The 'specific point' being where it ship is at the time. Sorry that wasn't very clear.

Ok, this makes the smoke no longer attached to the ship and it leaves a trail when up is pressed, BUT, the smoke also leaves the ship entirely, and appears to be keyboard controlled still. All that needs to happen is that the smoke is spawned in the world at a specific point, not relative to the screen, and stays there until it disappears.
