JavaFX场景上的多键按下

JavaFX场景上的多键按下

试试这个：

final BooleanProperty spacePressed = new SimpleBooleanProperty(false);final BooleanProperty rightPressed = new SimpleBooleanProperty(false);final BooleanBinding spaceAndRightPressed = spacePressed.and(rightPressed);// How to respond to both keys pressed together:spaceAndRightPressed.addListener(new ChangeListener<Boolean>() {    @Override    public void changed(Observablevalue<Boolean> obs, Boolean werePressed, Boolean arePressed) {        System.out.println("Space and right pressed together");    }});// Wire up properties to key events:scene.setonKeyPressed(new EventHandler<KeyEvent>() {    @Override    public void handle(KeyEvent ke) {        if (ke.getCode() == KeyCode.SPACE) { spacePressed.set(true);        } else if (ke.getCode() == KeyCode.RIGHT) { rightPressed.set(true);        }    }});scene.setonKeyReleased(new EventHandler<KeyEvent>() {    @Override    public void handle(KeyEvent ke) {        if (ke.getCode() == KeyCode.SPACE) { spacePressed.set(false);        } else if (ke.getCode() == KeyCode.RIGHT) { rightPressed.set(false);        }    }});
