How can I move a part at constant speed through multiple points?

[Daw588]

I’ve always had an issue with AlignPosition, which is that it doesn’t move at constant speed but rather deaccelerates, reaches the point, and then starts accelerating again, but I want the speed to be constant. How can I achieve this?

alignPosition = Instance.new("AlignPosition")
alignPosition.Attachment0 = bottomAttachment
alignPosition.Mode = Enum.PositionAlignmentMode.OneAttachment
alignPosition.Position = target.WorldPosition
alignPosition.MaxForce = 100_000
alignPosition.MaxVelocity = 25
alignPosition.Responsiveness = 100
alignPosition.Parent = character
	
alignOrientation = Instance.new("AlignOrientation")
alignOrientation.Attachment0 = bottomAttachment
alignOrientation.Mode = Enum.OrientationAlignmentMode.OneAttachment
alignOrientation.MaxTorque = 100_000
alignOrientation.MaxAngularVelocity = 25
alignOrientation.Responsiveness = 25
alignOrientation.Parent = character

You just need to increase the responsiveness to the maximum amount. The other image likely is using CFrame calculations or manually applying force using ApplyImpulse if I’m not mistaken.

I just opted-out of AlignPosition and instead I am going with TweenService + Spline module. Still working on it, so we will see if it will solve my problem.

Just managed to do this with TweenService + Spline function + AlignPosition.

So what I did was generate points with spline function, then tween from point to point an attachment, AlignPosition would just follow the attachment through the attachment1 property.
