Java: mon MMORPG ne marche pas

Bonjour, je crée un MMORPG en java qui ne marche pas. je fais tout mon possible mais je ne comprend pas le problème: mon personnage ne veut pas se déplacer et l'updater ne marche pas(j'ai créer un fichier "fichier.txt"). voici le code ( deso si il est un peu crad):

Fen.java:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import java.awt.Toolkit;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
public class Fen extends JFrame{
public Fen(){
setTitle("MMORPG");
setSize(700,500);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setContentPane(new Map());
}
public static void main(String[] args) {
Updater mise_a_jour = new Updater();
Fen f = new Fen();
f.setVisible(true);
Map m = new Map();
}
}

Map.java:

import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.JPanel;

public class Map extends JPanel{
int coorX = 50;
int coorY = 50;
Graphics g;
public Map(){
addMouseListener(new Action());
}
public void paintComponent(Graphics g){
Image img;
Image img_perso;
try {
img = ImageIO.read(new File( "map.jpg"));
g.drawImage(img,0,0,getWidth(),getHeight(),this);
img_perso = ImageIO.read(new File("pinguin.png"));
g.drawImage(img_perso,coorX,coorY,this);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

public void deplacement(int MX,int MY){

while(coorX != MX && coorY != MY){
System.out.println("bonjour");
if (coorX < MX){
coorX++;
}
else if(coorX > MX){
coorX--;
}
if (coorY < MY){
coorY++;
}
else if(coorY > MY){
coorY--;
}
try{
Thread.sleep(6);
}catch (Exception e1){
e1.printStackTrace();
}
repaint();
}

}

public class Action implements MouseListener{
public void mouseRelased(MouseEvent e) {
int MX = e.getX();
int MY = e.getY();
deplacement(MX,MY);
}

@Override
public void mouseClicked(MouseEvent e) {
// TODO Auto-generated method stub

}

@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub

}

@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub

}

@Override
public void mousePressed(MouseEvent e) {
// TODO Auto-generated method stub

}

@Override
public void mouseReleased(MouseEvent e) {
// TODO Auto-generated method stub

}

}
}

updater.java:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;

public class Updater {
File code_source = new File("src/Fen.java");
File fichier = new File("fichier.txt");
PrintWriter ecrire;
String chaine ="";
String chaine2 ="";
public Updater(){
try {
InputStream is2 = new FileInputStream(code_source);
InputStreamReader ipsr2=new InputStreamReader(is2);
BufferedReader br2 =new BufferedReader(ipsr2);
String ligne;
while ((ligne=br2.readLine())!=null){
chaine+=ligne+"\n";
}
br2.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

try {
InputStream f = new FileInputStream(fichier);
InputStreamReader ipsr=new InputStreamReader(f);
BufferedReader br=new BufferedReader(ipsr);
String ligne;
while ((ligne=br.readLine())!=null){
chaine2+=ligne+"\n";
}
br.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

if (chaine == chaine2){
System.out.println("oui");
}else{

try {
ecrire = new PrintWriter(new BufferedWriter
(new FileWriter(fichier)));

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ecrire.print(chaine);
ecrire.close();
System.out.println("non");
}

}
}

Si vous trouvez le probleme dites le moi SVP.
