title: How to get Direction after cueBall collide with any ball in unity3d?
body: <p>I am creating one pool table unity game. I want to get the direction of ball to show user where the ball will move. Consider the following image for an example.</p>
  
  <p><img src="https://i.stack.imgur.com/MCZZy.jpg" alt=""></p>
  
  <p>Here A is our cueBall and B is ball on the table. Let's consider that when user hit ball A in the direction as per "DIR 1" it will hit to ball B at that time ball A will be at the position of C as per image.</p>
  
  <p>Now I want to know there point</p>
  
  <ol>
  <li>How to find position of c.</li>
  <li>What is the touch point of B &amp; C means which place A will collide with B.</li>
  <li>In which direction ball B will move after collide by A.</li>
  </ol>
  
  <p>I hope this Question is clear to all and provide proper detail for my problem.</p>
