Multi-touch in a unity 2D game

I’m trying to make a 2D android multiplayer game like ping pong.How can i use multi-touch to move paddles on the sides individually.I’m having trouble figuring out the code move both the paddles simultaneously

  1. left = player A, right player B
  2. define the middle as x=0
  3. if mouseposition is >0 it is player B, <0 it is A.
  4. then you teleport the paddle to the position in update.

that is the general concept. you need more help?
