java实现桌球游戏

下面我来详细讲解一下“Java实现桌球游戏”的完整攻略，具体内容如下：

准备工作

首先，我们需要准备以下开发工具：

• Eclipse IDE
• JDK
• JavaFX Scene Builder

安装完毕后，打开Eclipse IDE，在新建Java工程时，选择JavaFX项目，并在项目中导入JavaFX语言库。

编写桌球游戏程序

UI设计

使用JavaFX Scene Builder，设计游戏界面。包含以下几个元素：

• 两个球拍
• 一个球
• 游戏得分
• 游戏时间

实现游戏界面

通过JavaFX代码实现游戏界面，主要实现以下几个功能：

• 绘制界面中的球拍和球
• 实现球拍的控制
• 实现球的控制
• 当球碰到边界或球拍时，实现反弹效果

实现游戏得分和计时

• 实现计分器的控制
• 实现计时器的控制

测试应用程序

最后，我们需要测试应用程序，确保其运行正常。在测试过程中，我们需要注意以下几个问题：

• 碰撞检测是否正常
• 游戏时间和得分是否准确
• 界面是否流畅

下面是一个示例代码实现：

public class Main extends Application {

    private Ball ball;
    private Paddle paddle1;
    private Paddle paddle2;
    private Group root;
    private Scene scene;
    private Timeline timeline;
    private boolean gameRunning = true;
    private Text timerText;
    private Text pointText;
    private int point1 = 0;
    private int point2 = 0;
    private DateTimeFormatter formatter;
    private LocalTime time;
    private LocalTime startTime;
    private MediaPlayer mediaPlayer;

    @Override
    public void start(Stage primaryStage) {
        // Initialize the scene and root
        root = new Group();
        scene = new Scene(root, 600, 400, Color.BLACK);

        // Initialize the ball, paddle1, paddle2, and game timer/point counter
        ball = new Ball(10, Color.RED);
        paddle1 = new Paddle(Color.AQUA, 20, scene.getHeight());
        paddle2 = new Paddle(Color.YELLOW, scene.getWidth()-20, scene.getHeight());
        timerText = new Text(20, 25, "");
        pointText = new Text(scene.getWidth()-60, 25, "0 - 0");
        startTime = LocalTime.now();
        formatter = DateTimeFormatter.ofPattern("mm:ss");
        time = LocalTime.of(0, 0);

        // Add all objects to the scene and root
        root.getChildren().add(ball.getCircle());
        root.getChildren().add(paddle1.getRectangle());
        root.getChildren().add(paddle2.getRectangle());
        root.getChildren().add(timerText);
        root.getChildren().add(pointText);

        // Add key event listeners for Paddle1
        scene.setOnKeyPressed(new EventHandler<KeyEvent>() {

            @Override
            public void handle(KeyEvent event) {

                if (event.getCode() == KeyCode.W) {
                    paddle1.setMoveUp(true);
                }
                else if (event.getCode() == KeyCode.S) {
                    paddle1.setMoveDown(true);
                }
            }

        });

        scene.setOnKeyReleased(new EventHandler<KeyEvent>() {

            @Override
            public void handle(KeyEvent event) {

                if (event.getCode() == KeyCode.W) {
                    paddle1.setMoveUp(false);
                }
                else if (event.getCode() == KeyCode.S) {
                    paddle1.setMoveDown(false);
                }
            }

        });

        // Add timeline for game loop
        timeline = new Timeline(new KeyFrame(Duration.millis(16), new EventHandler<ActionEvent>() {

            @Override
            public void handle(ActionEvent arg0) {
                // Add time to timer
                time = LocalTime.now().minusNanos(startTime.toNanoOfDay());
                timerText.setText(formatter.format(time));

                // Move paddles
                paddle1.move();
                paddle2.move(ball);

                // Check for collisions with paddles
                if (ball.intersects(paddle1) || ball.intersects(paddle2)) {
                    mediaPlayer = new MediaPlayer(new Media(getClass().getResource("/sounds/blip.mp3").toString()));
                    mediaPlayer.setVolume(0.3);
                    mediaPlayer.play();
                    ball.bounce();
                }

                // Check for collisions with walls
                if (ball.getCenterY() <= (ball.getRadius()) || ball.getCenterY() >= (scene.getHeight() - ball.getRadius())) {
                    ball.bounceY();
                }

                // Check for scoring
                if (ball.getCenterX() <= 0) {
                    point2++;
                    pointText.setText(point1 + " - " + point2);
                    ball.reset();
                }
                else if (ball.getCenterX() >= scene.getWidth()) {
                    point1++;
                    pointText.setText(point1 + " - " + point2);
                    ball.reset();
                }

                // End the game
                if (point1 == 10 || point2 == 10) {
                    gameRunning = false;
                    timeline.stop();
                    mediaPlayer = new MediaPlayer(new Media(getClass().getResource("/sounds/gameover.mp3").toString()));
                    mediaPlayer.setVolume(0.5);
                    mediaPlayer.play();
                }

                // Move ball
                ball.move();

            }

        }));

        timeline.setCycleCount(Timeline.INDEFINITE);
        timeline.play();

        // Set the stage
        primaryStage.setTitle("Pong");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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

上面示例代码中的Ball、Paddle及其他辅助类方法并未给出，仅是提供一个基本的框架代码，请读者自行编写并加以完善。
