Character Lerping

Help and Feedback Scripting Support
#1

I’m trying to make it to where only above a certain walk speed, character lerping is active. Like for sprinting but not normal walking.

The issue is I can’t figure out what’s the problem with the script.

game.Players.LocalPlayer.Character.Humanoid.WalkSpeed <= 16 then

function Lerp(a, b, t)
	return a + (b - a) * t
end

local STEP = 0.1
local RunService = game:GetService("RunService")

function getYaw(vec)
	return -math.atan2(vec.Z, vec.X) - math.pi/2
end

local lastFrameDir = script.Parent.HumanoidRootPart.CFrame.lookVector
local lastDir = lastFrameDir
local dir = lastDir
local accum = 0

local rollGoal = 0
local roll = 0
RunService.Stepped:Connect(function(t, dt)
	accum = accum + dt
	lastFrameDir = dir
	dir = script.Parent.HumanoidRootPart.CFrame.lookVector

	local angleDiff = getYaw(dir) - getYaw(lastFrameDir)
	angleDiff = (angleDiff + math.pi/2) % math.pi - math.pi/2
	local sign = angleDiff < 0 and -1 or 1

	if accum > STEP then
		local diff = 1 - lastDir:Dot(dir)
		rollGoal = diff * math.rad(40) * sign

		lastDir = dir
		accum = 0
	end

	roll = Lerp(roll, rollGoal, 0.2)
	script.Parent.LowerTorso.Root.Transform = script.Parent.LowerTorso.Root.Transform * CFrame.Angles(0, 0, roll)
end)

Can anyone tell me the problem? :thinking:
