一、系统设计要求
1.1 课题分析
本游戏系统是利用C#实现， 是制作为我们所熟悉很简单俄罗斯方块游戏,该系统能实现具体功效以下:
1)． 能简便开始游戏,游戏中方块功效和日常我们所熟悉游戏功效一致,多种块设置也一致,包含方块旋转,加速下降,左右移动,满行消去,满行消去自动加分，和到顶游戏结束等功效;
2)． 能够经过对话框窗体说明各个功效使用说明，和部分其它功效。
3)． 界面简练美观,简单易用。跟其它通常游戏相差不大。

1.2 设计环境
本程序选择Visual Studio 作为试验环境。

1.3 设计思绪
用面向对象方法分析系统
对于俄罗斯方块程序制作，我们能够定义一个或多个类，专门来描述俄罗斯方块，在这个类中，包含和之相关方法、属性和字段，经过封装，实现其业务逻辑。其中，每一个俄罗斯方块全部有相同特征，由4个小正方形组成，有旋转，左右移动，下落动作，整行被填满除去并计算分数而组成行小正方体块。基中块形状类型有7种：田、一、L、倒L、Z、倒Z、上。
在窗口中经过调用主窗体Form1当中菜单栏来设置游戏开始、暂停、结束、重新开始和推出程序。还能够经过其菜单中游戏说明选项来查看游戏各个键使用说明，还可调用帮助菜单来查看版权说明。

3.6关键程序代码
1、Form1类
1) 结构函数，设定目前运行方块，下一个立即出现方块，方块产生位置，玩家积分，游戏开关等。
public partial class Form1 : Form
{
private Block currentBlock; //目前在运行方块
private Block nextBlock; //下一个立即出现方块
private Point startLocation = new Point(bianjie.SingleSquareSize * 8, 0); //方块产生位置
private int score = 0; //玩家积分
private bool stillRuning = false; //游戏运行开关
2) 键盘操作：用来选择方块移动方向，是向右移动，向左移动，向下加速，旋转，还是暂停。
/*键盘操作*/
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
switch (e.KeyCode)
{
case Keys.Right: currentBlock.right() ; break;//向右移动
case Keys.Left: currentBlock.left() ; break; //向左移动
case Keys.Up: currentBlock.Rotate(); break; //旋转
case Keys.Down: while (currentBlock.down()) ; break; //向下加速
case Keys.Space: //空格：暂停
timer1.Enabled = !timer1.Enabled;
if (!timer1.Enabled)
showMsg("暂 停");
else msg.SendToBack(); break;
}
picBack.Focus();
}
3） 时钟触发处理函数，使方块自动向下移动，每1秒使方块向下移动一次
/*游戏时钟*/
private void timer1_Tick(object sender, EventArgs e)
{
if (!stillRuning)
return;
//检测是否还能够下移
if (!currentBlock.down())
{
if (currentBlock.Top() == 0)
{//假如到顶则游戏结束
showMsg("Game Over！");
stillRuning = false;
timer1.Stop();
return;
}
//不然计算分数并继续
int eraseLines = bianjie.CheckLines();
if (eraseLines > 0)
{
score += bianjie.width * eraseLines;
t_score.Text = score.ToString();
picBack.Invalidate();
Application.DoEvents();
bianjie.Redraw();
}
//产生下一个block
currentBlock = new Block(startLocation, nextBlock.blockType);
currentBlock.Draw(bianjie.winHandle);
pic_preView.Refresh();
nextBlock = new Block(new Point(50, 50), Block.BlockTypes.undefined);
nextBlock.Draw(pic_preView.Handle);
}
currentBlock.down();
}
4） 对窗口进行重绘
/*窗口重绘*/
private void Form1_Activated(object sender, EventArgs e)
{
picBack.Invalidate();
Application.DoEvents();
bianjie.Redraw();
}
2、SingleBlock类
1) 结构单个方块尺寸，颜色，前景色，背景色
public SingleBlock(Size initSize,Color initForeColor,Color initBackColor)
{
size = initSize;
foreColor = initForeColor;
backColor = initBackColor;
}
2) 画方块，用GDI+绘画，画出填充正方形
//画方块
public void Draw(System.IntPtr winHandle)
{
Graphics g = Graphics.FromHwnd(winHandle);
GraphicsPath gp = new GraphicsPath();
Rectangle rect = new Rectangle(location, size);
gp.AddRectangle(rect);
Color[] surroundColor = new Color[] { backColor };
PathGradientBrush pgb = new PathGradientBrush(gp);
pgb.CenterColor = foreColor;
pgb.SurroundColors = surroundColor;
g.FillPath(pgb, gp);
}
//擦除方块
public void Erase(System.IntPtr winHandle)
{
Graphics g = Graphics.FromHwnd(winHandle);
Rectangle rect = new Rectangle(location,size);
g.FillRectangle(new SolidBrush(bianjie.BackColor),rect);
}
3、Block类
1）随机产生方块形状，并设置四个方块颜色
public Block(Point thisLocation,BlockTypes bType)
{ //当blockType为undefined时，随机产生方块形状
Random rand=new Random();
if (bType == BlockTypes.undefined)
{
blockType = (BlockTypes)(rand.Next(7) + 1);
}
else
blockType = bType;
//设置四小方块颜色
int i=(int)blockType-1;
foreColor = bianjie.BlockForeColor[i];
backColor = bianjie.BlockBackColor[i];
Size SingleSquareS=new Size(SingleSquareSize,SingleSquareSize);
SingleSquare1 = new SingleBlock(SingleSquareS, foreColor, backColor);
SingleSquare2 = new SingleBlock(SingleSquareS, foreColor, backColor);
SingleSquare3 = new SingleBlock(SingleSquareS, foreColor, backColor);
SingleSquare4 = new SingleBlock(SingleSquareS, foreColor, backColor);
2）设置小方块位置，组合成指定形状方块
//设置小方块位置，组合成指定形状一个大方块
switch (blockType)
{
case BlockTypes.SingleSquare:
//组合成正方形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare3.location = new Point(thisLocation.X,thisLocation.Y+SingleSquareSize);
SingleSquare4.location = new Point(thisLocation.X+SingleSquareSize,thisLocation.Y+SingleSquareSize);
break;
case BlockTypes.line:
//组合成线形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare3.location = new Point(thisLocation.X + 2 * SingleSquareSize, thisLocation.Y);
SingleSquare4.location = new Point(thisLocation.X + 3 * SingleSquareSize, thisLocation.Y);
break;
case BlockTypes.J:
//组合成J形
SingleSquare1.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y + SingleSquareSize);
SingleSquare3.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y + 2 * SingleSquareSize);
SingleSquare4.location = new Point(thisLocation.X, thisLocation.Y + 2 * SingleSquareSize);
break;
case BlockTypes.L:
//组合成l形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X, thisLocation.Y + SingleSquareSize);
SingleSquare3.location = new Point(thisLocation.X, thisLocation.Y + 2 * SingleSquareSize);
SingleSquare4.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y + 2 * SingleSquareSize);
break;
case BlockTypes.T:
//组合成T形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare3.location = new Point(thisLocation.X + 2*SingleSquareSize, thisLocation.Y);
SingleSquare4.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y +SingleSquareSize);
break;
case BlockTypes.Z:
//组合成z形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare3.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y + SingleSquareSize);
SingleSquare4.location = new Point(thisLocation.X + 2*SingleSquareSize, thisLocation.Y + SingleSquareSize);
break;
case BlockTypes.S:
//组合成S形
SingleSquare1.location = new Point(thisLocation.X, thisLocation.Y + SingleSquareSize);
SingleSquare2.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y + SingleSquareSize);
SingleSquare3.location = new Point(thisLocation.X + SingleSquareSize, thisLocation.Y);
SingleSquare4.location = new Point(thisLocation.X + 2 * SingleSquareSize, thisLocation.Y);
break;
}
}

/*画方块*/
public void Draw(System.IntPtr winHandle)
{
SingleSquare1.Draw(winHandle);
SingleSquare2.Draw(winHandle);
SingleSquare3.Draw(winHandle);
SingleSquare4.Draw(winHandle);
}
/*擦方块*/
public void Erase(System.IntPtr winHandle)
{
SingleSquare1.Erase(winHandle);
SingleSquare2.Erase(winHandle);
SingleSquare3.Erase(winHandle);
SingleSquare4.Erase(winHandle);
}
3） 移动方块
/*移动*/
public bool down()
{
//检测是否能够下移
if (bianjie.isEmpty(SingleSquare1.location.X / SingleSquareSize, SingleSquare1.location.Y / SingleSquareSize + 1) &&
bianjie.isEmpty(SingleSquare2.location.X / SingleSquareSize, SingleSquare2.location.Y / SingleSquareSize + 1) &&

SingleSquare2.location = new Point(SingleSquare2.location.X, SingleSquare2.location.Y + SingleSquareSize);
SingleSquare3.location = new Point(SingleSquare3.location.X, SingleSquare3.location.Y + SingleSquareSize);
SingleSquare4.location = new Point(SingleSquare4.location.X, SingleSquare4.location.Y + SingleSquareSize);
Draw(bianjie.winHandle);
return true;
}
else //假如不能下移了
{
bianjie.stopSingleSquare(SingleSquare1, SingleSquare1.location.X / SingleSquareSize, SingleSquare1.location.Y / SingleSquareSize);
bianjie.stopSingleSquare(SingleSquare2, SingleSquare2.location.X / SingleSquareSize, SingleSquare2.location.Y / SingleSquareSize);

return false; //表示能够弹出下一个block了
}
}
public bool left()

4） 旋转方块
/*旋转block*/
public void Rotate()
{
//保留每个小块位置
Point oldPosition1 = SingleSquare1.location;
Point oldPosition2 = SingleSquare2.location;
Point oldPosition3 = SingleSquare3.location;
Point oldPosition4 = SingleSquare4.location;
//保留目前方向
RotateDirections oldRotation = myRotation;
//开始试着旋转方块，旋转方向：顺时针方向 旋转中心点为形状拐点
Erase(bianjie.winHandle);
switch(blockType)
