JavaFX春节祝福——我用Java摆烂了你的AE作业

一、效果图

 

 

二、 代码部分

1.SpringFestival类：

        1.创建时间轴，将SpringFestivalAnimation类（下面）的动画作为关键帧插入

        2.时间轴随着time值的累加而运行

        3.将若干关键帧加入到timeline时间轴中

public class SpringFestival extends Application {

    private static String url = SpringFestival.class.getResource("/music/chunJieXuQu.mp3").toString();
    private double second = 1000;
    private double time = 0.001;

    public static void main(String[] args) {
        //播放音乐
        MediaPlayer player = new MediaPlayer(new Media(url));
        player.play();

        Application.launch(args);
    }

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

        BorderPane pane = new BorderPane();

        // 设置背景图片
        ImagePattern imagePattern = new ImagePattern(new Image("/image/background.jpg"), 0, 0, 1, 1, true);
        pane.setBackground(new Background(new BackgroundFill(imagePattern, CornerRadii.EMPTY, Insets.EMPTY)));

        SpringFestivalAnimation animation_top = new SpringFestivalAnimation();
        animation_top.setAlignment(Pos.CENTER);

        SpringFestivalAnimation animation_left = new SpringFestivalAnimation();
        animation_left.setAlignment(Pos.CENTER_LEFT);

        SpringFestivalAnimation animation_center = new SpringFestivalAnimation();
        animation_center.setAlignment(Pos.CENTER);

        SpringFestivalAnimation animation_right = new SpringFestivalAnimation();
        animation_right.setAlignment(Pos.CENTER_RIGHT);

        // 创建时间轴
        Timeline timeline = new Timeline();
        timeline.setAutoReverse(true);

        // 插入关键帧动画
        KeyFrame rotate_left = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {

                animation_left.rotate(1, 0);

            }
        });

        time += 1;

        KeyFrame rotate_center = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {

                animation_center.rotate(1, 0);

            }
        });

        time += 1;

        KeyFrame rotate_right = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {

                animation_right.rotate(9, 5);

            }
        });

        time += 9;

        KeyFrame move_slow = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {
                // 设置新背景图片
                ImagePattern imagePattern = new ImagePattern(new Image("/image/snow.png"), 0, 0, 1, 1, true);
                pane.setBackground(new Background(new BackgroundFill(imagePattern, CornerRadii.EMPTY, Insets.EMPTY)));
                animation_left.move_slow();
                animation_center.move_slow();
                animation_right.move_slow();

                animation_right.move_fast();

            }
        });

        time += 2;

                animation_center.move_nomal();
                animation_right.move_nomal();
            }
        });

        time += 3.2;

        KeyFrame duiLian_left = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {

                animation_left.duiLian(new ImageView("/image/duilian_left.jpg"));

            }
        });

        time += 1;

        KeyFrame duiLian_head = new KeyFrame(Duration.millis(time * second), new EventHandler<ActionEvent>() {
            public void handle(ActionEvent t) {

                animation_top.duiLian(new ImageView("/image/duilian_head.jpg"));

            }

        primaryStage.getIcons().add(new Image(getClass().getResourceAsStream("/image/Fu.png")));
        primaryStage.show();
    }

}

2.SpringFestivalAnimation类

        1.“福”的旋转（RotateTransition），放大（ScaleTransition）

        2.“灯笼”按路径（Path）鬼畜走位，正常移动（TranslateTransition）

        3.“对联”的淡入淡出（FadeTransition）

public class SpringFestivalAnimation extends VBox {
    private Path path;
    private ImageView view;

    public SpringFestivalAnimation() {
        setPadding(new Insets(30));
    }

    public void rotate(double time, double speed) {
        view = new ImageView("/image/Fu.png");
        view.setFitHeight(100);
        view.setFitWidth(100);
        getChildren().addAll(view);

        // 旋转
        RotateTransition rotateTransition = new RotateTransition(Duration.millis(1000 * time), view);
        rotateTransition.setByAngle(360 * ((360 + 45) / 360.0 + speed));

        ParallelTransition parallelTransition = new ParallelTransition();

        if (time == 9) {
            parallelTransition.getChildren().addAll(

        } else {
            parallelTransition.getChildren().addAll(
                    rotateTransition

三、总结

1.图片音乐等资源可以在github上直接获取（为了摆烂，特意找了有水印的）OracleRay/SpringFestival: 欢度春节 (github.com)icon-default.png?t=LBL2https://github.com/OracleRay/SpringFestival2.代码还存在诸多bug（反正也是摆烂，正经人谁用JavaFX做动画......），没事儿的hxd可以试着粘过去改改bug哈哈哈
