Unity中利用C#开发泡泡龙游戏

泡泡龙是一款非常经典的游戏，版本有很多，如百度的《彩色泡泡》等。游戏开始时，泡泡应该出现m行；如果连续n次发射泡泡没有出现同色泡泡相消的情况，在屏幕上方自动加上一行泡泡；如果屏幕中泡泡全部被同色相消掉，则过关；如果屏幕中泡泡行数达到max行，则认为闯关失败。

开发软件: Unity

开发语言: C#

对一些数据的定义及封装：

<pre class="csharp" name="code">public  const int MaxRow = 11;     //泡泡所在位置的最大行public  const int MaxColumn = 9;   //泡泡所在位置的最大列public  int RowNum=8;     //初始化时产生气泡 行数public  int ColumnNum = 9;//初始化时产生气泡 列数public GameObject[] BubblePrefab; //预制对象数组public  struct BubbleClass        //bubble 结构体{public GameObject BubbleObj; //实例化的对象public int type;             //泡泡类型   如果颜色不同，则也认为类型不同public Vector3 position;     // 泡泡位置public bool  IsDestroy;      //当前位置的泡泡是否被销毁    如果当前位置的泡泡被销毁，则认为当前位置空闲，可以容纳发射的泡泡public int   Life;           //不同类型的泡泡生命值不同 public bool  Isconnection; //true表示与第一排相连   false表示不与第一排小泡相连}public  BubbleClass[,] BubbleArray;        //屏幕中MaxRow*MaxColumn格中泡泡数组public  BubbleClass    BubbleCurrentShoot; //当前要发射的泡泡public  BubbleClass    BubbleNextShoot;    //下一次要发射的泡泡public  float          BubbleMoveSpeed=5f; //小球移动速度public  float          CircleRadius=0.24f;//小泡半径private int NextNum=-1;    //发射球下一次标号     private int CurrentNum=-1; //发射球当前标号     private Vector3 NextPoint=new Vector3(-1.4f,-3.8f,0f); //下一个小泡发射位置 new Vector3(1.2f,-3.7f,0f)private Vector3 StartPoint=new Vector3(0.026f,-3.65f,0f); //小泡发射起点位置 new Vector3(0f,-3.6f,0f)public enum BState{READY,FLY,FINISH};//待发射小泡的三种状态 发射前（准备态）,运动中, 完成态public BState BubbleState;//private int BubblePrefabLength=0;public bool BubbleInitFlag=false;public float HorizontalStartX = -3.0f;       //开始点X -1.75public float VerticalStartY=3.0f;             //开始点Ypublic float HorizontalDistance=0.5f;         //水平小泡之间间距public float VerticalDistance=0.45f;          //竖直小泡之间间距public float HorizontalIdentitationDis=0.25f; //水平右缩进距离public bool IdentitationFlag=false; //true代表 0,2,4,6,8,10为缩进，1,3,5,7,9为不缩进  false则相反public int CurrentRowCount=0; //当前屏幕中气泡行数//设计共10关 public  int GameLevel=1;         //游戏难度等级   public int BubbleKindsCount=4; //当前等级下的小泡种类private GameObject[] BubbleCurrentPrefab; //当前难度等级下的小泡预制对象数组public bool StartFlag=false; //开始标志public GameObject Menu; //菜单对象public int ShootBubbleCount=0; //发射小泡数public int Score=0;public UILabel LabelPoint;public int BubbleScore=10; //打掉一个气泡的得分public int BubbleBoudary=0;//连续几次没打中，则加一排小泡

 

涉及的主要步骤有：

(1)泡泡的产生。

初始屏幕泡泡的产生，相邻两行泡泡需要交错，才能形成完整的正六边形。主要代码：

//随机在屏幕上方方格产生气泡  初始化时调用此函数public void InitProduceScreenBubble(){int flagBubble = -1;for(int i=0;i<RowNum;i++){if(i==0){ flagBubble=Random.Range(0,2);//产生0,1数  0为这排气泡最左边气泡抵墙，1为此排气泡整体右缩进}else{if(flagBubble==0){flagBubble=1;}else{flagBubble=0;}}for(int j=0;j<ColumnNum;j++){float x1;if(i==0)   //第一排小泡{if(flagBubble==0){x1=HorizontalStartX+HorizontalDistance*j;IdentitationFlag=false;}else{x1=HorizontalStartX+HorizontalDistance*j+HorizontalIdentitationDis;IdentitationFlag=true;}}else  //其它排小泡{if(flagBubble==0){x1=HorizontalStartX+HorizontalDistance*j;}else {x1=HorizontalStartX+HorizontalDistance*j+HorizontalIdentitationDis;}}int temp=Random.Range(0,BubbleKindsCount); //为类型标号float x2=VerticalStartY-VerticalDistance*i;Vector3 tposition= new Vector3(x1,x2,0f);GameObject obj2=GameObject.Instantiate(BubblePrefab[temp],tposition,Quaternion.identity) as GameObject;BubbleArray[i,j].BubbleObj=obj2;BubbleArray[i,j].IsDestroy=false;BubbleArray[i,j].Life=1;BubbleArray[i,j].position=tposition;BubbleArray[i,j].type=temp;BubbleArray[i,j].Isconnection=true;}}}

发射小泡的产生：

//随机在下方产生当前和下一次要发射的小泡public void ProduceBubbleBottom(){if((CurrentNum==-1)&&(NextNum==-1))  //说明游戏刚开始{int m1 = Random.Range (0, BubbleKindsCount);int m2 = Random.Range (0, BubbleKindsCount);CurrentNum=m1;NextNum=m2;GameObject obj1=GameObject.Instantiate(BubblePrefab[m1],StartPoint,Quaternion.identity) as GameObject;GameObject obj2=GameObject.Instantiate(BubblePrefab[m2],NextPoint,Quaternion.identity) as GameObject;InitBubbleCurrent(obj1,m1,StartPoint,false,1);InitBubbleNext(obj2,m2,NextPoint,false,1);BubbleState=BState.READY;}else //如果游戏进行中{CurrentNum=NextNum;BubbleCurrentShoot.BubbleObj=BubbleNextShoot.BubbleObj;BubbleCurrentShoot.IsDestroy=BubbleNextShoot.IsDestroy;BubbleCurrentShoot.Life=BubbleNextShoot.Life;BubbleCurrentShoot.type=BubbleNextShoot.type;BubbleCurrentShoot.BubbleObj.transform.position=StartPoint;BubbleCurrentShoot.position=StartPoint;int m2 = Random.Range (0, BubbleKindsCount);GameObject obj2=GameObject.Instantiate(BubblePrefab[m2],NextPoint,Quaternion.identity) as GameObject;InitBubbleNext(obj2,m2,NextPoint,false,1);NextNum=m2;BubbleState=BState.READY;}}

发射小泡的运动：将发射小泡添加Rigidbody属性，去掉重力，设置其速度Velocity（矢量）即可实现运动。

//气泡发射函数void BubbleShoot(){//如果鼠标左击if(Input.GetMouseButton(0)){//UICamera.mainCamera.ScreenToWorldPointVector3 currentPosition = BubbleCurrentShoot.position ;Vector3 moveToward = Camera.main.ScreenToWorldPoint( Input.mousePosition );Vector3 moveDirection = moveToward - currentPosition;moveDirection.z = 0; moveDirection=moveDirection.normalized;Vector2 Direction=new Vector2(moveDirection.x,moveDirection.y);BubbleCurrentShoot.BubbleObj.rigidbody2D.velocity=Direction.normalized*BubbleMoveSpeed;//BubbleState==BState.FLY;  //小泡发射后就变为运动态BubbleState=BState.FLY;}}

（2) 发射小泡的碰撞检测

a. 发射小泡碰撞到左右屏幕边界，则需要反向弹回。

发射小泡从AO射入，则从OB射出，且OB与X同OA与X的夹角是相同的。检测方法，则在屏幕左右边缘加上“线碰撞器”，当发射小泡碰撞线碰撞器时，进入碰撞函数，改变发射小泡的速度方向即可。

void OnTriggerEnter2D(Collider2D collision){//屏幕边界碰撞检测if(maincontrol.BubbleInitFlag){if(collision.gameObject==maincontrol.BubbleCurrentShoot.BubbleObj){Vector2 tp = collision.gameObject.rigidbody2D.velocity;tp=new Vector2(-tp.x,tp.y);collision.gameObject.rigidbody2D.velocity= tp.normalized*maincontrol.BubbleMoveSpeed;}}}

 

b.发射小泡与屏幕中小泡碰撞

屏幕中的小泡以及发射小泡都是预制(Prefab）对象实例化而得到的。因而在的=建立预制对象时，就给预制对象加上组件”Circle Collider 2D"，圆形2D碰撞器，为了去掉物理特性碰撞，选择“IsTrigger" ，这是为了避免小泡被撞飞。 注意： Unity 中要实现碰撞，务必保证碰撞物体和被撞物体两者中至少有一个具有刚体属性。

//小泡碰撞检测函数void OnTriggerEnter2D(Collider2D collision){if(maincontrol.StartFlag==true){//如果当前气泡就是发射气泡if(maincontrol.BubbleInitFlag){if(collision.gameObject==maincontrol.BubbleCurrentShoot.BubbleObj){maincontrol.ShootBubbleCount++;Vector2 tp = collision.gameObject.rigidbody2D.velocity;collision.gameObject.rigidbody2D.velocity= tp.normalized*0f;//调整发射小泡的位置ShootBubblePosition(gameObject);//Debug.Log ("行号:" + bbPosition.rown+"列号:" + bbPosition.columnn);Count=0;InitBubbleSameType();//delete []BubbleSameType;BubbleSameType[Count].obj=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].BubbleObj;BubbleSameType[Count].rowNum=bbPosition.rown;BubbleSameType[Count].ColumnNum=bbPosition.columnn;Count++;CountBubble(maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].BubbleObj,maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].type);if(Count>=3){maincontrol.ShootBubbleCount=0;int r=FindMinRow(); //找出颜色相同气泡中最小行号for(int i=0;i<Count;i++){GameObject CrackObj=GameObject.Instantiate(BubbleCrackPrefab,BubbleSameType[i].obj.transform.position,Quaternion.identity) as GameObject;Destroy(CrackObj,1f);Destroy(BubbleSameType[i].obj);int k1=BubbleSameType[i].rowNum;int k2=BubbleSameType[i].ColumnNum;maincontrol.BubbleArray[k1,k2].BubbleObj=null;maincontrol.BubbleArray[k1,k2].IsDestroy=true;maincontrol.BubbleArray[k1,k2].Life=0;maincontrol.BubbleArray[k1,k2].type=-1;maincontrol.BubbleArray[k1,k2].Isconnection=false;}//Debug.Log(Count);maincontrol.Score+=Count*maincontrol.BubbleScore;   Count=0;InitBubbleSameType();QueryBubbleSuspended(r);//清除悬空气泡if(Count>=1){for(int i=0;i<Count;i++){Destroy(BubbleSameType[i].obj);int k1=BubbleSameType[i].rowNum;int k2=BubbleSameType[i].ColumnNum;maincontrol.BubbleArray[k1,k2].BubbleObj=null;maincontrol.BubbleArray[k1,k2].IsDestroy=true;maincontrol.BubbleArray[k1,k2].Life=0;maincontrol.BubbleArray[k1,k2].type=-1;maincontrol.BubbleArray[k1,k2].Isconnection=false;}//Debug.Log(Count);}   maincontrol.Score+=Count*maincontrol.BubbleScore;   } else{//连续3次没打中想销毁if(maincontrol.ShootBubbleCount==maincontrol.BubbleBoudary){Vector3 pp=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].position;pp.y=tp.y-maincontrol.VerticalDistance;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].BubbleObj=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].BubbleObj;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].BubbleObj.transform.position=pp; maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].position=pp;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].IsDestroy=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].IsDestroy;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].Life=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].Life;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].type=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].type;maincontrol.BubbleArray[bbPosition.rown+1,bbPosition.columnn].Isconnection=maincontrol.BubbleArray[bbPosition.rown,bbPosition.columnn].Isconnection;}}Count=0;InitBubbleSameType();maincontrol.BubbleCurrentShoot.BubbleObj=null;maincontrol.BubbleCurrentShoot.IsDestroy=true;maincontrol.BubbleCurrentShoot.position=new Vector3(0f,0f,0f);maincontrol.BubbleCurrentShoot.type=-1;maincontrol.BubbleState=MainControl.BState.FINISH;maincontrol.BubbleCurrentShoot.Isconnection=false;}  }}}

 

（3）发射泡泡运动停止后的位置确定

下图绿色为被撞泡泡，以其为中心的六边形如下：图片来源：http://blog.csdn.net/luchenqun/article/details/8393879

根据碰撞函数可以得到被碰小泡（上面绿色）的坐标，根据它，可以得出其周围六个顶点小泡的位置 （假设都有小泡），再根据 

public  BubbleClass[,] BubbleArray;

数组（记录了屏幕中所有泡泡信息），判断六个位置是否有泡泡，根据发射小泡入射角度和六边形角度范围，给出发射小泡的位置。

//计算当前被撞小泡的位置  即当前小泡对象  obj为发射小泡碰撞的小泡void ShootBubblePosition(GameObject obj){int row=0, column=0;bool isIdentitation=false;GeneralBubblePosition (ref row, ref column,obj.transform.position); //if(maincontrol.IdentitationFlag){if(row%2==0){isIdentitation=true;}else{isIdentitation=false;}}else{if(row%2==0){isIdentitation=false;}else{isIdentitation=true;}}//int Currenttype=maincontrol.BubbleArray[row,column].type;bool Ichange = false; //判断obj小泡周围是否有同颜色的小泡（重复的不算）//float pbegin,pbegin1;//float pend,pend1;int LeftUpNum, LeftDownNum, RightUpNum, RightDownNum;Vector3 tp = maincontrol.BubbleCurrentShoot.BubbleObj.transform.position -

（5）泡泡掉落（主要判断泡泡是否直接或间接与屏幕中第一行的泡泡相连）

如果没有相连（即泡泡悬空），泡泡会自然掉落（也需要消去）。
