unity游戏开发飞机大战作业（附代码）

首先只要按图摆放好对应组件

在unity2d项目运行

代码：按图片从左往右

1.

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

public class Bullet1: MonoBehaviour {

    // Use this for initialization
    void Start () {
        Destroy(gameObject, 2);
    }
    
    // Update is called once per frame
    void Update () {
        transform.Translate(Vector3.up * 20 * Time.deltaTime);
    }
}

2.

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

public class Enesy_s1 : MonoBehaviour {

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        transform.Translate(Vector3.down * 2 * Time.deltaTime);
        if (transform.position.y < -5)
        {
            float x = Random.Range(-7.1f, 8.8f);
            transform.position = new Vector3(x,
                9, -0.3f);
        }
    }
}

3.

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

public class firee : MonoBehaviour {
    public GameObject m_Bullet;
    public Transform m_ttt;
    // Use this for initialization
    void Start () {
        
    }
    private void move()
