這是瓷磚類

我不知道如何基本復位電路板時，即時通訊改變的難度，或者當我計劃設置自定義板選項如何根據給定的磁貼數量自動調整電路板大小。

如果你不能告訴...我很新的代碼。謝謝您的幫助。

這不是已經做到了大部分？

if (menu.equals("Easy")) 
    { 
     setSize(500,600); 
     makeBoard(9,9); 
     // TODO need to reset the board 
    } 
    if (menu.equals("Medium")) 
    { 
     setSize(850,950); 
     //TODO figure out how to change the flag counter... 
     makeBoard(16, 16); 
    } 
    if (menu.equals("Hard")) 
    { 
     setSize(1550,950); 
     makeBoard(30,16); 
    } 

有人從菜單中選擇一個選項會觸發事件。事件處理程序包含一個if/else塊，可以：退出，設置爲簡單，設置爲中等，設置爲硬。 makeBoard函數處理灰色瓷磚的實際顯示，據我所知，對於所有瓷磚，佔用設置爲'g'（灰色？）。如果你問的是實際生成的炸彈等，我沒有看到有關這方面的任何內容。它要麼照顧你，你沒有提供代碼，或者你必須自己寫。

您需要將int easyFlags設置爲它們爲特定難度獲得的許多值。 您需要將flagCounter標籤設置爲0. 您需要設置timecounter標籤t0 0. 您需要將int礦設置爲儘可能多的難度。

的menu.equals（「易」），如果塊將是這樣的：

if (menu.equals("Easy")) 
    { 
     setSize(500,600); 
     makeBoard(9,9); 
     flagCounter.setText("0"); 
     timecounter.setText("0"); //or "0:00" or w/e 
     mines = 10; 
     easyFlags = 10; 
    } 

有可能略多，但我不想做的顯然是某種形式的學校項目，爲您大聲笑
