Attempting to create very simple game need MAJOR help

I've been trying this very simple game for 2 days now. Ive ran into how to make a keyevent problem, got that fixed. Now i want it so when a certain key is pressed it moves an image element on the screen. I cannot figure it out and im getter very frustrated.

Here is my fxml <?import javafx.scene.control.Button?> <?import javafx.scene.effect.DropShadow?> <?import javafx.scene.effect.Glow?> <?import javafx.scene.image.Image?> <?import javafx.scene.image.ImageView?> <?import javafx.scene.layout.AnchorPane?> <?import javafx.scene.shape.Rectangle?>

      <AnchorPane  maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity"

Here is my Controller start event 

    package sample;


   import javafx.animation.AnimationTimer;
   import javafx.event.ActionEvent;
   import javafx.event.EventHandler;
 import javafx.fxml.FXML;
            import javafx.fxml.FXMLLoader;

   import javafx.scene.image.Image;
   import javafx.scene.image.ImageView;
   import javafx.scene.input.KeyCode;
   import javafx.scene.input.KeyEvent;
   import javafx.stage.Stage;

   import java.util.ArrayList;


    public class Controller{
        Main mainOb = new Main();
        boolean right = false;
        double whiteX = 320;
        double blackX = 320;

@FXML
public ImageView whiteShipID;


public void playGame(ActionEvent event) throws Exception{
    Parent d = FXMLLoader.load(getClass().getResource("../style/play.fxml"));


    Stage playStage = new Stage();

    Scene scene = new Scene(d);
    scene.getStylesheets().add("/style/stylesheet.css");
    playStage.setTitle("Titan Clash");
    playStage.setScene(scene);
    playStage.show();

    if(whiteShipID == null) {
        System.out.println("Null");
    }





    ArrayList<String> input = new ArrayList<String>();

    scene.setOnKeyPressed(
            new EventHandler<KeyEvent>() {
                public void handle(KeyEvent e) {
                    String code = e.getCode().toString();

                    // only add once... prevent duplicates
                    if (!input.contains(code))
                        input.add(code);
                    System.out.println(input);
                    if(input.contains("RIGHT")) {
                        right = true;

                    }
                }
            });


    scene.setOnKeyReleased(
            new EventHandler<KeyEvent>() {
                public void handle(KeyEvent e) {
                    String code = e.getCode().toString();
                    input.remove(code);
                    right = false;
                }
            });
    AnimationTimer animate = new AnimationTimer() {

        public void handle(long arg0) {
            if(right) {
                whiteX+=3;
                System.out.println(whiteX);
            }
        }
    };
    animate.start();
