JavaFx KeyEvent不会移动对象

Question

I am currently trying to just make a really simple game as an experiment of what can be done with JavaFX, and I have a little rectangle that represents a person. The rectangle is set in a pane, and I'm trying to figure out how best to make it so the arrow keys make him move 5 px over to the left. The code below is what I'm trying. If you know how to make this code work or have better code for it, I would be very grateful.

scene.setOnKeyPressed(new EventHandler<KeyEvent>() {
        @Override
        public void handle(KeyEvent ke) {
            if(ke.equals(KeyCode.KP_LEFT)) {
                int xLoc = (int)avatar.getX();
                int newX = xLoc - 5;
                int yLoc = (int)avatar.getY();
                avatar.relocate(newX, yLoc);
            }
        }
    });

Thank you!

KeyEvent不是代码，您需要getCode() 。

if (ke.getCode().equals(KeyCode.KP_LEFT))
