title: cocos2d-x selecting sprites while moving touch
body: <p>I'm new to cocos2d-x 3.6 and trying to make a simple game.</p>
  
  <p>I have a vector of sprites. I want to touch one of them, and then move my finger across the screen and other sprites being selected while I'm touching them. </p>
  
  <p>How can I implement this?</p>
