Raycast Get Object Using Empty GameObjects in Hierarchy

For any given transform, you can check its parent all the way up to the top of the hierarchy (at which point the parent will be null).

So, really, the question is: what does "main parent" mean to you? If you can figure that out, just keep going one parent up until you find it.

If your main parent has a unique name and is a direct child of the root you can do:

  var mainParent = transform.root.Find("UniqueName");

Thank you both. I feel like robertbu's answer is a good implementation of rutter's. Thanks again!

This is more what I though @rutter was talking about. If you have multiple main parents collected under an empty game object, this will work better, since it does not require a name:

 function Find$$anonymous$$ainParent(start : Transform) : Transform {
     var parent : Transform;
     var child : Transform = start;
     var curr = start;
 
     while (curr.parent != null) {
          parent = curr.parent;
          child = curr;
          curr = parent;
     }
     
    return child;
 }

Cannot be called form the root.

Huh, calling Find from the root is a nice and quick method, though. I'll have to remember that.
