Aso hätt mir eigentlich auch selber aufallen müssen, ein Aufruf von repaint reicht in dem fall ja.
Dankeschön, aber du hast meine Frage noch nicht richtig beantwortet und ich habe die Antwort auf dieses Problem auch so noch nicht gefunden. Ich wollte statt dem Applet die Klasse Spiel aufrufen, auf der dann meine Schlange sich bewegt. Ungefär so nur dass hier nur das Spielfeld aufgerufen wird:
[code=Java]package PaketSnake;
import java.awt.*;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
//Damit das Applet einen Thread versteht, wird das Interface Runnable API: java.lang.Runnable implementiert.
public class Schlange extends Spiel implements Runnable
{
//Definiert die Anfangswerte, beginnt links oben
int px = 0;
int py = 50;
Thread wiederhole;// Objektname aufgabenbezogen
private boolean left = false;
private boolean right = true;
private boolean up = false;
private boolean down = false;
public void keyPressed (KeyEvent e)
{
int key = e.getKeyCode();
if (key==KeyEvent.VK_LEFT)
{
left = true;
right = false;
up = false;
down = false;
}
if (key==KeyEvent.VK_RIGHT)
{
right = true;
left= false;
up = false;
down = false;
}
if (key==KeyEvent.VK_UP)
{
up = true;
right = false;
left= false;
down = false;
}
if (key==KeyEvent.VK_DOWN)
{
down = true;
right = false;
left= false;
up = false;
}
}
public void start()
{//Thread erzeugen und starten
wiederhole = new Thread(this);
wiederhole.start();
}
//Innerhalb der run() Methode teile ich in einer Dauerschleife mit was zu wiederholen ist.
public void run(){//wiederhole
while(true)
{
if (right)
{
px++;//Wert aendern
try{ wiederhole.sleep(60);}//pausieren
catch(InterruptedException e){}
}
if (left)
{
px--;
try{ wiederhole.sleep(60);}//pausieren
catch(InterruptedException e){}
}
if (up)
{
py--;
try{ wiederhole.sleep(60);}//pausieren
catch(InterruptedException e){}
}
if (down)
{
py++;
try{ wiederhole.sleep(60);}//pausieren
catch(InterruptedException e){}
}
repaint();//neu zeichnen
}
}
public void paint(Graphics g)//zuerst Eigenschaft dann Objekt
{
/**
