I am trying to create a player movement along the x-axis based on finger position.

**What I need to Happen:** Not multi-Touch. I want it so a player can put a single finger down and grab that position. Then check to see if the player dragged finger along screen on x-axis and move player left or right based off where they dragged finger from first touch.

So if they touch the screen and if drag left: move left by speed and if it changes to drag right move right by speed.

Any help would be Awesome.
