正在更新 javafx 中的 TicTacToe UI

Question

这里有一段代码是为了理解java中的TicTacToe游戏代码从网上收集的。我了解代码的编写方式及其逻辑。它在单个 window 中播放，其中两个用户根据单击的鼠标按钮进行区分。现在我想做一个类似的游戏，可以在由服务器和客户端构建的网络上玩。

TicTacToe.java

public class Main extends Application {

    private boolean playable = true;
    private boolean turnX = true;
    private Tile[][] board = new Tile[3][3];
    private List<Combo> combos = new ArrayList<>();

    private Pane root = new Pane();

    private Parent createContent() {
        root.setPrefSize(600, 600);

        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                Tile tile = new Tile(); //each tile is a rectangular block
                tile.setTranslateX(j * 200);
                tile.setTranslateY(i * 200);

                root.getChildren().add(tile);

                board[j][i] = tile;
            }
        }

        // horizontal
        for (int y = 0; y < 3; y++) {
            combos.add(new Combo(board[0][y], board[1][y], board[2][y]));
        }

        // vertical
        for (int x = 0; x < 3; x++) {
            combos.add(new Combo(board[x][0], board[x][1], board[x][2]));
        }

        // diagonals
        combos.add(new Combo(board[0][0], board[1][1], board[2][2]));
        combos.add(new Combo(board[2][0], board[1][1], board[0][2]));

        return root;
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setScene(new Scene(createContent()));
        primaryStage.show();
    }

    private void checkState() {
        for (Combo combo : combos) {
            if (combo.isComplete()) {
                playable = false;
                playWinAnimation(combo);
                break;
            }
        }
    }

    private void playWinAnimation(Combo combo) {
        Line line = new Line();
        line.setStartX(combo.tiles[0].getCenterX());
        line.setStartY(combo.tiles[0].getCenterY());
        line.setEndX(combo.tiles[0].getCenterX());
        line.setEndY(combo.tiles[0].getCenterY());

        root.getChildren().add(line);

        Timeline timeline = new Timeline();
        timeline.getKeyFrames().add(new KeyFrame(Duration.seconds(1),
                new KeyValue(line.endXProperty(), combo.tiles[2].getCenterX()),
                new KeyValue(line.endYProperty(), combo.tiles[2].getCenterY())));
        timeline.play();
    }

    private class Combo {
        private Tile[] tiles;
        public Combo(Tile... tiles) {
            this.tiles = tiles;
        }

        public boolean isComplete() {
            if (tiles[0].getValue().isEmpty())
                return false;

            return tiles[0].getValue().equals(tiles[1].getValue())
                    && tiles[0].getValue().equals(tiles[2].getValue());
        }
    }

    private class Tile extends StackPane {
        private Text text = new Text();
        private boolean clicked = false;;

        public Tile() {
            Rectangle border = new Rectangle(200, 200);
            border.setFill(null);
            border.setStroke(Color.BLACK);

            text.setFont(Font.font(72));

            setAlignment(Pos.CENTER);
            getChildren().addAll(border, text);

            setOnMouseClicked(event -> {
                if (!playable || clicked)
                    return;

                if (event.getButton() == MouseButton.PRIMARY) {
                    if (!turnX)
                        return;

                    if(!clicked){
                        drawX();
                        turnX = false;
                        clicked = true;
                        checkState();
                    }
                }
                else if (event.getButton() == MouseButton.SECONDARY) {
                    if (turnX)
                        return;

                    if(!clicked){
                        drawO();
                        turnX = true;
                        clicked = true;
                        checkState();
                    }
                }
            });
        }

        public double getCenterX() {
            return getTranslateX() + 100;
        }

        public double getCenterY() {
            return getTranslateY() + 100;
        }

        public String getValue() {
            return text.getText();
        }

        private void drawX() {
            text.setText("X");
        }

        private void drawO() {
            text.setText("O");
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}

我想在不同的文件中构建服务器和客户端。 server.java 将包含服务器套接字、输入输出流，并接受来自套接字的连接。对于那件事我没有任何疑问。同样，client.java 也将有套接字和必要的流。服务器文件和客户端文件也将具有 TicTacToe.java。我可以设置代码到此为止。

我的问题：

我无法通过套接字网络更新 UI。我该怎么做？我看过一些关于 Platform.runLater() 的代码，但不太理解它们。我想要洞察力。

如果有人可以指导我如何为此编写代码并实现我想要的，以便我可以解决我的问题，那将对我非常有帮助。

谢谢...

为了使用 Platform.RunLater 函数，我所做的是创建一个后台线程来接收来自 client/server 的数据包。然后使用 platform.runLater 函数更新 UI...

private ScheduledExecutorService scheduledPINGExecutorService;
private ScheduledFuture<?>       scheduledPINGCheck;

public static void main(String[] args){
        launch(args);
}
@Override
public void start(Stage primaryStage){
        primaryStage.setTitle("Title");

        primaryStage.setScene(new Scene(getMainPage(primaryStage), 800, 1000));
        primaryStage.show();

scheduledPINGExecutorService = Executors.newScheduledThreadPool(1);

Runnable checkPING = () -> {
            //check for new packet from client
            getData() <---- define this function depending on your networking setup
            Platform.runLater(() -> { //populate UI with new data  });
        };
scheduledPINGCheck = scheduledPINGExecutorService.scheduleAtFixedRate(checkPING, 1, 500, TimeUnit.MILLISECONDS);

    }
