title: Detect long touch
body: <p>I need to detect long touch in the game the game I am trying to make.How can I do so?<br>
  Other problem I am facing is to limit simultaneous touches. i.e the sprite won't jump if user touches more than two times immedeatly one after other.<br>
  Also is their a way by which I can add touch duration factor to the height of jump the sprite makes?  </p>
  
  <p>Thanks</p>
