TweenService acceleration

Hello, I’ve been working on this for a while now. How can I make it so that the speed adjusts slowly instead of immediately. In other words, the car should not increase its speed directly.

		local direction = (destination - Car.Position).unit
		local distance = (destination - Car.Position).magnitude

		local timeToReach = distance / currentPoint.Speed

		local Tween1 = game:GetService("TweenService"):Create(Car, TweenInfo.new(timeToReach, Enum.EasingStyle.Linear), {Position = destination})
		Tween1:Play()

		local lookAt = CFrame.new(Car.Position, destination).lookVector
		local Tween2 = game:GetService("TweenService"):Create(Car, TweenInfo.new(timeToReach, Enum.EasingStyle.Linear), {CFrame = CFrame.new(Car.Position, Car.Position + Vector3.new(lookAt.X, 0, lookAt.Z))})

		Tween2:Play()

		wait(timeToReach)

Modify your TweenInfo. For example

TweenInfo.new(timeToReach, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)

Yes, but it should only accelerate at the start and not slow down again at the end

So you want the car to keep going? Then I guess you should use something like BodyVelocity or LinearVelocity. On the BodyVelocity, tween the .Velocity property to a your needed speed, and it’ll be constantly accelerating.

Can’t you make a better solution with Lerp or something?

I recommend checking this website to see which EasingStyle and EasingDirection is best for you https://easings.net/

Roblox sucks and this could’ve been resolved with custom easing.

Unfortunately, your best bet is to use Ease In graph at the start with tween and make it run continuously, linearly without tween until the end.
