Getting character to jump in JavaFX

I have tried using a KeyListener to make the character rise which just simply didnt do anything. Is there a better way to do this? If not, does anyone know why the KeyListener isn't working? I would really appreciate some help. Also, I call this method in a Timeline so the bird does not just fall 1 pixel and will not rise by one either

Here is the code for the KeyListener (The bird falling part works fine by the way):

public static void birdJump() {

        birdView.relocate(100, fall++);
        if(fall > 201)
        birdView.setRotate(50);

        FlappyBird.root.setOnKeyPressed(new EventHandler<KeyEvent>() {
            @Override
            public void handle(KeyEvent event) {
                if (event.getCode().equals(32)) {

                    birdView.relocate(100, fall--);
                    if(fall > 199)
                    birdView.setRotate(-50);

                }
            }
        });
     }

Thanks!

In addition to what James_D said, I think it's because you use the KeyEvent on a Layout that does not have the focus by default since it belongs to the Scene, to remedy it you have to give it the focus :

root.setFocusTransversale(true); /* Enable focus on the layout */
root.requestFocus();  /* give the focus to the layout */

I hope this will solve your problem !

Read the documentation: event.getCode() does not return an int (or a number of any kind), so event.getCode().equals(32) cannot possibly be true.

You want

if (event.getKeyCode() == KeyCode.SPACE) {
    // ...
}
