title: Child Trigger event on parent Script
body: <p>I am making a game in Unity3D and I have this situation.</p>
  
  <p>I have a parent with some children. Eg:</p>
  
  <p>Parent:</p>
  
  <ul>
  <li>Child 1 </li>
  <li>Child 2 </li>
  <li>Child 3</li>
  </ul>
  
  <p>On Parent and Child 3 i have the component Box Collider 2D with the property Is Trigger checked.</p>
  
  <p>On the parent i have a script with OnTriggerEnter2D function</p>
  
  <p>But if Child 3 collide with another object it trigger the function on the parent's script.</p>
  
  <p>I don't need to trigger the event when the Child collide.</p>
  
  <p>What I can do?</p>
