Java - setLocation/Bounds sur un JLabel avec un ImageIcon ne fonctionne pas à partir d'une autre classe

Question

C'est ma première question alors donnez-moi des critiques si je peux faire quelque chose de mieux.

Lorsque j'appelle Hero.Move.MoveLeft(); le JLabel "labelHero" ne bougez pas visuellement. Mais le débogueur dit que posX change. La chose intéressante est que si j'appelle Hero.Move.MoveLeft(); avant que le gamePanel soit ajouté la première fois au Frame, cela fonctionne. (J'ai marqué la position au milieu de myWindow.)

Thx pour l'aide les gars.

package com.company.Game; 

import com.company.Characters.Hero; 

public class Main 
{ 

    public static void main(String[] args) 
    { 
     Hero.Initialize(); 
     myWindow myWindow = new myWindow(); 
     PaintObjects.PaintNew(); 
     myWindow.Repaint(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
     Hero.Move.MoveLeft(); 
    } 
}

Answer 1

Thx les gars,

J'ai trouvé le problème.

PaintObjects.PaintNew(); a été appelée deux fois. Une fois dans la méthode principale et une fois dans le constructeur myWindow. Cependant, le programme a perdu la connexion avec l'objet visible.
