本文實例為大家分享了Unity3d實現Flappy Bird的具體代碼，供大家參考，具體內容如下

一、小鳥

在游戲中，小鳥并不做水平位移，而是通過障礙物的移動讓小鳥有水平運動的感覺，小鳥只需要對鼠標的點擊調整豎直加速度就可以了，同時加上水平旋轉模仿原版的FlappyBird的運動。同時，還要對豎直位置進行判斷，否則游戲不能正常結束。

這里貼上小鳥上附加的腳本代碼

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; //確保只執行一次 private int bestScore = 0;  // Use this for initialization void Start () {    body = transform.GetComponent<Rigidbody>();   }  void OnCollisionEnter(Collision collisionInfo) {  if (state)  {   //碰撞游戲結束   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);   }  }  //判斷鼠標左鍵點擊或者空格  if (Input.GetKeyDown(KeyCode.Space)||Input.GetMouseButtonDown(0))  {   AudioManager.instance.PlayFly();   body.velocity = Vector3.zero;   //加速度   body.AddForce(jumpForce);   //控制旋轉量   this.transform.rotation = Quaternion.Euler(45, 270, 0);  }     else  {    //旋轉   if (transform.rotation.eulerAngles.x >= 280||transform.rotation.eulerAngles.x<=50)   {        transform.Rotate(-150 * Time.deltaTime, 0, 0);   }  }  }  public void EndGame() {  //保存最佳成績  PlayerPrefs.SetInt("PlayerScore", Score.instance.score);  bestScore = PlayerPrefs.GetInt("PlayerBestScore");  if (Score.instance.score > bestScore)   bestScore = Score.instance.score;  PlayerPrefs.SetInt("PlayerBestScore", bestScore);  //跳轉到結束場景  Application.LoadLevel("End"); } }

二、障礙物

障礙物只要定時產生，隨機設定偏移量，然后添加向左運動的速度就行了，同時要設定自動銷毀的時間，回收障礙物，否則內存占用會越來越大。

這里用了三個腳本，分別是上下障礙物和障礙物生成腳本。附加到一個空物體上就行了。

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; }  }

此外還有分數顯示，最佳分數顯示，音效等等，都是細節。
