如何在 Gomoku javafx 游戏中启用轮流 [关闭]

Question

在我的程序中启用轮换时遇到困难。

棋盘上的一个图块被点击，这些坐标被传递给 playMakeMove()，它在棋盘矩阵中进行移动并设置文本以直观地表示移动。

虽然当涉及 2 个玩家（玩家，RandomAI）时，在使用循环交替回合后，该方法不起作用。 RandomAI 只是连续移动所有动作，玩家只在完全相同的位置移动一次（不等待鼠标点击）。

我认为这个问题可以通过等待一个瓷砖被点击（运行方法 playerMakeMove）然后让 RandomAI 轮流来解决。不知道如何实现这一点。

下面是两个类 BoardGUI 和 Game，还有另一个类（不包括在内）称为 Board。

public class BoardGUI extends Application {

    private final int BOARD_SIZE = 15;

    private Tile[][] tileBoard = new Tile[BOARD_SIZE][BOARD_SIZE];

    private Pane root = new Pane();

    private Parent createContent(Game game) {
        root.setPrefSize(755, 755);

        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                Tile tile = new Tile(i, j);
                tile.setTranslateX(j * 50);
                tile.setTranslateY(i * 50);

                tile.setOnMousePressed(e -> {
                    System.out.println("tile clicked");

                    // sets coordinates of tileClicked in game - to be used in making a player move
                    game.getTile().setRow(tile.getTileRow());
                    game.getTile().setColumn(tile.getTileCol());
                });

                root.getChildren().add(tile);

                tileBoard[i][j] = tile;
            }

        return root;
    }

Answer 1

您有 2 个主要选项来实现游戏循环。我只提供伪代码，而不是用 Java 编写它们的等价物，您可以询问是否在转换为 Java 时遇到问题。

第一个选项是触发用户采取行动的所有活动。因此，例如，“事件”可能是拖放、选项点击等，具体取决于游戏：

on user event:
    change state according to user's choice
    go to next player
    while next player is AI:
        perform automated move
        go to next player

第二个更通用的选项是设置一个定期触发的计时器，以检查是否可以发生 AI 动作。

on user event:
    change state according to user's choice
    go to next player

on timer tick:
    if current player is AI
       perform automated move
       go to next player

根据游戏机制，每一个都有自己的位置

下面是一个完整的可运行代码，实现了轮换。
它还提出了一些改进和设计更改。请注意 cmets。
游戏结束逻辑未实现。
