AlignPosition moving the player slighly up

[MrSlimer123 (bog)]

I’m currently trying to use AlignPosition for dashing, as it seems the most reliable, in terms of distance.
There’s a slight problem though, and that’s when i dash, it moves the character slightly up, which can cause some unwanted behaviour.

This is the function itself:

function MovementController:Dash()

	local playerCharacter = self.Owner.Character
	local rootPart = playerCharacter:FindFirstChild("HumanoidRootPart")
	local humanoid = playerCharacter:FindFirstChild("Humanoid")
	local dashDirection = humanoid.MoveDirection
	local maxDashDistance = self.DashingDistance

	if humanoid.MoveDirection.Magnitude < 0.1 then
		dashDirection = rootPart.CFrame.LookVector
	end

	dashDirection = Vector3.new(dashDirection.X, 0, dashDirection.Z).Unit

	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {workspace.Map}
	raycastParams.FilterType = Enum.RaycastFilterType.Include

	local raycastResult = workspace:Raycast(rootPart.Position, dashDirection * maxDashDistance, raycastParams)

	if raycastResult then
		maxDashDistance = (rootPart.Position - raycastResult.Position).Magnitude - 2
	end

	local alignPosition = Instance.new("AlignPosition") 
	alignPosition.ApplyAtCenterOfMass = true
	alignPosition.Mode = Enum.PositionAlignmentMode.OneAttachment
	alignPosition.Attachment0 = rootPart:FindFirstChild("RootAttachment")
	alignPosition.MaxForce = math.huge
	alignPosition.Responsiveness = 200

	local targetPosition = rootPart.Position + dashDirection * maxDashDistance
	targetPosition = Vector3.new(targetPosition.X, rootPart.Position.Y, targetPosition.Z)
	alignPosition.Position = targetPosition

	alignPosition.Parent = rootPart

	task.wait(0.2)
	alignPosition:Destroy()
end

I made sure to nullify the y coordinate of the dashDirection vector

dashDirection = Vector3.new(dashDirection.X, 0, dashDirection.Z).Unit

And i use the rootpart’s y position as the target position:

targetPosition = Vector3.new(targetPosition.X, rootPart.Position.Y, targetPosition.Z)

Any idea why it’s happening?

I had the same problem.

I fixed this by using:

AlignPosition.RigidityEnabled = false
AlignPosition.ForceLimitMode = Enum.ForceLimitMode.PerAxis
AlignPosition.MaxAxesForce = Vector3.new(forceX, 0, forceZ)

A little late. Sorry!

Note: I am using ApplyAtCenterOfMass = true I don’t know if this makes a difference.
