How to make upper body follow mouse?

Help and Feedback Scripting Support
#1

  1. What do you want to achieve? I would like to achieve making the players upper body (upper torso, arms, and head) follow their mouse while in first person.

  2. What is the issue? The problem is that right now the upper body only follows the mouse when rotating sideways. I would like to have it follow the mouse when moved up and down as well.

  3. What solutions have you tried so far? So far I have looked up tutorials on YouTube and the DevForum but was unable to find anything that helped much.

I know that many games have this system built in, so I know it must be possible, I just haven’t found any information on how to actually do it.

Please help if you can. Thank you.

Here’s how I might do it:

local lowerTorso = char.LowerTorso.Waist --//Path to the Motor6D you want to rotate
local camera = workspace.CurrentCamera

local base_CF = lowerTorso.C0 --//Cache initial CFrame for the Motor6D

local MAX_ANGLE = 45 --//Maximum rotation applied to the joint

local function lookAtCamera()
--//Compare camera's look direction to a base direction to get a scalar (or value we can use to multiply the maximum angle)

local diff = camera.CFrame.LookVector:Dot(Vector3.new(0, 1, 0))
local angle = MAX_ANGLE * diff

lowerTorso.C0 = base_CF * CFrame.Angles(0, math.rad(angle), 0)
end

game:GetService("RunService").RenderStepped:Connect(lookAtCamera)

Thanks. Will go try this out now.

Just tried this out. I am running into an error that says CFrame is not a member of the motor6D

My bad, I edited my original post.

No errors this time. It just doesn’t work - script is in startercharacterscripts - maybe that’s the problem?

Should be a LocalScript, StarterCharacterScripts should be fine.

It’s also not standalone, you might need to change like which joint to rotate as well.
