}

这是图 block 类

我不明白当我改变难度时如何基本上重置棋盘，或者当我计划设置自定义棋盘选项时如何根据给定的图 block 数量自动调整棋盘大小。

如果你不知道...我对代码还很陌生。感谢您的帮助。

Answer 1

这不是已经完成大部分了吗？

    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);
    }

有人从菜单中选择一个选项会触发一个事件。事件处理程序包含一个 if/else block ，该 block 可以:退出、设置为简单、设置为中等、设置为困难。据我所知，makeBoard 函数处理灰色图 block 的实际显示，所有图 block 的 Occupied 设置为“g”(灰色？)。如果你问的是炸弹的实际生成等。我没有看到任何相关内容。它要么已为您处理好但您没有提供代码，要么您必须自己编写代码。

您需要将 int easyFlags 设置为针对该特定难度获得的任意数量。您需要将 flagCounter 标签设置为 0。您需要将计时器标签 t0 设置为 0。您需要根据难度将内部地雷设置为任意数量。

对于 menu.equals("Easy") if block ，它会是这样的:

    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;
    }

可能还有更多，但我不想为你做显然是某种学校项目的事情，哈哈
