在何处以及如何实例化inputmap和actionmap

我正在制作经典的“在屏幕上四处移动图像”程序。我正在尝试使用键盘绑定代替键侦听器，但是到目前为止没有成功。

我的对象在链表中

public LinkedList<GameObject> object = new LinkedList<GameObject>();

并通过添加到此列表中

public void addObject(GameObject object){
    this.object.add(object);
}

我的KeyBinding类如下

public class KeyBindings extends JPanel{

private static final String accelerate = "accelerate";

public KeyBindings(){
    System.out.println("test");
    registerKeyBinding(KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0, false), "UP-press", new ShuttleMove(accelerate));
}

public void registerKeyBinding(KeyStroke keyStroke, String name, Action action) {
    InputMap im = getInputMap(WHEN_IN_FOCUSED_WINDOW);
    ActionMap am = getActionMap();

    im.put(keyStroke, name);
    am.put(name, action);
}

class ShuttleMove extends AbstractAction {

    public ShuttleMove(String movement) {

            if (movement.equals("accelerate")){
                //this.setVelocityForward(this.getVelocityForward() + 0.1);
                System.out.println("accelerate");
            }
    }
    public void actionPerformed(ActionEvent e) {
    }
}

}

我的Player类（扩展了GameObject类）看起来（略有浓缩）为：

public class Player extends GameObject {

Handler handler;

public Player(int x, int y, ID id, int width, int height, int rotation,double totalRotation, Handler handler, double velocityForward, double velocityRotate){
    super(x, y, id, width, height, rotation, totalRotation);
    this.handler = handler;

}

public void tick(){ 
    x += this.getVelocityForward();
    y += this.getVelocityForward();
}
public void render(Graphics2D g2d){

    try {
        player = ImageIO.read(new File("src/Game/images/shuttle3.png"));
    } catch (IOException e) {
        e.printStackTrace();
    }

    AffineTransform old = g2d.getTransform();
    AffineTransform at = AffineTransform.getTranslateInstance(x,y);     

    g2d.drawImage(player, at,null);
    g2d.setTransform(old);
}
}

我不确定如何“激活”键绑定。应该在主循环中吗？是否应该在player.tick方法中调用该方法来更新播放器图像并随后绘制它？

另外，inputmap和actionmap如何与玩家对象关联？我尝试做类似的事情，但是没有用：

public void registerKeyBinding(KeyStroke keyStroke, String name, Action action) {
    for (int i = 0; i < handler.object.size(); i++){
        GameObject player = handler.object.get(i);
        //find player
        if (player.getID() == ID.Player){
            InputMap im = player.getInputMap(WHEN_IN_FOCUSED_WINDOW);
            ActionMap am = player.getActionMap();

            im.put(keyStroke, name);
            am.put(name, action);
        }
    }
}

我认为应该将播放器强制转换为JComponent，但我不确定如何完成（如Eclipse告诉我它与GameObject类不兼容）。谁能指导我正确的方向？如果我不小心遗漏了一些重要信息，请告诉我（我确信我确实做到了）
