How to draw same sprite in multiple box2d object layers.?

Question

I am working on a game, it is my first time...I encountered a issue, that I cant help myself to solve. Lets cut to the chase, I have a coin class, It draws coins to the only one box2D body, but In that layer(which I made in tiled), I have more 1 body but coin appears in only 1 of them, the last one. I want the coin texture to appear in all the object layers I defined for coins,I will also post the picture to help understand my question better.Code and image for coin is give below;

public class Coin extends Sprite{


protected PlayScreen screen;
private Body body;
private BodyDef bodyDef;
private FixtureDef fixtureDef;
private PolygonShape polygonShape;


public Coin(PlayScreen screen, World world,TiledMap map) {
super(screen.getAtlas().findRegion("Gold"));
this.screen = screen;
this.bodyDef = new BodyDef();
this.fixtureDef = new FixtureDef();
this.polygonShape = new PolygonShape();

TextureRegion coinTexture = new TextureRegion(getTexture(),0,0,64,64);
setBounds(0, 0, 84 / trollVersusZombies.PPM, 84 / trollVersusZombies.PPM);
setRegion(coinTexture);

for(MapObject mapObject: map.getLayers().get(6).getObjects().getByType(RectangleMapObject.class))
{
Rectangle rectangle = ((RectangleMapObject)mapObject).getRectangle();

bodyDef.type = BodyDef.BodyType.StaticBody;
bodyDef.position.set((rectangle.getX() + rectangle.getWidth() / 2)/ trollVersusZombies.PPM, (rectangle.getY() + rectangle.getHeight() / 2) / trollVersusZombies.PPM);

body = world.createBody(bodyDef);

polygonShape.setAsBox(rectangle.getWidth() / 2 / trollVersusZombies.PPM, rectangle.getHeight() / 2 / trollVersusZombies.PPM);
fixtureDef.shape = polygonShape;

fixtureDef.isSensor = true;
body.createFixture(fixtureDef);




}


}

public void update()
{
setPosition(body.getPosition().x - getWidth() / 2, body.getPosition().y - getHeight() / 2);

}
}

FYI :

In my main playscreen class,I have declared and instantiated my coin class to pass revelant parameters and the update method of coin class is called in update method of main playscreen class, also in render method of playscreen class, I have called coin.draw(playscreen.batch), i.e;

public void update(float dt) {
//Other code...
coin.update();
}


public void render(float delta) {

//Other Code
gameScreen.batch.begin();
coin.draw(gameScreen.batch);
gameScreen.batch.end();
}

Problem is that you put all the bodies you created in 1 variable. As a result only the last created body stored in that variable. Instead you must create an array to store each created body and draw a sprite for each body position. If you want to use sprite-extended class you should better create separated 'Coin' object for each body, but using same texture region object. And better way is to create bodies and regions in separate class not in the constructor.

Example (this is pseudocode):

public class Main {
    private Array<Coin> coins = new Array<>();

    public void create(){
        TextureRegion region = assets.getAtlas().findRegion("Gold");
        for(MapObject mapObject : mapObjects){
            Body body = createBody(mapObject);
            Coin coin = new Coin(region, body)
            coins.add(coin);
        }
    }

    public void render(SpriteBatch batch){
        for(Coin coin : coins){
            coin.draw(batch);
        }
    }

    public Body createBody(MapObject mapObject){
        // here create body using map object
    }
}

public class Coin extends Sprite {

    private Body body;

    public Coin(TextureRegion region, Body body){
        super(region);
        this.body = body;
    }

    public void update(){
    // here update sprite position using body coordinates
    }
}

Hope it helps! )
