Unity查找子物体/脚本

1、查找子物体：主要应用在，当子物体是隐藏状态时Find不到的情况
2、查找脚本：只要有父物体和挂载脚本物体的名字即可

using UnityEngine;
using System.Collections;

public abstract class Global
{
    
    
    /// <summary>
    /// 查找子物体
    /// </summary>
    /// <param name="trans">父物体</param>
    /// <param name="childName">子物体名</param>
    /// <returns></returns>
	public static GameObject FindChild(Transform trans , string childName)
	{
    
    
		Transform child = trans.Find(childName);
		if (child != null)
		{
    
    
			return child.gameObject;
		}
		int count = trans.childCount;
		GameObject go = null;
		for(int i = 0 ; i < count ; ++i)
		{
    
    
			child = trans.GetChild(i);
			go = FindChild(child, childName);
			if (go != null)
				return go;
		}
		return null;
	}

	public static T FindChild<T>(Transform trans, string childName) where T : Component
	{
    
    
		GameObject go = FindChild(trans,childName);
		if(go == null)
			return null;
		return go.GetComponent<T>();
	}
