Unity查找自身為第幾個子物體GetSiblingIndex()

1.API  GetSiblingIndex(); Gets the sibling index

直接掛到 四個按鈕上  即可看到每一個按鈕的索引 (也就是Canvas下面有幾個子物體 索引從0開始)

 

 代碼:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GetChild_ID : MonoBehaviour
{
    public int IDD;
    public  Transform parent;
    // Start is called before the first frame update
    void Start()
    {
        parent = this.transform.parent;
        IDD = this.transform.GetSiblingIndex();
    }
}
