Unity之GameObject类_unity gamobject.find

GameObject.Find:

    用于查找游戏对象，我们结合代码进行理解：
1

GameObject  cube;
cube=GameObject.Find("Cube");//在场景中找到Cube对象并把它赋给cube
1
2

GameObject.FindWithTag:

这个方法也是用来找游戏对象的，只不过是根据游戏对象的tag来匹配的。

GameObject.FindGameObjectWithTag

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

public class GameObjectGameOGjectWithTag : MonoBehaviour
{
    GameObject[] myObjects;
    // Start is called before the first frame update
    void Start()
    {
        myObjects = GameObject.FindGameObjectsWithTag("ObjectTag");
       foreach (GameObject o in myObjects)
        {
            Debug.Log(myObjects [1].name );//将Tag为ObjectTag的物体一一赋值给myObjects
        }
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

GetCompoment<>()方法

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

public class GetCompoment : MonoBehaviour
{
    GameObject CubeObject;
    private MeshFilter meshFilter;//定义了一个MeshFilter类型的变量，用于保存相关的组件

    // Start is called before the first frame update
    void Start()
    {

        CubeObject = GameObject.Find("Cube");
        CubeObject.AddComponent<Rigidbody>();//给Cube加了一个刚体组件。
        meshFilter = CubeObject.GetComponent<MeshFilter>();//获得Cube的MeshFilter的组件
        Debug.Log(meshFilter.mesh);//打印出该组件的相关mesh材质。
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}
