c++ - 在 C++ 中检测与数组的冲突

Question

所以我打印了一个二维 map 数组。我将 0 设置为空格，将 1 设置为墙。我有陷阱和健康以及玩家等变量。但是，当两者发生冲突时，我无法实现得分。我想知道我如何检测玩家和生命何时发生碰撞，这会使健康变量增加 1。现在每次我移动它都会增加。谢谢你!这些是我的变量函数

void putplayer()
{
    setcolor(9);
    gotoxy( player.x +mazex,    player.y  +mazey); 
    cout<<playersymbol;
    setcolor(7);

}

void puttreasure()
{
    setcolor(14);
    gotoxy(treasure.x +mazex, treasure.y +mazey);
    cout<<treasuresymbol;
    setcolor(7);

}

void puttraps()
{
    setcolor(14);
    gotoxy( traps.x +mazex,    traps.y  +mazey); 
    cout<<trapssymbol;
    setcolor(7);

}

void putlives()
{
    setcolor(14);
    gotoxy( lives.x +mazex,    lives.y  +mazey); 
    cout<<livessymbol;
    setcolor(7);

}

void moveleft()
{
    gotoxy(31,7);
    cout<<"left key   move player left    \n\n";
     if (maze[player.y][player.x-1]==0)   player.x = player.x -1;
}

然后是我的 Main，但是我删除了一些代码，因为它可能不相关

int main()
{
    DWORD        mode;          /* Preserved console mode */
    INPUT_RECORD event;         /* Input event */
    BOOL         EXITGAME = FALSE;  /* Program termination flag */
  //  unsigned int counter = 0;   /* The number of times 'Esc' is pressed */


    /* Get the console input handle */
    HANDLE hstdin = GetStdHandle( STD_INPUT_HANDLE );

    /* Preserve the original console mode */
    GetConsoleMode( hstdin, &mode );

    /* Set to no line-buffering, no echo, no special-key-processing */
    SetConsoleMode( hstdin, 0 );

   srand ( time(NULL) ); //initialize the random seed

    // Variables
    int health = 0;

   // Declare variable positions
    player.x=1;
    player.y=1;
    treasure.x = 1;
    treasure.y = 3;
    traps.x =  1;
    traps.y = 7;
    lives.x = 1;
    lives.y = 9;

    clrscr();
    setcolor(15);


    while (!EXITGAME)
    {
        if (WaitForSingleObject( hstdin, 0 ) == WAIT_OBJECT_0)  /* if kbhit */
        {
            DWORD count;  /* ignored */

            /* Get the input event */
            ReadConsoleInput( hstdin, &event, 1, &count );

            /* Only respond to key release events */
            if ((event.EventType == KEY_EVENT)
            &&  !event.Event.KeyEvent.bKeyDown)

            clrscr();
            putmenu();
            gotoxy(6,20);
            cout<<"Lives: " << health;
            Sleep(100);


                switch (event.Event.KeyEvent.wVirtualKeyCode)
                {
                    case VK_ESCAPE:
                       EXITGAME = TRUE;
                     break;

                    case VK_LEFT:
                        // left key   move player left
                         moveleft();
                     break;

                    case VK_RIGHT:
                        // right key   move player right
                        moveright();

                     break;

Answer 1

你有密码

if(maze[player.x][player.y] = maze[lives.x][lives.y])

将 maze[player.x][player.y] 设置为 maze[lives.x][lives.y] 的值，然后对其求值(如果为 1(墙)，则求值为 true，为 false如果为 0(空格))。我想你是想拥有类似的东西

if((player.x == lives.x) && (player.y == lives.y))

这将(据我所知)评估玩家和生命是否在同一位置。
