Keeping a part in a set position behind me

I’m not too sure what you want, but I think you want this -

So this is the script

-- put this serverScript into game.StarterPlayer.StarterCharacterScripts
local tweenService = game:GetService("TweenService")

local part = game.Workspace.Part

local character = script.Parent
local humanoidRootPart = character:WaitForChild("HumanoidRootPart")

local moveBehindTween

local prevHumanoidRootPartPos = humanoidRootPart.Position

local timeToReachDest
local easingStyle = Enum.EasingStyle.Sine
local easingDirection = Enum.EasingDirection.InOut
local noOfTimesToRepeat = 0
local reverse = false
local delayForStart = 0

while wait(0.1) do
	local humanoidRootPartPos = humanoidRootPart.Position
	local humanoidRootPartOrientation = humanoidRootPart.CFrame - humanoidRootPart.Position
	
	if humanoidRootPart == prevHumanoidRootPartPos then
		timeToReachDest = 0.5
		
		if moveBehindTween then
			moveBehindTween:Cancel()
		end
		
		local tweenInfo = TweenInfo.new(timeToReachDest, easingStyle, easingDirection, noOfTimesToRepeat, reverse, delayForStart)
		
		local targets = {
			CFrame = humanoidRootPart.CFrame + humanoidRootPartOrientation:VectorToWorldSpace(Vector3.new(-5, 0, 0))
		}
		
		moveBehindTween = tweenService:Create(part, tweenInfo, targets)
		
		moveBehindTween:Play()
		
	else	
		timeToReachDest = 0.25
		prevHumanoidRootPartPos = humanoidRootPart
		
		if moveBehindTween then
			moveBehindTween:Cancel()
		end
		
		local tweenInfo = TweenInfo.new(timeToReachDest, easingStyle, easingDirection, noOfTimesToRepeat, reverse, delayForStart)
		
		local targets = {
			CFrame = humanoidRootPart.CFrame + humanoidRootPartOrientation:VectorToWorldSpace(Vector3.new(0, 0, 5))
		}
		
		moveBehindTween = tweenService:Create(part, tweenInfo, targets)
		
		moveBehindTween:Play()
	end
	
	
end

Now it is a bit long script, but I will explain it

First of all, it uses tweening for a smooth transition. If you don’t know what tweening is, I suggest checking it out

So what this does it just every 0.1 seconds, it checks the humanoidRootPart’s position
it also has a variable called previousHumanoidRootPartPosition.
So the script just checks if the humanoids position has changed or not

If it has changed, then it sets the target CFrame to
humanoidRootPart’s Position + Vector3.new(0, 0, -5) (5 studs behind the humanoidRootPart’s Position)
So tweening comes into action and changes the position smoothly in 2.5 seconds

But if the position hasn’t changed then it just sets the target frame to
humanoidRootPart’s Position + Vector3.new(-5, 0, 0) (5 studs beside the humanoidRootPart’s Position)
And the tweening smoothly transitions it from its position to 5 studs beside the humanoidRootPart

And that’s basically it and I hope I helped.
