Hallo zusammen,
ich programmier grad das Spiel Breakout (Arkanoid) und bleib bei einer Fehlermeldung stecken. Kann mir jemand helfen? Wäre total nett. Hier sind die Codes:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
public class Notarkanoid{
/**
* @param args
*/
private Ball ball;
public Notarkanoid() {
ball = new Ball(this);
}
public static void main(String[] args){
Notarkanoid notarkanoid = new Notarkanoid();
}
}

{
super();
bat = new Bat();
this.x = bat.x+bat.w+10; // control the start point of x
this.y = bat.y+(bat.l/2); // control the start point of y
this.d = 20; // control the size of the ball
this.dx = 5; // control the speed of x
this.dy = 5; // control the speed of y
for (int i = 0; i < size; i++) {
