Making this part move forwards

[FroDev1002 (FroDev)]

Im currently working on a Projectile System and I created this:

	RunService.Heartbeat:Connect(function(DeltaTime:number)
		for _, Object in Projectiles do
			-- // Move //
			if Object.Health > 0 and Object.Part then
				if not Object.Part.Parent then continue end
				
				local Direction:CFrame = Directions[Object.Direction] or Directions.Forwards
				local Speed = Object.Speed * DeltaTime
				local TravelTo = (Direction * CFrame.new(Speed, Speed, Speed))
				
				-- // Move //
				if Object.Distance > Object.Range then
					-- // Drop Off //
					
				end
				
				
				Object.Part.CFrame *= TravelTo
				Object.Hitbox:CheckForCollisions()
			end
		end
	end)

the idea is that it should move the Object.Part forwards.
The problem is that they kinda go up and to the side, I assume I did something wrong with the TravelTo CFrame, as when the speed is 0, making the TravelTo just a blank CFrame, it works perfectly fine.

So how can I fix this?

Also, these are the Direction that are mentioned in the script

return {
	['Forwards'] = CFrame.new(0,0,-1),
	['Backwards'] = CFrame.new(0,0,1)
}

Hello!

You might have the orientation incorrect. To check this you can right click a part and click “Show Orientation Indicator.”

The result will look something like this:

from my experience Z is forwards when it comes to CFrames, and well their CFrames, so the rotation wouldnt effect it, it would still move well, forwards.

Wait I think I just figured it out. using the * doesnt multiply, it adds, which would mess it up. Lemme go see if this is the case

Ok that was in fact the issue, thanks for trying to help though!
