title: 'Slider Control' kind of controls in Cocos2d help
body: <p>I am making a game in Cocos2d. I want there to be a dotted line that follows the user's finger. I want the line to be straight. The problem is, how do I check to see how many 'dots' will fit in the distance between the ball and where the user is touching? And make it follow in a STRAIGHT line between the ball's position and the finger's position? So here's a re-clarification:</p>
  
  <p>The ball sits still on the left side of the screen, and is halfway up the screen. The user drags their finger, and a dotted line is drawn between the ball's position and the touch's position. I have a 'dot' image to be used, and I would like it to be used as the dots in the line. So it will have to recreate the sprite as many times as it will fit in the area between the two points. Please tell me if you want me to clarify further, Thanks!!</p>
