public int GetSiblingIndex ();


Obtiene el indice del hermano.

Use this to return the sibling index of the GameObject. If a GameObject shares a parent with other GameObjects and are on the same level (i.e. they share the same direct parent), these GameObjects are known as siblings. The sibling index shows where each GameObject sits in this sibling hierarchy.

Use GetSiblingIndex to find out the GameObject’s place in this hierarchy. When the sibling index of a GameObject is changed, its order in the Hierarchy window will also change. This is useful if you are intentionally ordering the children of a GameObject such as when using Layout Group components.

Layout Groups will also visually reorder the group by their index. To read more about Layout Groups see AutoLayout. To set the sibling index of a GameObject, see Transform.SetSiblingIndex.

//This script demonstrates how to return (GetSiblingIndex) and change (SetSiblingIndex) the sibling index of a GameObject.
//Attach this script to the GameObject you would like to change the sibling index of.
//To see this in action, make this GameObject the child of another GameObject, and create siblings for it.

using UnityEngine;

public class TransformGetSiblingIndex : MonoBehaviour { //Use this to change the hierarchy of the GameObject siblings int m_IndexNumber;

void Start() { //Initialise the Sibling Index to 0 m_IndexNumber = 0; //Set the Sibling Index transform.SetSiblingIndex(m_IndexNumber); //Output the Sibling Index to the console Debug.Log("Sibling Index : " + transform.GetSiblingIndex()); }

void OnGUI() { //Press this Button to increase the sibling index number of the GameObject if (GUI.Button(new Rect(0, 0, 200, 40), "Add Index Number")) { //Make sure the index number doesn't exceed the Sibling Index by more than 1 if (m_IndexNumber <= transform.GetSiblingIndex()) { //Increase the Index Number m_IndexNumber++; } }

//Press this Button to decrease the sibling index number of the GameObject if (GUI.Button(new Rect(0, 40, 200, 40), "Minus Index Number")) { //Make sure the index number doesn't go below 0 if (m_IndexNumber >= 1) { //Decrease the index number m_IndexNumber--; } } //Detect if any of the Buttons are being pressed if (GUI.changed) { //Update the Sibling Index of the GameObject transform.SetSiblingIndex(m_IndexNumber); Debug.Log("Sibling Index : " + transform.GetSiblingIndex()); } } }
