带有场景构建器事件的java连接控制器

Question

如何使用场景生成器连接键盘/鼠标等事件？？ 我的代码如下所示：

@FXML 
    public void onKeyPressed() {
          group.getScene().setOnKeyPressed(event -> {
              double change = 10.0;
              if(event.isShiftDown()) { change = 50.0; }
              KeyCode keycode = event.getCode();
              if(keycode == KeyCode.W) { perspectiveCamera.setTranslateZ(perspectiveCamera.getTranslateZ() + change); }
              if(keycode == KeyCode.S) { perspectiveCamera.setTranslateZ(perspectiveCamera.getTranslateZ() - change); }
              if(keycode == KeyCode.A) { perspectiveCamera.setTranslateX(perspectiveCamera.getTranslateX() - change); }
              if(keycode == KeyCode.D) { perspectiveCamera.setTranslateX(perspectiveCamera.getTranslateX() + change); }
          });    
    }
    @FXML
    public void onMousePressed() {
        group.getScene().setOnMousePressed((MouseEvent me) -> {
             mousePosX = me.getSceneX();
             mousePosY = me.getSceneY();
             mouseOldX = me.getSceneX();
             mouseOldY = me.getSceneY();
         });
    }
    @FXML
    public void onMouseDragged() {
        group.getScene().setOnMouseDragged((MouseEvent me) -> {
            mouseOldX = mousePosX;
            mouseOldY = mousePosY;
            mousePosX = me.getSceneX();
            mousePosY = me.getSceneY();
            mouseDeltaX = (mousePosX - mouseOldX);
            mouseDeltaY = (mousePosY - mouseOldY);

            double modifier = 10.0;
            double modifierFactor = 0.1;

            if (me.isControlDown()) {
                modifier = 0.1;
            }
            if (me.isShiftDown()) {
                modifier = 50.0;
            }
            if (me.isPrimaryButtonDown()) {
                cameraTransformer.ry.setAngle(((cameraTransformer.ry.getAngle() + mouseDeltaX * modifierFactor * modifier * 2.0) % 360 + 540) % 360 - 180);  // +
                cameraTransformer.rx.setAngle(((cameraTransformer.rx.getAngle() - mouseDeltaY * modifierFactor * modifier * 2.0) % 360 + 540) % 360 - 180);  // -
            } else if (me.isSecondaryButtonDown()) {
                double z = perspectiveCamera.getTranslateZ();
                double newZ = z + mouseDeltaX * modifierFactor * modifier;
                perspectiveCamera.setTranslateZ(newZ);
            } else if (me.isMiddleButtonDown()) {
                cameraTransformer.t.setX(cameraTransformer.t.getX() + mouseDeltaX * modifierFactor * modifier * 0.3);  // -
                cameraTransformer.t.setY(cameraTransformer.t.getY() + mouseDeltaY * modifierFactor * modifier * 0.3);  // -
            }
        });
    }

以及“场景生成器”面板：

我通常都是用同样的方法，它可以工作，但现在使用这个面板就不行了。我哪里做错了
