    16.     {
    17.         float moveX = Input.GetAxisRaw("Horizontal");//控制水平移动方向 A:-1  D:1  不按: 0
    18.         float moveY = Input.GetAxisRaw("Vertical");//控制垂直移动方向 W:-1  S:1  不按: 0
    19.  
    20.         Vector2 position = transform.position;//定义角色位置向量
    21.         position.x += moveX * speed * Time.deltaTime;
    22.         position.y += moveY * speed * Time.deltaTime;
    23.         transform.position = position;//将位置信息传输给角色
    24.  
    25.         bullet.transform.position = transform.position;//将角色信息传输给子弹
    26.         
    27.         if (Input.GetKeyDown(KeyCode.Space))//按下空格键
    28.         {
    29.             Instantiate(bullet);//生成子弹预制体
    30.         }
    31.     }
    32. }

    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4.  
    5. public class bulletMove : MonoBehaviour
    6. {
    7.     public float speed = 5f;//子弹飞行速度
    8.     public float DestroyTime = 5f;//子弹最大飞行时间
    9.     // Start is called before the first frame update
    10.     void Start()

    12.         Destroy(gameObject, DestroyTime);
    13.     }
    14.  
    15.     // Update is called once per frame
    16.     void Update()
    17.     {
    18.         transform.Translate(transform.up * speed * Time.deltaTime);
    19.     }
    20. }

    5、制作敌人

    11.     {
    12.         Destroy(gameObject, DestroyTime);
    13.     }
    14.  
    15.     // Update is called once per frame
    16.     void Update()
    17.     {
    18.         transform.Translate(-transform.up * speed * Time.deltaTime);
    19.     }
    20. }

     Enemy02：蛋哥

    敌人特性：发射子弹。

    导入素材：

    添加碰撞盒和物理系统

    用空子件设置子弹发射位置

    制作预制体子弹

    挂载脚本：

    17.     {
    18.         transform.Translate(transform.up * speed * Time.deltaTime);
    19.     }
    20. }

    设置速度

     敌人脚本：

    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4.  
    5. public class Enemy_1 : MonoBehaviour
    6. {
    7.     public float speed = 7f;
    8.     public float DestroyTime = 10f;
    9.     public GameObject bullet;//子弹
    10.     public GameObject gun;
    11.     public int num = 0;//子弹数量
    12.     // Start is called before the first frame update
    13.     void Start()

    30.             num--;
    31.         }
    32.     }
    33. }

     挂载组件：

    运行：

    6、设置随机生成敌人

     设置一个GameMassage挂载主要脚本：

    随机生成脚本：

    1.   public GameObject[] Enemy;//创建预制体数组
    2.     float timer = 0;//计时器
    3.  
    4. Instantiate(Enemy[Random.Range(0, Enemy.Length)], new Vector2(-Random.Range(-8, 10), Random.Range(7, 10)), Quaternion.identity);

    Enemy[Random.Range(0, Enemy.Length)]：随机生成数量0~数组长度

    new Vector2(-Random.Range(-8, 10), Random.Range(7, 10))：随机生成范围x:-8~10，y:7~10

    Quaternion.identity:不设置旋转

    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4.  
    5. public class gamemanage : MonoBehaviour
    6. {
    7.     public GameObject[] Enemy;
    8.     float timer = 0;//计时器
    9.     // Start is called before the first frame update
    10.     void Start()
    11.     {
    12.         
    13.     }
    14.  
    15.     // Update is called once per frame
    16.     void Update()
    17.     {
    18.         timer += Time.deltaTime;
    19.         //三秒生成一个
    20.         if (timer >= 3)
    21.         {
    22.             Instantiate(Enemy[Random.Range(0, Enemy.Length)], new Vector2(-Random.Range(-8, 10), Random.Range(7, 10)), Quaternion.identity);
    23.             timer = 0;//计时器归零
    24.         }
    25.     }
    26. }

    下载

    效果：

    接下来再给物体添加上碰撞函数就好了：

     勾选Trigger

     添加碰撞销毁函数

    1.  private void OnTriggerEnter2D(Collider2D collision)
    2.     {
    3. 		Destroy(gameObject);
    4. 		Destroy(collision.gameObject);
    5. 	}

    7、对游戏的一些优化：

    给发射子弹的敌人增加计时器，按一定的时间间隔发射。

    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4.  
    5. public class Enemy_1 : MonoBehaviour
    6. {
    7.     public float speed = 7f;
    8.     public float DestroyTime = 10f;
    9.     public GameObject bullet;//子弹
    10.     public GameObject gun;
    11.     float timer=0;
    12.     // Start is called before the first frame update
    13.     void Start()
    14.     {
    15.         Destroy(gameObject, DestroyTime);
    16.     }
    17.  
    18.     // Update is called once per frame
    19.     void Update()
    20.     {
    21.         bullet.transform.position = gun.transform.position;//将角色信息传输给子弹
    22.         timer += Time.deltaTime;
    23.         if (timer >= 1)
    24.         {
    25.             Instantiate(bullet);//生成子弹预制体
    26.             timer = 0;
    27.         }
    28.         transform.Translate(-transform.up * speed * Time.deltaTime);
    29.     }
    30. }

    给敌机添加拖尾：

     

    对子弹进行差别性攻击:

    我方子弹攻击敌人：

    1. //敌人的子弹
    2.  private void OnTriggerEnter2D(Collider2D collision)
    3.     {
    4.         if(collision.tag=="Player")
    5.         {
    6.             Destroy(gameObject);
    7.             Destroy(collision.gameObject);
    8.         }
    9.     }
    10.  
    11. //自己的子弹
    12. private void OnTriggerEnter2D(Collider2D collision)
    13.      {
    14.         if (collision.tag == "Enemy")
    15.         {
    16.             Destroy(gameObject);
    17.             Destroy(collision.gameObject);
    18.         }
    19.     }

     差别性死亡：

    靠刚体重力飞行的敌人：
     

    1. if (collision.tag == "Enemy")
    2.         {
    3.             //更换爆炸图片
    4.             SpriteRenderer spr = collision.GetComponent();
    5.             Sprite sp = Resources.Load("booom");
    6.             spr.sprite = sp;
    7.            
    8.             //停止运动
    9.             collision.GetComponent().Sleep();
    10.             Destroy(gameObject);
    11.             Destroy(collision.gameObject, diedtime);
    12.         }

    靠脚本飞行的敌人：

    1.  public Enemy_1 enemy2;//获取角色移动脚本组件
    2.  
    3. void Awake()//游戏开始前打开脚本功能
    4.     {
    5.         enemy2.enabled = true;
    6.     }
    7.  
    8. //碰撞时处理
    9.  if (collision.tag == "Enemy2")
    10.         {
    11.             //更换爆炸图片
    12.             SpriteRenderer spr = collision.GetComponent();
    13.             Sprite sp = Resources.Load("booom");
    14.             spr.sprite = sp;
    15.  
    16.             //停止运动
    17.             enemy2.enabled = false;
    18.             Destroy(gameObject);
    19.             Destroy(collision.gameObject, diedtime);
    20.             enemy2.enabled = true;
    21.         }

    敌方子弹打中我方或者敌人撞到我方飞机：

    1. if(collision.tag=="Player")
    2.         {
    3.  
    4.             //更换爆炸图片
