Unity3d实现Flappy Bird游戏

本文实例为大家分享了unity3d实现flappy bird的具体代码，供大家参考，具体内容如下

一、小鸟

在游戏中，小鸟并不做水平位移，而是通过障碍物的移动让小鸟有水平运动的感觉，小鸟只需要对鼠标的点击调整竖直加速度就可以了，同时加上水平旋转模仿原版的flappybird的运动。同时，还要对竖直位置进行判断，否则游戏不能正常结束。

这里贴上小鸟上附加的脚本代码

player.cs

using unityengine;
using system.collections;
 
public class player : monobehaviour {
 
 
 private rigidbody body;
 public vector3 jumpforce = new vector3(0, 300, 0);
 private bool state = true; //确保只执行一次
 private int bestscore = 0;
 
 // use this for initialization
 void start () {
  
  body = transform.getcomponent<rigidbody>();  
 }
 
 void oncollisionenter(collision collisioninfo)
 {
  if (state)
  {
   //碰撞游戏结束
   state = false;
   score.instance.state = false;
   audiomanager.instance.playhit();
   audiomanager.instance.playdie();
   invoke("endgame", 0.4f);
  }
  
  
 }
 
 // update is called once per frame
 void update () 
 {
  //下限
  if (transform.position.y < -20)
  {
   if (state)
   {
    state = false;
    score.instance.state = false;
    audiomanager.instance.playdie();
    invoke("endgame", 0.4f);
   }
  }
 
  //上限
  if (transform.position.y > 20)
  {
   if (state)
   {
    state = false;
    score.instance.state = false;
    audiomanager.instance.playdie();
    invoke("endgame", 0.4f);
   }
  }
  //判断鼠标左键点击或者空格
  if (input.getkeydown(keycode.space)||input.getmousebuttondown(0))
  {
   audiomanager.instance.playfly();
   body.velocity = vector3.zero;
   //加速度
   body.addforce(jumpforce);
   //控制旋转量
   this.transform.rotation = quaternion.euler(45, 270, 0);
  }   
  else
  {
    //旋转
   if (transform.rotation.eulerangles.x >= 280||transform.rotation.eulerangles.x<=50)
   {
    
    transform.rotate(-150 * time.deltatime, 0, 0);
   }
  }
 
 }
 
 public void endgame()
 {
  //保存最佳成绩
  playerprefs.setint("playerscore", score.instance.score);
  bestscore = playerprefs.getint("playerbestscore");
  if (score.instance.score > bestscore)
   bestscore = score.instance.score;
  playerprefs.setint("playerbestscore", bestscore);
  //跳转到结束场景
  application.loadlevel("end");
 }
 
}

二、障碍物

障碍物只要定时产生，随机设定偏移量，然后添加向左运动的速度就行了，同时要设定自动销毁的时间，回收障碍物，否则内存占用会越来越大。

这里用了三个脚本，分别是上下障碍物和障碍物生成脚本。附加到一个空物体上就行了。

generateobstacle.cs

using unityengine;
using system.collections;
 
public class genrateobstacle : monobehaviour {
 
 public gameobject obstacle;
 public gameobject obstacle1;
 public float starttime = 1f;
 public float gaptime=1.5f;
 public float gapdistance = 13;
 private vector3 gapvector;
 private vector3 midvector;
 // use this for initialization
 void start () {
  invokerepeating("initiateobstacle", starttime, gaptime);
  gapvector = new vector3(0, gapdistance / 2, 0);
  
 }
 
 void initiateobstacle()
 {
  midvector = new vector3(8,random.range(-3.2f, 3.2f),0);
 
  instantiate(obstacle, midvector+gapvector,new quaternion(0,0,180,0));
  instantiate(obstacle1, midvector-gapvector, quaternion.identity);
  
 }
}

obstacle.cs

using unityengine;
using system.collections;
 
public class obstacle : monobehaviour {
 
 public float speed = -8f;
 private rigidbody body;
 private transform player;
 private bool ispassed = false;
 // use this for initialization
 void start () {
  destroy(this.gameobject, 4);
  body = this.getcomponent<rigidbody>();
  body.velocity = new vector3(speed, 0, 0);
  player = gameobject.findgameobjectwithtag("bird").transform;
 }
 
 // update is called once per frame
 void update () {
  if (player.transform.position.x > transform.position.x && ispassed == false)
  {
   ispassed = true;
   
   score.instance.getscore();
  }
 }
}

obstacle1.cs

using unityengine;
using system.collections;
 
public class obstacle1 : monobehaviour {
 public float speed = -8f;
 private rigidbody body;
 private transform player;
 private bool ispassed = false;
 // use this for initialization
 void start()
 {
  destroy(this.gameobject, 4);
  body = this.getcomponent<rigidbody>();
  body.velocity = new vector3(speed, 0, 0);
  player = gameobject.findgameobjectwithtag("bird").transform;
 }
 
 
}

此外还有分数显示，最佳分数显示，音效等等，都是细节。
