How to make a moving part retain speed between points

Help and Feedback Scripting Support

Basically I have a part “Move” in game.Workspace and 3 points “Point1” “Point2” “Point3”
I have script to move a part between the 3 points, but for each point it slows down
I want it so that the moving Part retains the same speed, while following the path of point 2, but still slows down at point 3

local TweenService = game:GetService("TweenService")
local movePart = script.Parent
local point1 = workspace:WaitForChild("Point1")
local point2 = workspace:WaitForChild("Point2")
local point3 = workspace:WaitForChild("Point3")
local points = { point1, point2, point3 }
local tweenInfo = TweenInfo.new(7.5, Enum.EasingStyle.Sine, Enum.EasingDirection.InOut) --,0, false, 0
local function moveToNextPoint()
	while true do
		for i = 1, #points do
			local goal = { Position = points[i].Position }
			local goalO = { Orientation = points[i].Orientation }
			local tween = TweenService:Create(movePart, tweenInfo, goal)
			local tween2 = TweenService:Create(movePart, tweenInfo, goalO)
			tween:Play()
			tween2:Play()
			tween.Completed:Wait(0.5)
			if i == 2 then
				local targetCF = CFrame.new(points[i].Position) * CFrame.new(0, 0, 0)
				movePart.CFrame = movePart.CFrame:Lerp(targetCF, 0)
			end
		end
	end
end
moveToNextPoint()

You need a different TweenInfo for start, middle, and end tweens. The start/end bit needs to use EasingDirection.Out or EasingDirection.In, the others use InOut. I think the EasingStyle you need for the middle pieces is Linear.

One way you could achieve this effect would be through something called Lerping. I personally don’t know much about it as its not commonly used, though I know what it does. It allows for tweening sort of like what you’re doing between points at the same speed. I’d look it up and watch a tutorial on how to lerp something.
