我有一个问题，我有一个游戏，井字游戏，我不知道如何做到这一点，所以当有人获胜或有人移动时，它会挡住某个位置，而当有人获胜时，它不会让你做任何事情，它在 JFrame 内，我可以随时更改 O 和 X 这是代码

编辑：您似乎有两个“网格”。JFrame 版本使用labelValue和 Fame 版本gridMark。

  1. 删除字段和的声明gridMark，因为它们不应该被使用。numberClicksxTurn
  2. gridMark用替换所有引用labelValue。
  3. numberClicks用替换所有引用counter。
  4. 更改xTurn = true;为whosTurn = 0;。
  5. 替换绘图命令。（例如myGraphics.drawOval(x, y, 60, 60);）与choiceLabel[gridSelected].setIcon(imageX);

  6. 在调用checkWinner()in之后labelMouseClicked，插入：

    if (!gameHasEnded)
{
    makeMove();
}

一个提示：删除您在 JFrame 版本中未使用的所有字段。这将使所有对 Frame-version 变量的引用都被突出显示为错误。

在labelMouseClicked()您必须检查该字段是否已被单击。例如检查choiceLabel[choice].getBackground()：

if (choiceLabel[choice].getBackground().equal(Color.WHITE))
{
  // already clicked
  return;
}

要检查游戏是否结束，您可以返回一个布尔值，checkWinner()或者更好地为它创建一个新函数：isGameEnd(). 您可以在labelMouseClicked()和中使用它checkWinner()。
