# How to position a part towards one direction no matter where it's facing

I’m tweening something and I want to know if there’s a way to move a part backwards no matter what direction it’s facing.

This very detailed thing I made should explain it better lol

Move backwards relative to what?
The original rotation? The world? Etc

Backwards relative to the part.

Would the rotation of the part be changing mid-tween or would it stay constant until the next tween can start?

The Part’s CFrame contains LookVector which is the forward direction. If you want to always move it backward, use the negative LookVector.

The tween just moves it in one direction… which is backwards…

Tried this and this is what happened. It still moves backwards relative to the world and not the part

``````local function keypress(key)
local down = {CFrame = key.CFrame + key.CFrame.	ZVector * stuff.keyoffset}
remote:FireAllClients(key, stuff.tweeninfo2, down)
end
``````

I know theres supposed to be a minus sign there and not a plus but that still wouldn’t fix the problem.

What is key.CFrame.ZVector?
Is it a custom made value?

When you compose two CFrames you should use the multiplication symbol. It will make it relative to the original matrix.

``````Part.CFrame * CFrame.new(0,0,1) -- Local-space Backwards
``````

Vs

``````Part.CFrame + Vector3.new(0,0,-1) -- World-space backwards
``````

Important to note negative 1 on the Z axis in CFrame multiplication is “forward.” So positive 1 is backwards.
