JavaFX获取鼠标方向

Scene scene = new Scene(root, width, height);
primaryStage.setScene(scene);

scene.setOnMouseMoved(event -> {
    double mouseX = event.getX();
    double mouseY = event.getY();
    // 处理鼠标位置信息
});

scene.setOnMouseMoved(event -> {
    double mouseX = event.getX();
    double mouseY = event.getY();
    
    // 获取上一次鼠标位置
    double lastMouseX = ...;
    double lastMouseY = ...;
    
    // 计算鼠标移动的差值
    double deltaX = mouseX - lastMouseX;
    double deltaY = mouseY - lastMouseY;
    
    // 判断鼠标移动方向
    if (deltaX > 0) {
        // 鼠标向右移动
    } else if (deltaX < 0) {
        // 鼠标向左移动
    }
    
    if (deltaY > 0) {
        // 鼠标向下移动
    } else if (deltaY < 0) {
        // 鼠标向上移动
    }
    
    // 更新上一次鼠标位置
    lastMouseX = mouseX;
    lastMouseY = mouseY;
});
