Unity3D_(游戏)双人3D坦克_简易版

 

 

双人3D坦克实现

　　

　　player1: WSAD控制上下左右 　　空格键发射炮弹

　　player2: IKJL可控制上下左右　　B键发射炮弹 

　　每个坦克只有100hp,子弹击中1次扣30hp，hp时时显示在坦克上

 　  当一辆坦克hp低于0时，游戏结束

　　Main Camera聚焦两辆坦克中心点　　　

 

　　游戏项目已托管到github上(里面有个32bit可执行文件)　　传送门

　　　　(官方demo 素材包有点大。。)

 

游戏界面

 

     (觉得子弹射程短，可以适当提高游戏子弹速度)

        p = target - transform.position;

            //找到两个坦克的中点

实现过程

　　

 

创建场景

 

　　导入坦克资源场景

　　

　　

    Lightmapping光照贴图技术是一种增强静态场景光照效果的技术，其优点是可以通过较少的性能消耗使静态场景看上去更加真实，丰富，更加具有立体感；缺点是不能用来实时地处理动态光照。当游戏场景包含了大量的多边形时，实时光源和阴影对游戏的性能的影响会很大。这时使用Lightmapping技术，将光线效果预渲染成贴图使用到多边形上模拟光影效果。

　　加载光照贴图有时候会造成场景卡顿

　　　　Auto Generate　　：设置成不自动生成

　　　　Generate Lighting　　：生成一次场景光照

 

 

坦克的前后移动

 

　　添加坦克预设体进入游戏场景，DustTrail粒子特效预设体放到坦克上

　　(GameObject ->Align  With View 将Game视图对准当前Scene视图)

 

　　给坦克添加碰撞器和刚体

　　（碰撞器慢慢移，拖动数值调整到刚好包围完坦克）

 

 

　　添加移动坦克脚本

 

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

public class Movement : MonoBehaviour {

    public float speed = 5;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {

        //获得玩家的键盘输入
        float v = Input.GetAxis("Vertical");
        //让坦克前后移动
        GetComponent<Rigidbody>().velocity = transform.forward * v * speed;


    }
}

 

　　设置坦克移动速度

  public float speed = 5;

 

　　获得玩家的键盘输入

float v = Input.GetAxis("Vertical");

 

　　让坦克前后移动

GetComponent<Rigidbody>().velocity = transform.forward * v * speed;

 

　　(将相机放到坦克里面，实现相机和坦克一起移动)

 

 

坦克的旋转

 

　　查看Unity输入按键值

　　水平移动：Vertical

　　左右移动：Horizontal

 

 

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

public class Movement : MonoBehaviour {

    public float speed = 10;
    public float angularSpeed = 5;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        //获得玩家的键盘输入
        float v = Input.GetAxis("Vertical");
        float h = Input.GetAxis("Horizontal");
       
        //让坦克前后移动
        GetComponent<Rigidbody>().velocity = transform.forward * v * speed;
        GetComponent<Rigidbody>().angularVelocity = transform.up * h * angularSpeed;

    }
}

 

　　设置坦克移动转动角速度

  public float angularSpeed = 5;

 

　　获得玩家的键盘输入

 float h = Input.GetAxis("Horizontal");

 

　　让坦克前后移动

GetComponent<Rigidbody>().angularVelocity = transform.up * h * angularSpeed;

 

 

　　为实现双人坦克效果，提高按键灵活性，在InputManager管理器中添加两个Axes

　　修改Axes值Horizontal1、Horizontal2、Vertical1、Vertical2

　　　　

 

我把玩家二上下左右WSAD按键修改为IKJL,实现双人笑游戏效果

 

　　默认角色是1号玩家

       public string player = "1";

        //获得玩家的键盘输入
        float v = Input.GetAxis("Vertical"+player);
        float h = Input.GetAxis("Horizontal"+ player);
           

 

　　新建双人坦克修改Player值

 

 

 

 

坦克子弹

 

　　给子弹添加刚体和碰撞器

　　(将子弹设置为预设体，保存到Gary文件夹中)

 

　　给坦克添加一个空物体,每次坦克都是从这个点动态生成子弹发射出去的

 

　　添加Shoot脚本，挂载到坦克物体上

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

public class Shoot : MonoBehaviour {

    public GameObject shell;
    Transform pos;

    // Use this for initialization
    void Start () {
        //找到子对象
        pos = transform.Find("FirstPosition");
    }
    
    // Update is called once per frame
    void Update () {
        //按下一个按键
        if (Input.GetKeyDown(KeyCode.Space))
        {
            //发射子弹 实例化
            Instantiate(shell,pos.position,pos.rotation);
        }
     

    }
}

 

　　引用子弹实例化

 public GameObject shell;

 

　　找到子弹发射的位置

 pos = transform.Find("FirstPosition");

 

　　按下一个按键,，将子弹实例化

        if (Input.GetKeyDown(KeyCode.Space))
        {
            Instantiate(shell,pos.position,pos.rotation);
        }

 

 

 

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

public class Shoot : MonoBehaviour {

    public GameObject shell;
    Transform pos;

    public KeyCode key = KeyCode.Space;

    // Use this for initialization
    void Start () {
        //找到子对象
        pos = transform.Find("FirstPosition");
    }
    
    // Update is called once per frame
    void Update () {
        //按下一个按键
        if (Input.GetKeyDown(key))
        {
            Instantiate(shell,pos.position,pos.rotation);
        }

    }
}

 

　　在外添加一个key，按任意键可以射出子弹

     public KeyCode key = KeyCode.Space;

        //按下一个按键
        if (Input.GetKeyDown(key))
        {
            Instantiate(shell,pos.position,pos.rotation);
        }    

 

 

　　定义子弹发射速度

 public float speed = 180;

 

　　按下一个按键，子弹发射出去

        if (Input.GetKeyDown(key))
        {
            GameObject go = Instantiate(shell,pos.position,pos.rotation);
            go.GetComponent<Rigidbody>().velocity = go.transform.forward * speed;
            go.GetComponent<Rigidbody>().velocity = Vector3.forward * speed;
        }

 

 

子弹爆炸动画

 

　　添加脚本shell，挂载到子弹物体对象上

 

    private void OnCollisionEnter(Collision collision)
    {
        Destroy(gameObject);
    }

 

　　当子弹碰到刚体时销毁自己

 

　　添加子弹碰到物体触发爆炸效果

 

　　引用粒子特效

public GameObject ex;

 

   private void OnCollisionEnter(Collision collision)
    {
        Destroy(gameObject);
        GameObject go = Instantiate(ex,transform.position,transform.rotation);
    }

 

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

public class Shell : MonoBehaviour {

    public GameObject ex;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        
    }

    private void OnCollisionEnter(Collision collision)
    {
        Destroy(gameObject);
        GameObject go = Instantiate(ex,transform.position,transform.rotation);
    }
}

 

 

子弹血量的减少

 

　　给坦克添加标签

 

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

public class TankHealth : MonoBehaviour {

    public int hp = 100;
    public GameObject ex;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        
    }

     public void TakeDamage()
    {
        hp -= 30;
        if (hp < 0)
        {
            Destroy(gameObject);
            GameObject go = Instantiate(ex, transform.position, transform.rotation);
        }
    }

}

 

　　初始化血量hp=100

 public int hp = 100;

 

　　设置坦克爆炸粒子效果

  public GameObject ex;

 

　　当血量低于0时，坦克销毁，爆炸粒子效果出现

    public void TakeDamage()
    {
        hp -= 30;
        if (hp < 0)
        {
            Destroy(gameObject);
            GameObject go = Instantiate(ex, transform.position, transform.rotation);
        }
    }

 

 

 

相机跟随

 

　　将照相机改为正交

 

　　在摄像机中添加并挂载FollowCameral脚本

 

　　两个坦克的引用

    public GameObject tank1;
    public GameObject tank2;

 

　　两个坦克之间的中点

    Vector3 p;

　　 Vector3 target=(tank1.transform.position + tank2.transform.position) / 2;
    p = target - transform.position;

 

　　计算出两个坦克之间的距离

 transform .position= (tank1.transform.position + tank2.transform.position) / 2 - p;

 

　　找到两个坦克的中点并让摄像机对准中心点，根据两点之间的距离，调整摄像机的尺寸

        float distance = Vector3.Distance(tank1.transform.position,tank2.transform.position);
        GetComponent<Camera>().orthographicSize = distance * size+ 2f;

 

 

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

public class FollowCamera : MonoBehaviour {

    public GameObject tank1;
    public GameObject tank2;
    public float size= 0.58f;

    Vector3 p;

    // Use this for initialization
    void Start () {
        Vector3 target=(tank1.transform.position + tank2.transform.position) / 2;
        p = target - transform.position;
     }
    
    // Update is called once per frame
    void Update () {
        //计算出两个坦克之间的距离
        transform .position= (tank1.transform.position + tank2.transform.position) / 2 - p;

        //找到两个坦克的中点
        //让摄像机对准中心点
        //根据两点之间的距离，调整摄像机的尺寸
        float distance = Vector3.Distance(tank1.transform.position,tank2.transform.position);
        GetComponent<Camera>().orthographicSize = distance * size+ 2f;


    }
}

 

 

添加音效

 

　　在Main Camera上绑定Audio Source音乐播放器

 

 

血条

 

　　创建一个Slider,把Canvas移动到坦克上

　　设置Slider控件的 PosX=0 PosX=0 PosZ=0

 

 

　　参数下如下配置

 

 

 

　　设置完成后效果如下

 

　　设置成垂直

 

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

public class TankHealth : MonoBehaviour {

    public int hp = 100;
    public GameObject ex;
    public Slider slider;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        
    }

    public void TakeDamage()
    {
        hp -= 30;
        if (hp < 0)
        {
            Destroy(gameObject);
            GameObject go = Instantiate(ex, transform.position, transform.rotation);
        }
        slider.value = hp;

    }

}

 

　　添加Slider控件

 public Slider slider;

 

　　坦克攻击时，时时刷新slider.value值

    public void TakeDamage()
    {
        hp -= 30;
        if (hp < 0)
        {
            Destroy(gameObject);
            GameObject go = Instantiate(ex, transform.position, transform.rotation);
        }
        slider.value = hp;

    }
