2、将素材全部拉进去

3、创建新的场景

并且将场景添加到build settings里面

4、脚本

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

public class StartBtnLis : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    //监听鼠标按下
    private void OnMouseDown()
    {
    	//对象比例缩小
        transform.localScale = transform.localScale * 0.8f;
    }
    //监听鼠标松开
    private void OnMouseUp()
    {
    	//对象比例放大
        transform.localScale = transform.localScale / 0.8f;
        //场景切换
        SceneManager.LoadScene("game");
    }
}

5添加脚本

将c#脚本长按拉动到对应指定的图层就会把脚本添加进去

6、添加2d盒装碰撞器

7、测试运行

点击按钮则能看到按钮动态缩小并跳转到对应的场景
