How to get access to child's objects of instantiated prefab on JS?

Archived Forums Questions & Answers

Have created in “Resources” folder “Body.prefab” and “Obj.prefab”.
Body.Prefab Hirerarchy is

"Body" (GO with mesh)
|_"1st-Dummy" (GO without mesh)
|_"2nd-Dummy" (GO without mesh)
|_"3rd-Dummy" (GO without mesh)
|_"4th-Dummy" (GO without mesh)

need to get after instantiating

"Body" (GO with mesh)
|_Objects (Empty GO)
| |_first
| |_second
| |_third
| |_fourth
|
|_"1st-Dummy" (GO without mesh)
|_"2nd-Dummy" (GO without mesh)
|_"3rd-Dummy" (GO without mesh)
|_"4th-Dummy" (GO without mesh)

use JavaScript to instantiate Body prefab

var Body : GameObject;
var first : GameObject;
var second : GameObject;
var third : GameObject;
var fourth : GameObject;
function Start () {
Body = Instantiate(Resources.Load("Body.prefab", GameObject));
Body.Transform.Position = Vector3.Zero;
Body.Transform.Rotation = Quaternion.identity;

first = Instantiate(Resources.Load("Obj.prefab", GameObject));
}
  1. Can I load prefab and give it another name that propose me unity3d? (It calls “Body(clone)”, I want to call it “Body”)
  2. How Can I set transform position of first variable to child postion of 1st-Dummy of Body instantiated prefab.
  3. How can I to put first variable to be child of Body?

  1. loadedPrefab.name = “Body”;
  2. first.transform.position = Body.FindChild(“1st-Dummy”).position; (Although it would be better to have a direct reference to your dummies.)
  3. first.transform.parent = Body.transform;

  1. first.transform.position = Body.FindChild(“1st-Dummy”).position; (Although it would be better to have a direct reference to your dummies.)
    Doesn’t work. Show’s me error that can fing in UnityEngine “FindChild”

first.transform.position = Body.transform.Find("1st-Dummy").position;

hi.
i think this is the best way to access to the child of a prefab that instantiated.

using UnityEngine;
using System.Collections;

public class CreatNewPlanet : MonoBehaviour {
public Transform myprefab;

private Transform NewGameObject;
TextMesh xmesh=new TextMesh();
// Use this for initialization
void Start () {

}
bool clicked=false;
// Update is called once per frame
void Update () 
{
	if(!clicked)
	{
	if(Input.GetKey(KeyCode.T))
	{

		NewGameObject=Instantiate(myprefab,new Vector3(12,-3,0),Quaternion.identity) as Transform;
			clicked=true;
			print(NewGameObject.GetChild(4).name);
			xmesh=NewGameObject.GetChild(4).GetComponent(typeof(TextMesh)) as TextMesh;

			xmesh.color=Color.blue;
			xmesh.text="------X:"+ ((int)(NewGameObject.GetChild(3).transform.position.x)) .ToString ();

		}

	
}


}
