How do make a part move in the direction it is facing

Hello! I want to know how to make a part move in the direction it is facing. I tried using ToWorldSpace() but it only faced in a certain direction but didn’t move there. I also tried bodyVelocity but the direction doesn’t change. Can someone please tell me how to make a part move in the direction it is facing? Thanks!

You can use TweenService and LookVector to accomplish this:

local part = -- Your part here.
local distance = -- Distance the part should move.
local tween = game:GetService("TweenService"):Create(part, TweenInfo.new(1, Enum.EasingStyle.Sine), {CFrame = part.CFrame + (part.CFrame.LookVector * distance)})

tween:Play()

Let me know if this isn’t what you need, or if doesn’t work.

Thank you so much! But I am doing this on the server and tweening will lag. Is there a way to use bodyVelocity to do this?

The same thing, you use the LookVector as the velocity, multiplied by the speed of the velocity using disntance.

Ok. Let me try them and then I will set as solution.

You can use BodyForce

BodyForce.Force = Vector3.new(0, 0, 5000) * part.CFrame.LookVector

You will have to change the force from 5000 to anything you like, It depends on the part you want to move

Also to use Tween without lagging, set the network owner of the part to nil (server)

part:SetNetworkOwner(nil)

How would I do this if I was using bodyVelocity?

You add the bodyVelocity inside a part, set MaxForce and P to what you want.
Then inside the script you should add:

local BodyVelocity = script.parent:WaitForChild("BodyVelocity")
BodyVelocity.Velocity = Vector3.new(0, 0, 5000) * part.CFrame.LookVector

Vector3.new(0, 0, 5000): is the velocity,
* part.CFrame.LookVector will make the part always go forward, or at the direction you want

If you want a specific position, I would recommend Tween Service

I have to go to sleep now. If it worked tomorrow, I will set it as the solution. Thanks again!
