使用循环的JavaFX动画？

import javafx.animation.AnimationTimer;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;

public class LoopingAnimationExample extends Application {

    private static final int WIDTH = 400;
    private static final int HEIGHT = 400;
    private static final int RADIUS = 50;

    @Override
    public void start(Stage primaryStage) {
        Circle circle = new Circle(RADIUS);

        StackPane root = new StackPane();
        root.getChildren().add(circle);

        Scene scene = new Scene(root, WIDTH, HEIGHT);
        primaryStage.setScene(scene);
        primaryStage.show();

        // 创建AnimationTimer对象
        AnimationTimer timer = new AnimationTimer() {
            @Override
            public void handle(long now) {
                // 在每一帧中更新动画状态
                // 这里可以执行具体的动画逻辑，如移动、旋转、缩放等
                circle.setRotate(circle.getRotate() + 1); // 使圆形旋转
            }
        };

        // 启动动画循环
        timer.start();
    }

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