I am trying to build a roller coaster, but I want the velocity to go in the direction of the track. I have tested it, but I do not go in the right direction. I am using lookVector, but that may not be it. Here is the script.
wait(1)
script.Parent.Velocity = Vector3.new(0,0,0)
print(script.Parent.CFrame.lookVector)
script.Parent.RotVelocity = script.Parent.CFrame.lookVector*script.Parent.Parent.LSPeed.Value
Thank you, and have a nice day.

Please elaborate what you mean by, "Try applying the lookVector to Velocity." Becasue if you are saying instead of doing RotVelocity, just do Velocity, that was the first thing i tried, and it did the same thing.
So basically the new script would be just without RotVelocity?
