Need bit help with rotation script

Help and Feedback Scripting Support

I got this script from one of the old devforum posts but when testing it to my own purposes it doesn’t work as I try to, I want to update the UpperTorso Y and Z or X position at all times making my character able to look at a certain part CFrame/Position passed on by a remove event but the torso just stays in 1 position all the time or shifts away from the target any tips?

--state = what state is in
--Target for this demonstration is the head

Remotes.ReadyToRotate.OnServerEvent:Connect(function(plr, state, Target)
	wait()
	local Character = plr.Character
	local WaistMotor = Character.UpperTorso.Waist
	
	while state == true do
		local NewMouseCFrame = Target.CFrame

		local NewTestCFrame=CFrame.new(WaistMotor.Transform.p,NewMouseCFrame.p)

		local Look = NewTestCFrame.LookVector

		local percentage = (Look.X/(WaistMotor.C0.X - Look.X))
		percentage = math.clamp(percentage,.1,1)

		WaistMotor.C0 = WaistMotor.C0:Lerp(CFrame.Angles(0,Look.X,0),percentage)
		Heartbeat:Wait()
	end
end)

Never change the C0.

Here’s a modernized version of that. Just change the “targetPosition” to an upvalue that gets set from your RemoteEvent

-- StarterCharacter script

local player = game.Players.LocalPlayer
local cam = workspace.CurrentCamera
local char = player.Character
local human = char:WaitForChild("Humanoid")
local rootPart = char.PrimaryPart
local upperTorso = char:WaitForChild("UpperTorso")
local waistJoint = upperTorso:WaitForChild("Waist")

-- Services
local uis = game:GetService("UserInputService")
local runService = game:GetService("RunService")
local tweenService = game:GetService("TweenService")

-- Globals
local currentSpeed = 0;
local currentTween = nil;

human.Running:Connect(function(speed)
	currentSpeed = speed
end)

local originalWaistC1 = waistJoint.C1
local maxRotation = math.rad(65)
runService:BindToRenderStep("vanityCamera", 400, function()
	local targetPosition = (cam.CFrame * CFrame.new(0,0,-1000)).p
	local torsoFront = rootPart.CFrame.LookVector
	local torsoRight = rootPart.CFrame.RightVector
	local vectorToTarget = (targetPosition - rootPart.Position)
	local rotation = math.atan2(torsoRight:Dot(vectorToTarget), torsoFront:Dot(vectorToTarget))
	
	-- Clamp the rotation
	if (rotation < -maxRotation) then
		rotation = -maxRotation
	elseif (rotation > maxRotation) then
		rotation = maxRotation
	end
	
	if (math.abs(rotation) == maxRotation and currentSpeed <= 0.5) then
		-- Rotate the bottom half to face the new direction
		local newRootPartCFrame = CFrame.new(rootPart.Position, Vector3.new(
			targetPosition.X, rootPart.Position.Y, targetPosition.Z
		))
		currentTween = tweenService:Create(rootPart, TweenInfo.new(0.33), {
			CFrame = newRootPartCFrame
		})
		currentTween:Play()
	else
		if (currentTween and currentSpeed > 0.5) then
			if (currentTween.PlaybackState == Enum.PlaybackState.Playing) then
				currentTween:Cancel()
			end
		end
		
		waistJoint.C1 = CFrame.Angles(0,rotation,0) * originalWaistC1
	end
	
end)

This is great and all but I’m not doing it so it faces my cursor, this is a sort of timed code which lasts 5 seconds where the the torso looks at the position

That’s not what my code does and I already explained how to change what it does. Are you asking me to write your code for you? The code to rotate the waist to face a targetPosition is in my code above.

It says it needs to be a StarterCharacter script, so doesnt that mean it only works from the moment you spawn? And what is upvalue
