俄罗斯方块游戏
一、 实验目的
基于博创UP-NETARM300试验台，开发一个简单的俄罗斯方块游戏，并达到以下要求：
（1）按Numlock键重新开始游戏，随机产生方块并自动下落；
（2）按“/”键可以暂停游戏，再次按键开始游戏；
（3）用“8”键变换方块角度，用“7”实现左移，用“9”实现右移，用“5”实现方 块加速下移；
（4）系统能够正确判断是否满行，并对已满的行实现消行并加分。
二、实验设备
计算机；博创UP-3000实验箱

功能模块划分
3、1绘图API数据结构
在uC/OS-II系统环境下，绘图必须通过使用绘图设备上下文（DC）来实现。绘图设备上下文（DC）中包括了与绘图相关的信息，比如画笔宽度、绘图的原点等。这样在多任务的系统中，不同的任务通过不同的绘图设备上下文（DC）绘图才不会相互影响。绘图设备上下文（DC）的结构定义如下：
typedef struct{
int DrawPointx;
int DrawPointy; //绘图所使用的坐标点
int PenWidth; //画笔宽度
U32 PenMode; //画笔模式
- 2 -
COLORREF PenColor; //画笔的颜色
int DrawOrgx; //绘图的坐标原点位置
int DrawOrgy;
int WndOrgx; //绘图的窗口坐标位置
int WndOrgy;
int DrawRangex; //绘图的区域范围
int DrawRangey;
structRECT DrawRect;//绘图的有效范围
U8 bUpdataBuffer; //是否更新后台缓冲区及显示
U32 Fontcolor; //字符颜色
}DC,*PDC;
与绘图上下文（DC）有关的函数：initOSDClassic();用来初始化系统的DC，为DC开辟动态内存空间：Create（）和DestoryDC（）分别用来创建和删除DC。
和绘图有关的函数有TextOut（）、LIneTo（）、FillRect（）等。
在uC/OS-II系统中，液晶显示屏的刷新时通过Lcd_Fresh_Task()任务完成的，该任务在系统附加任务初始化函数OSADDTask_Init()中定义的，该函数开辟了LCD刷新任务、触摸屏任务、键盘任务等。
3、2消息循环
通常在多任务操作系统中，人物之间的通讯是通过发送消息来实现的。消息队列是操作系统uC/OS-II中的一种通讯机制，uC/OS-II操作系统提供了若干对消息队列进行操作的函数，例如OSQCreate（）、OSQPend（）、OSQPost（）等，他们都定义在OS_Q.c中。在本开发平台中程序可以使用OSCreateMessage（）创建消息，用SendMessage（）发送消息等。
消息的数据结构定义：
typedef struct {
POS_Ctrl pOSCtrl; //消息所发到的窗口(控件)
U32 Message;
U32 WParam; //键盘消息参数
U32 LParam; //触摸屏消息参数
}OSMSG, *POSMSG;
对于键盘消息来说其类型pMsg->Message=OSM_KEY，参数pMsg->WParam是按键的键码，键盘中断服务程序向键盘邮箱发送一个消息，通知键盘扫描任务发生了按键事件。当按键扫描任务等到邮箱消息后就会从键盘扫描芯片读取扫描吗，然后将扫描码对应的按键码发送到消息队列。
3、3方法处理
（1）规划屏幕，规划出一个20行10列的游戏区域，每个小方块用10X10的像素来构成。
int BoardArray[10][20]; //定义一个10x20的游戏区域
（2）标准的俄罗斯方块共有7种形状，每个形状划分为4种角度且有四个小方块组成，每个小方块的坐标由（x,y）确定，所以数组定义如下：
int BlockInfo[7][4][4][2]=
{
{
{{0,0},{1,0},{0,1},{1,1}},
- 3 -
{{0,0},{1,0},{0,1},{1,1}},
{{0,0},{1,0},{0,1},{1,1}},
{{0,0},{1,0},{0,1},{1,1}}
},
{
{{0,0},{-1,0},{1,0},{2,0}},
{{0,0},{0,-1},{0,1},{0,2}},
{{0,0},{-1,0},{1,0},{2,0}},
{{0,0},{0,-1},{0,1},{0,2}}
}
};
这里只给出正方形的和长方形的，具体见附录。

3、4程序任务处理流程
1）主任务，它主要来完成一些初始化工作，要初始化游戏界面，必须创建一个绘图用的DC，主任务通过DC绘制游戏界面调用API函数显示相应的文字。初始化工作完成后，主任务进入消息循环机制来等待来自键盘或触摸屏的消息，获得消息后发送到消息处理机制中。主任务创建方式及流程图如下：
创建方式：
void Main_Task(void*Id);
#define Main_Task_Prio 12
OSTaskCreate(Main_Task,(void*)0,(OS_STK*)&Main_Stack[STACKSIZE*8-1],
Main_Task_Prio);
- 4 -
流程图：
俄罗斯方块主任务流程图
2)方块自动下落任务，主要完成当前方块的动态显示，不停的更新方块的位置，另外还要判
断系统的运行状态，方块是否发生碰撞等。自由下落任务的创建方式与流程图如下：
创建方式：
void AutoDrop_Task(void*Id);
#define AutoDrop_Task_Prio 20
OSTaskCreate(AutoDrop_Task,(void*)0,(OS_STK*)&AutoDrop_Task_Stack[STACKSIZE
-1],AutoDrop_Task_Prio);
- 5 -

3）键盘消息捕捉任务
void onKey(int nkey,int fnkey) {
switch(nkey)
{
case 0:
newGame();
return;
case 1:
pause();
return;
case 4:
moveLeft();
return;
case 6:
moveRight();
return;
case 9:
drop();
return;
case 5:
rotateClockwise();
- 6 -
return;
default:
return;
}
}
当键盘获取消息时，根据键盘值选择接下来要进行的操作。
