C语言——LCD触摸屏井字棋

使用C语言编写LCD触摸屏井字棋

效果如图

全局变量

int player_counter = 1;//*用于记录落子个数
int data[3][3]={{2,2,2},{2,2,2},{2,2,2}};//*棋盘

井字棋主函数

该函数在工程中为LCD触摸屏触摸的回调函数
LCD像素为240*240

//e->pos.x和 e->pos.y为触摸屏坐标 
int ontouch(int e->pos.x，int e->pos.y)//需要传入触摸坐标
{
    extern void game_char(int flag);

    int over_flag = 2;//*游戏结束标志位，0和1代表不同玩家获胜，2游戏继续进行
    int player;
    player_counter++;//*落子计数器
    player = player_counter % 2;//*玩家判断

游戏复位

用于玩家获胜或平局时重置棋盘

void game_reset(void)//*游戏复位
{
    int i,j;
    player_counter = 1;
    for(i=0;i<3;i++)
        {
        for(j=0;j<3;j++)
        {
            data[i][j] = 2;
        }
    }
}

玩家落子

在LCD屏幕上绘制棋子

void player_draw(int player, int x, int y)//*玩家落子
{
    extern int lcd_draw_fork(int x,int y,int r,u16 color);
    extern int lcd_draw_circular(int x,int y,int r,u16 color);
    if(player == 1)
    {
        lcd_draw_fork(x,y,25,0x9999);//*触摸点画叉
    }
    else if(player == 0)
    {
       lcd_draw_circular(x,y,25,0x6666);//*触摸点画圆
    }
}

胜负判断

根据落子坐标判断胜负，返回0和1代表不同玩家获胜，2无人获胜

int game_referee(int player,int x,int y)
{
    int xay = x+y;
    if(data[x][0]==player && data[x][1]==player && data[x][2]==player)//*所在行检测
    {
        return player;
    }
    else if(data[0][y]==player && data[1][y]==player && data[2][y]==player)//*所在列检测
    {
        return player;
    }
    else if(xay!=3 || xay!=5)//*斜检测
    {
        if(data[0][0]==player && data[1][1]==player && data[2][2]==player)
            {
                return player;
            }
        else if(data[0][2]==player && data[1][1]==player && data[2][0]==player)
            {
                return player;
            }
    }
    return 2;
