! ^^

YES BRo It Worked!!!!

uneven vessel Oct 12, 2025, 9:33 AM

#

Also just to explain,

When you set it to
Vector3.new(0, 20, 0)
your camera was positioned directly above the character, same X and Z as the target.
That makes the direction vector from camera -> root

#

(root.Position - (root.Position + Vector3.new(0, 20, 0))) = Vector3.new(0, -20, 0)
That’s perfectly vertical.

#

CFrame.lookAt() can’t build a stable rotational frame from a direction like (0, -1, 0) because there’s no clear “right” or “forward” direction.

#

by just introducing (0, 20, -1) it changes it, making it not perfectly horizontal

#

or even (0, 20 -0.01) wont make it perfectly horizontal

balmy hatch Oct 12, 2025, 9:36 AM

#

Okay. Thanks for the help and the explaination mate! @uneven vessel

uneven vessel Oct 12, 2025, 9:37 AM

No problem!
