LinearVelocity Changing Characters Direction

[PazmaWrld (myoshakii)]

I’m trying to make a Slide System using LinearVelocity since BodyVelocity is deprecated, everything was going well until I ran into a problem. everytime near the end the players character sort of rotate to the right. I’ve tried doing everything to solve this on my own & search for similar issues but still nothing.

The script I made

-- Function
SlideAbility = function()
	
	-- Settings
	Humanoid.WalkSpeed = 0 
	Humanoid.AutoRotate = false
	
	-- Animation
	local SlideTrack = Humanoid:LoadAnimation(SlideAnimation)
	SlideTrack.Priority = Enum.AnimationPriority.Action
	SlideTrack:Play()
	
	-- Attachment Settings
	local Attachment = Instance.new("Attachment") -- Creates an attachment
	Attachment.Parent = RootPart -- Attaches the attachment to the player's root part
	Attachment.WorldPosition = RootPart.AssemblyCenterOfMass
	
	-- LinearVelocity Settings
	local Velocity = Instance.new("LinearVelocity")
	Velocity.MaxForce = 10000 -- The force of the LinearVelocity
	Velocity.Attachment0 = Attachment -- Attaches the LinearVelocity to the player's root part
	Velocity.RelativeTo = Enum.ActuatorRelativeTo.World -- Makes it so the LinearVelocity does not use person getting up as direction starting point
	Velocity.VectorVelocity = RootPart.CFrame.LookVector * SlideInfo.Speed -- The direction and speed of the LinearVelocity
	Velocity.Parent = RootPart -- Attaches the LinearVelocity to the player's root part
	
	for Count = 1,8 do -- This loop will make the player slide for a certain amount of time
		task.wait(.1) -- The amount of time the player will slide for
		Velocity.LineVelocity *= 0.7 -- The speed of the player sliding
	end
	
	

	Velocity:Destroy()
	Attachment:Destroy()
	SlideTrack:Stop()
	Humanoid.WalkSpeed = 0
	Humanoid.AutoRotate = true
end

Don’t mind the quality I’m on a potato laptop

Only fix I could think of is:

Velocity.VectorVelocity = RootPart.CFrame.LookVector * SlideInfo.Speed + Vector3.new(0, 20, 0)

It works!! Thank you! if you don’t mind can you give me a brief explanation on why this works?

In the original code when you slide, the root part is most likely colliding with the ground because of the animation. The fix I posted resolves this issue by setting the vector velocity’s y value to a high number essentially making it so that the root part may not collide with the ground.
