1、给地面，柱体这种添加2d盒装碰撞器，小鸟移动碰到就不会动了

在这里插入图片描述

2、修改小鸟的脚本（脚本命名不规范，不要在意）

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

public class Fly : MonoBehaviour
{
    //获取小鸟（刚体）
    private Rigidbody2D bird;
    //速度
    public float speed;
    //跳跃
    public float jump;
    //是否存活
    public static bool life = true;
    //获取动画器
    private Animator animator;

    // Start is called before the first frame update
    void Start()
    {
        bird = GetComponent<Rigidbody2D>();
        animator = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        //存活的时候才能运动
        if (life) { 
            bird.velocity = new Vector2(speed, bird.velocity.y);
            //鼠标点击给目标一个纵向速度
            if (Input.GetMouseButtonDown(0))
            {
                bird.velocity = new Vector2(bird.velocity.x, jump);
            }
        }
    }
    //如果碰撞器撞到了某个物体
    private void OnCollisionEnter2D(Collision2D collision)
    {
    	//死亡
        life = false;
        //向动画器传送为life的参数
        animator.SetBool("life", false);
    }
}
