Question

我正在用javafx创建老虎机应用程序。期望的行为：分离的图片必须在动画期间出现在窗格中作为真正的老虎机鼓（樱桃，柠檬，数字服务器等的图片应该看起来像用户的整个和平），如在图片上显示。

我的问题是我无法将单独的图像放在一起，无缝地在老虎机窗口中滚动。我已经对此问题进行了大量搜索，但没有找到任何有效的解决方案。我试图在ArrayList中添加所有图像，然后在动画过程中将它们设置为TranslateTransition引用的节点。但是Windows中的初始图像堆栈。

import javafx.animation.ParallelTransition;

import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
import javafx.util.Duration;

public class TestClass extends Application {

private BorderPane borderPane = new BorderPane();
private GridPane gridPane = new GridPane();

@Override
public void start(Stage primaryStage) throws Exception {

    ImageView image1 = new ImageView(createImage(Color.RED));
    ImageView image2 = new ImageView(createImage(Color.GREEN));
    ImageView image3 = new ImageView(createImage(Color.BLUE));

    gridPane.setLayoutX(50);
    gridPane.setLayoutY(50);
    gridPane.setPadding(new Insets(5, 5, 5, 5));
    gridPane.setAlignment(Pos.CENTER);
    gridPane.setVgap(5);

    gridPane.add(image1, 0, 0);
    gridPane.add(image2, 1, 0);
    gridPane.add(image3, 2, 0);
    gridPane.setMaxWidth(image1.getFitWidth() * 3);
    gridPane.setMaxHeight(image1.getFitHeight());

    Rectangle clip = new Rectangle(732, 230);
    clip.setLayoutX(30);
    clip.setLayoutY(10);
    clip.setStroke(Color.BLACK);

    // clip.setFill(null);

    gridPane.setClip(clip);

    borderPane.setCenter(gridPane);
    Scene scene = new Scene(borderPane, 900, 500);
    primaryStage.setScene(scene);
    primaryStage.setTitle("SlotMachine");
    primaryStage.show();

    ImageView[] images = { image1, image2, image3 };

    TranslateTransition t1 = new TranslateTransition();
    for (ImageView i : images) {

        t1.setDuration(Duration.millis(2000));
        t1.setNode(i);
        t1.setFromX(image1.getX());
        t1.setFromY(image1.getY() - gridPane.getHeight());
        t1.setToX(image1.getX());
        t1.setToY(image1.getY() - image1.getFitHeight() / 2 + gridPane.getHeight());
        t1.setCycleCount(2);

        t1.setAutoReverse(false);
        t1.setInterpolator(Interpolator.LINEAR);
    }

    TranslateTransition t2 = new TranslateTransition();
    for (ImageView i : images) {

        t2.setDuration(Duration.millis(2000));
        t2.setNode(i);
        t2.setFromX(image2.getX());
        t2.setFromY(image2.getY() - gridPane.getHeight());
        t2.setToX(image2.getX());
        t2.setToY(image2.getY() - image2.getFitHeight() / 2 + gridPane.getHeight());
        t2.setCycleCount(2);

        t2.setAutoReverse(false);
        t2.setInterpolator(Interpolator.LINEAR);
    }

    TranslateTransition t3 = new TranslateTransition();
    for (ImageView i : images) {

        t3.setDuration(Duration.millis(2000));
        t3.setNode(i);
        t3.setFromX(image3.getX());
        t3.setFromY(image3.getY() - gridPane.getHeight());
        t3.setToX(image3.getX());
        t3.setToY(image3.getY() - image3.getFitHeight() / 2 + gridPane.getHeight());
        t3.setCycleCount(2);

        t3.setAutoReverse(false);
        t3.setInterpolator(Interpolator.LINEAR);
    }

    ParallelTransition pt = new ParallelTransition(t2, t3, t1);
    pt.play();
}

private final Image createImage(Color color) {
    Rectangle rect = new Rectangle(32, 32);
    rect.setFill(color);
    return rect.snapshot(null, null);

}

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

} 请帮忙。提前谢谢

据我所知，它看起来并不像你在使用模型/视图/控制器架构;使用这种架构是（在我看来）最简单的方法来实现这样的gui。在您的情况下，您可以从以下伪代码建模您的逻辑：

在控制器中：

//changes x or y coordinate (depending on direction of movement) of top left corner
//the controller should change the values of x or y that are stored in your model    
moveImageMethod(image);

在视图中

//Number of ms between timer events, play with this number to make it smooth
private static final int TIMER_INTERVAL = 1000/30;

//constructor
public View(){
    <your other stuff, event handlers, etc.>
    this.timer = new Timer(TIMER_INTERVAL, new ActionListener() { 
            @Override 
            public void actionPerformed(ActionEvent e) { 
                   handleTimerTick(); 
            } 
     }); 
}

// Start the animation timer. 
public void startTimer() { 
       timer.start(); 
} 

protected void handleTimerTick(){
    controller.moveImageMethod(image);
    <other stuff you might need/want>
    repaint();
}

<your graphics methods>
