Is that a normal decision or am I missing something?

Airplane class

 public class Airplane extends BasicObject {
public Airplane(){

    // по центру экрана
    x = MyMainClass.WIDTH/2;
    y = MyMainClass.HEIGHT/2;
    dx = speed = 200;

    // делаю прямоугольник
    rectangle = new Rectangle();
    rectangle.x = x;
    rectangle.y = y;
    rectangle.width = 64;
    rectangle.height = 64;

    // как самолет будет выглядеть
    texture = new Texture("AIRPLANE.png");
    sprite = new Sprite(texture);

    // позиция спрайта соответствует позиции прямоугольника
    sprite.setPosition(rectangle.x, rectangle.y);

public void update(float dt){
// если нажать B, то x сдвинется вправо, прямоугольник движется за x,

// а позиция спрайта становится равной позиции прямоугольника

if(Gdx.input.isKeyJustPressed(Input.Keys.В)) {
        x += dx * dt;
        rectangle.x = x;

        sprite.setPosition(rectangle.x, rectangle.y);
    }
}

Now the question is, isn't it too much? update()or is that normal and should we do it? If you remove it. sprite.setPosition(rectangle.x, rectangle.y); or rectangle.x = x;There's no movement. x changing. So, is it okay or is there a better solution?

Maybe it's better for some kind of manager to add a compression to pick up and send a message (or callback interface) to all signatory, reporting a state like Publisher-Subscriber.
