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 initializationvoid 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 framevoid 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 initializationvoid 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 initializationvoid 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 framevoid 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，这里上完整实现的文件下载。

（3D模型是同学做的，音效是原版小鸟里找的)
