Question by Diet-Chugg · Oct 10, 2010 at 05:46 AM · parentchild

Parent's Parent and Child's Child Question

how would you access the Parent's parent or the Child's child?

For example your Hierarchy is set up as:

Level
   Player
     Graphics
     Main Camera
     Weapon
       Dagger
       Gun

and I wanted my Weapon to be able to access some variable from my level object's Singleton's script. How would I do that?

Also how would I access it the other way around if my level needs to access my Main Camera's "CutScene" Script?

Also say I want my Gun to access my player's Graphics's "ChangeColor" Script?

So mainly I want to know thoroughly how the parenting system works so I can take advantage of it's full potential.

Singleton s = transform.parent.parent.GetComponent("Singleton"); //OR transform.root.GetComponent("Singleton"); //if you know it will be the top-level object in the hierarchy always s.DoSomething();

CutScene cs = GetComponentInChildren("CutScene"); cs.DoSomething(); ChangeColor cc = GetComponentInChildren("ChangeColor"); cc.DoSomething();

The parent's parent is transform.parent.parent. Accessing "main camera" from "level" would be transform.Find("Player/Main Camera").

using root for the first level hierarchy or recursively reading the child could work too, simple (untested) example:

Transform[] transforms = Selection.GetTransforms(Selection.Deep);

foreach(Transform t in transforms)

if(t.hasChildren){

   <blockquote>
     <p>print("hello, I'm " + t + ", I have " + t.childCount + " children");</p>
   </blockquote>
 </blockquote>
 
 <p>}</p>
