Temps Reel Java

[Aleskweb]

Merci, juste:
J'ai ce code tout simple :

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.Timer;

import javafx.scene.Group;

import javafx.scene.Parent;

/**

 *

 * @author TheTrope

 */

public class Rendu extends Parent{

    

    int x = 0;

    Group Ecran = new Group();

    Map nmap;

   

    

    public Rendu()

    {

        

       Map nmap = new Map(1,400,100);

       Ecran.getChildren().add(nmap);

       this.getChildren().add(Ecran);

       new Timer(33,taskPerformer).start();

       

    }

    

    ActionListener taskPerformer = new ActionListener() {

      public void actionPerformed(ActionEvent evt) {

          nmap.setx(x);

          System.out.println("Render");

          x++;

          }

  };

    

     

}

Ma classe Map génère une map 2d iso et l'affiche.
Voici la classe en question :

import javafx.scene.Parent;

import javafx.scene.Group;



public class Map extends Parent{

    

    private int x;

    private int y;

    private int startx;

    private int starty;

    

    private int cl_mx;

    private int cl_my;

    private Group partMap = new Group();

    

   public Map(int id, int mx, int my){



    startx = mx;

    starty = my;

    x = startx;

    y = starty;

    int currentx = 0;

    int currenty = 0;

    while (currenty<13){

        while (currentx<13){

            Tile tile = new Tile(1, x, y);

            partMap.getChildren().add(tile);

            x = x + 34;

            y = y + 17;

            currentx++;

           

        }

        currenty++;

        x = startx -currenty*34;

        y = starty + currenty*17;

       

        currentx=0;

        

         

    }

    System.out.println("map cree");

   

    this.getChildren().add(partMap);

}



     public void setx(int x)

   {

       partMap.setTranslateX(x);

   } 



   

}

Normalement, a chaque "timer" cela devrait déplacer le groupe partMap et donc je devrais voir ma Map se déplacer vers la droite. Mais a la place, j'ai cette erreur :

Code :

Si vous avez une idée?

Merci d'avance
