Goofy ah character flickering during sliding

sup everyone so for some unknown reason my character like flickers around during a sliding animation. im using alignorientation with a code snippet below. if anybody knows what the heck is going on that would be very helpful thanks gurt

alignOrientation = Instance.new(“AlignOrientation”)
alignOrientation.MaxTorque = 40000
alignOrientation.Responsiveness = 10000
alignOrientation.Attachment0 = rootPart:FindFirstChildOfClass(“Attachment”)
alignOrientation.Mode = Enum.OrientationAlignmentMode.OneAttachment
alignOrientation.Parent = Character

PosCheck = RunService.RenderStepped:Connect(function(dt)
	local currentY = rootPart.Position.Y
	local verticalChange = currentY - previousY
	previousY = currentY
	
	-- Determine slope behavior
	if verticalChange > 0.01 then
		-- Going uphill
		CurrentMultiplier = math.clamp(CurrentMultiplier - Settings.SpeedChangeRate.Upward * dt, 0, Settings.MaxMultiplier)
	elseif verticalChange < -0.01 then
		-- Going downhill
		CurrentMultiplier = math.clamp(CurrentMultiplier + Settings.SpeedChangeRate.Downward * dt, 0, Settings.MaxMultiplier)
	else
		-- Flat
		CurrentMultiplier = math.clamp(CurrentMultiplier - Settings.SpeedChangeRate.Flat * dt, 0, Settings.MaxMultiplier)
	end

	-- Apply movement
	local horizontalMove = Vector3.new(Humanoid.MoveDirection.X, 0, Humanoid.MoveDirection.Z)

	-- Only slightly influence the slide direction
	local influence = 0.1  -- small = slide mostly goes forward
	if horizontalMove.Magnitude > 0 then
		local targetDir = (slideDir + horizontalMove.Unit * influence).Unit
		slideDir = slideDir:Lerp(targetDir, 0.1).Unit
	end
	
	-- Then apply horizontal velocity
	local horizontalVel = slideDir * (Settings.BaseSpeed * CurrentMultiplier)

	-- Smooth velocity lerp for less jerky movement
	local currentVel = Vector3.new(rootPart.AssemblyLinearVelocity.X, 0, rootPart.AssemblyLinearVelocity.Z)
	horizontalVel = currentVel:Lerp(horizontalVel, 0.2) -- smooth factor 0.2
	rootPart.AssemblyLinearVelocity = horizontalVel + Vector3.new(0, rootPart.AssemblyLinearVelocity.Y, 0)
	
	local rayDir = rootPart.CFrame.UpVector * -10
	local groundRay = workspace:Raycast(rootPart.Position,rayDir,rayParams)

	if groundRay then
		local up = groundRay.Normal

		-- Forward direction is the original slideDir (horizontal)
		local forward = Vector3.new(slideDir.X, 0, slideDir.Z).Unit

		-- Right vector perpendicular to up and forward
		local right = forward:Cross(up).Unit

		-- Compute lean: rotate a bit toward horizontalMove
		local leanAmount = 0.2  -- 0 = no lean, 1 = full sideways
		if horizontalMove.Magnitude > 0 then
			local leanDir = Vector3.new(horizontalMove.X, 0, horizontalMove.Z).Unit
			forward = (forward:Lerp(leanDir, leanAmount)).Unit
			right = forward:Cross(up).Unit
		end

		-- Final orientation
		local backForward = right:Cross(up).Unit
		-- Compute target orientation as before
		local targetCFrame = CFrame.fromMatrix(rootPart.Position, right, up, backForward)

		-- Smoothly interpolate from previous orientation
		alignOrientation.CFrame = alignOrientation.CFrame:Lerp(targetCFrame, 0.2) -- tweak 0.1-0.3
	end

js put it into a lua code chunk so its easier to read - ill give it some thought

also the chat gpt is so obvious :rofl: nothing wrong in using it tho

fr bro haha for this system though it’s been incredibly buns

Setting a parts AssemblyLinearVelocity directly is probably interfering with your AlignOrientation. Use something like a VectorForce or a LinearVelocity instead. Also at the end, you don’t need to lerp the AlignOrientation because that’s already handled on the Responsiveness property (sortof but you get literally the same effect). Also, did you disable AutoRotate on the humanoid? And is PlatformStand enabled?

totally my bad guys it was a freaking problem with my fp camera script :skull: stupid me shouldn’t trust nonna the shart on the toolbox but thanks for offering y’all’s help
