开发进度

1.初步完成地图类Board。

Board::Board{
    //初始化块，时间间隔，分数
   	score_player1=0;
	score_player2=0;
    block = new Block(this);
    time = 200;
    height=22;
    width=10;
    //初始化地图
    for(int i=0; i<=height+1; i++)
        for(int j=0; j<=width+1; j++)
            map[i][j] = '#';//外围多一圈，便于消行时操作执行 
}
void Board::confirm(Player player){
    //将块更新到map
    if(player.num==1){
    	char (&map_1)[50][50]=map_player1;
    	char (&map_2)[50][50]=map_player2;
	}
	else{
    	char (&map_1)[50][50]=map_player2;
    	char (&map_2)[50][50]=map_player1;		
	}//给map取别名    		
    for(int i=0; i<4; i++)
        for(int j=0; j<4; j++){
            int tx = block->x + i;
            int ty = block->y + j;
            if(tx<1 || tx > height || ty < 1 || ty > width)
                continue;
            if(block->BLOCKS[block->type][i][j] != '#')
                map_1[tx][ty] = block->BLOCKS[block->type][i][j];
        }
    //消去完整的行并计算行个数
    int cnt = 0;
    for(int i=height; i>=1; i--)
    {
        bool flag = false;
        for(int j=1; j<=width; j++)
            if(map_1[i][j] == '#')
            {
                flag = true;
                break;
            }
        if(flag)
            continue;
        cnt++;
        for(int j=i; j>=1; j--)
            for(int k=1; k<=width; k++)
                map_1[j][k] = map_1[j-1][k];//消行用上一行取代下一行 
    }
    //计分 
    if(cnt)
        player.score += 10*(cnt);
    //每下落一个块，时间间隔减2
    time -= 2;
    if(time < 0)
        time = 0;
    //更新块
    block->toNext();
    for(int j=1; j<=height; j++)
        for(int k=1; k<=width; k++)
            map_2[j][k] = map_2[j+1][k];//此消彼长用下一行取代上一行	 
}
bool Board::isEnd(){
    for(int i=1; i<=width; i++)
        if(map[1][i] != '#')
            return true;
    return false;
}

2.方块类Block的部分成员函数。

bool Block::detect(int flag){
    //获得当前操作的目标状态：目标坐标，目标方块类型。
    int nextX, nextY, nextType;
    // 0,1,2,3对应上下左右
    switch(flag)
    {
        case 0: nextX = x; nextY = y; nextType = NEXT[type]; break;
        case 1: nextX = x+1; nextY = y; nextType = type; break;
        case 2: nextX = x; nextY = y-1; nextType = type; break;
        case 3: nextX = x; nextY = y+1; nextType = type; break;
    }

    for(int i=0; i<4; i++)
        for(int j=0; j<4; j++)
        {
            //tx，ty表示i，j所对应的地图的实际位置。
            int tx = nextX+i;
            int ty = nextY+j;
            //边界处理
            if(tx < 0 || tx > board->height+1 || ty < 0 || ty > board->width+1)
                continue;
            //如果块与地图墙相重合，则发生碰撞
            if(BLOCKS[nextType][i][j] != '#' && (ty == 0 || ty == board->width+1))
                return false;
            if(BLOCKS[nextType][i][j] != '#' && board->map[tx][ty] != '#')
                return false;
        }
    return true; 
}
Block::Block(Board *board){
	this->board = board;
    x = -3;
    y = 4;
    //随机数确定第一个块的类型
    srand((unsigned) time(NULL));
    type = rand()%19;
    nextType = rand()%19;
    //读入方块类型
    freopen("block.bin", "rb", stdin);
    for(int i=0; i<19; i++)
    {
        for(int j=0; j<4; j++)
            cin>>BLOCKS[i][j];
    }
    //next数组模拟指向，用于方块旋转功能
    for(int i=0; i<3; i++){
        for(int j=0; j<3; j++)
            NEXT[i*4+j] = i*4+j+1;
        NEXT[i*4+3] = i*4;
    }
    for(int i=12; i<18; i+=2){
        NEXT[i] = i+1;
        NEXT[i+1] = i;
    }
    NEXT[18] = 18;
    //设置每种方块对应的颜色
    COLOR[1] = Qt::blue;
    COLOR[2] = Qt::darkBlue;
    COLOR[3] = Qt::yellow;
    COLOR[4] = Qt::magenta;
    COLOR[5] = Qt::darkMagenta;
    COLOR[6] = Qt::cyan;
    COLOR[7] = Qt::red;
}

3.完成了游戏主界面的渲染。

采用windows进行渲染，目前已经实现了游戏所需求的基础页面，剩下键盘输入实现接下来的功能，所实现代码以及可执行文件已发送至仓库，实现的界面如图

出现的问题

1.各个类的代码未经测试
2.三人分工写代码，各个类之中有矛盾的地方，需要讨论细化
