我正在使用 javafx 创建老虎机应用程序。期望的行为：在动画期间，分离的图片必须像真正的老虎机鼓一样出现在窗格中（樱桃、柠檬、数字服务器等的图片对用户来说应该看起来像一个完整的和平），就像在图片上显示一样。

老虎机

我的问题是我无法将单独的图像放在一起以在老虎机窗口中无缝滚动。我对这个问题进行了很多搜索，但没有找到任何可行的解决方案。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.Interpolator;
import javafx.animation.ParallelTransition;
import javafx.animation.TranslateTransition;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.GridPane;
import javafx.scene.paint.Color;
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。先感谢您

据我所知，您似乎没有使用模型/视图/控制器架构；使用这种架构是（在我看来）实现这样的 gui 的最简单方法。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>
