title: How to set prefab children's components on a script from inspector?
body: <p>I am new to Unity!</p>
  
  <p>I have a player prefab with this tree:
  <a href="https://i.stack.imgur.com/rzqgC.png" rel="nofollow noreferrer">Player tree</a>
  Each item has a BoxCollider2D component</p>
  
  <p>I also have a wall prefab with this script:
  <a href="https://i.stack.imgur.com/CmMBH.png" rel="nofollow noreferrer">Wall Script</a></p>
  
  <p>What I want to do is set the collider of topCol as the Up Collider variable, the collider of downCol as the Down Collider variable and so on...
  I can't seem to figure out how to do it in the inspector, because it seems like I can only select the player prefab boxcollider2d component and not the children ones!</p>
  
  <p>I am aware I can retrieve those components via script, I am just wondering if I can do it just via inspector!</p>
  
  <p>Thank you for reading :D</p>
