Lerping with overshooting

[CodyTheDwagon (cody)]

I’m working on project right now and I want to have a part locked to the camera’s position, but have the rotation smoothed. I know how to use lerping to get this effect, but the issue comes in when I want it to sort of overshoot the goal similar to the “Back” EasingStyle. Any help with this is appreciated, thanks :>

Could try TweenService:GetValue()?

How would I go about applying it to a function that updates on RenderStepped?

After looking for a bit, I found this module that works really well for what I’m trying to do.

Try mess around with this code:

local start = 0 --start
local goal = 5 --goal
local tweenInfo = TweenInfo.new(2, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut)

local value = 0
local elapsed = 0
local cnStepped

local function onStepped(t, dt)
	elapsed = math.min(elapsed + dt, tweenInfo.Time)
	
	local alpha = game:GetService('TweenService'):GetValue(elapsed / tweenInfo.Time, tweenInfo.EasingStyle, tweenInfo.EasingDirection)
	
	value = start + (goal - start) * alpha --you might recongize this: it's the equation for a lerp
	
	print(value)
	
	if elapsed >= tweenInfo.Time then
		cnStepped:Disconnect()
	end
end

onStepped = game:GetService('RunService').Stepped:Connect(onStepped)
