Why does this cause the part to move diagonally?

Asked by

I have a part that is anchored and CanCollide true. This is a server script inside of it. It should make the part move forward, but it gradually moves diagonally.

local part = script.Parent
while true do
wait(0.01)
part.CFrame = part.CFrame - Vector3.new(0,0,6)
end

If the part is rotated, it'll make it go diagonally as adding a Vector3 moves it using the global axes. To move it on the local axises, use cf * cf:

part.CFrame = part.CFrame * CFrame.new(-Vector3.new(0,0,6))
-- or
part.CFrame = part.CFrame * CFrame.new(0,0,-6)
