1、西安科技大学计算机学院VC+程序设计实验报告题 目 俄罗斯方块游戏 学 号 0808030405 专业及班级 计算机科学与技术专业0804班姓 名 日 期 2010/11/25 一、 实验目的本实验的目的是综合前面所学的知识,参考实验指导书的知识，开发一个俄罗斯游戏。二、 设计思路1 游戏说明及规则Tetris游戏在一个m*n的矩形框内进行。游戏开始时，矩形框的顶部会随机出现一个由四个小方块构成的砖块，每过一个很短时间（我们称这个时间为一个tick）,它就会下落一格，直到它碰到矩形框的低部，然后再过一个tick它就会固定在矩形框的底部，成为固定块。接着再过一个tick顶部又会现一个随机形状，同
2、样每隔一个 tick都会下落，直到接触到底部或者接触到下面的固定块时，再过一个tick它也会成为固定块，再过一个tick之后会进行检查，发现有充满方块的行则会消除它，同时顶部出现下一个随机形状。直到顶部出现的随机形状在刚出现时就与固定块重叠，表示游戏结束。操作说明：光标左键左移 光标右键右移 光标上键翻转 光标下键下移2 Tetris的游戏分析，设计与实现(1)Tetris游戏的矩形框类CBin 首先我们应该描述 Tetris游戏的矩形框。这里我们定义一个CBin类描述Tetris游戏的矩形框。对矩形框进行分析，它应该有三个私有的数据成员为：image,width和height.Cbin类将T
3、etris游戏的矩形框描述成为一个二维数组image,变量width和height存储了image的维数。接下来为CBin类添加五个成员函数：构造函数：CBin(unsigned int w,unsigned int h)，析构函数：Cbin()， void getImage(unsigned char*destImage), void setImage(unsigned char*srcImage),unsigned int removeFullIines(). 然后分别在bin.h和bin.cpp中完成Cbin类的定义和函数实现。 (2)Tetris游戏的砖块类:第一步:建立类:CIBri
4、ck, CLBrick, CSBrick，CTBrick, CFSBrick，CFLBrick, COBrick，它们的基类都是CBrick类。它们都有有四个数据成员:orientation,posX,posy,colour. Orientation表示”1”砖块的四个状态,可能取值为0,1,2,3,由状态0到状态1是”1”砖块固定一个特定点顺时针旋转90度.依次类推,状态3的下一个状态是状态0. posX,posy记录了特定点的坐标, colour为砖块的颜色值. 为CIBrick重载7个虚构函数:int shifLeft(CBin*bin), int shifRight(CBin*bin)
5、,int shifDown(CBin*bin), int rotateClockwise(CBin*bin), int checkCollision (CBin*bin),void operator(unsigned char*binImage),void putAtTop(unsigned int newOrient,unsigned int new PosX).第二步:仿照CIBrick,完成CLBrick, CSBrick，CTBrick, CFSBrick，CFLBrick, COBrick类的实现,同样将类定义代码写在brick.h文件中,类实现代码写在brick.h文件中.3. 进
6、一步完善（1）实现砖块的三维化在试图类定义（NewTetrisView .h）中添加两个公有的成员函数声明。在视图类的实现文件（NewTetrisView .cpp）中，添加这两个函数的实现代码。修改试图类的DrawImage函数，添加代码。（2） 使用双缓冲技术解决屏幕闪烁 修改视图类的OnDraw函数。修改视图类的DrawImage函数。4背景音乐的实现。三、 代码实现（代码省略部分参照实验指导书）1. 然后分别在bin.h和bin.cpp中完成Cbin类的定义和函数实现：在文件bin.h中添加三个成员变量和六个成员函数并初始化（代码省略） unsigned char*imgage; un

9、etColour()return colour;void setOrientation(unsigned int newOrient)orientation=newOrient;void setPosX(unsigned int newPosX)posX=newPosX; void setPosY(unsigned int newPosY)posY=newPosY;void setColour(unsigned char newColour)colour=newColour;virtual int shiftLeft(CBin* bin)=0; virtual int shiftRight(C

11、Brick:public CBrickpublic:int shiftLeft(CBin*bin);int shiftRight(CBin*bin);int shiftDown(CBin*bin);int rotateClockwise(CBin*bin);int checkCollision(CBin*bin);void operator(unsigned char*binImage);void putAtTop(unsigned int newOrient,unsigned int newPosX);在后面实现CLBrick, CSBrick，CTBrick, CFSBrick，CFLBr
