这篇文章主要为大家详细介绍了Unity3d实现Flappy Bird游戏，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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

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。

此外还有分数显示，最佳分数显示，音效等等，都是细节。
