這篇文章主要為大家詳細介紹了Unity3d實現(xiàn)Flappy Bird游戲，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Unity3d實現(xiàn)Flappy Bird的具體代碼，供大家參考，具體內(nèi)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(diào)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(zhí)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(chǎn)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(nèi)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(shù)顯示，最佳分數(shù)顯示，音效等等，都是細節(jié)。
