Kontrola Pong Z KeyListener
Wpadłem na trochę kłopotów z uruchomieniem gry pong, ten projekt zaczął się od zrobienia piłki z fizyką, ale potem postanowiłem zrobić więcej pracy
Mam tę piłkę odbijaną tam iz powrotem i wszystkie oprócz klawiszy W i S nie kontrolują odtwarzacza, a klawisze strzałek w górę iw dół nie kontrolują odtwarzacza 2
public void keyPressed(KeyEvent e){
if(e.getKeyCode() == e.VK_UP){
p2Y -= 3;
System.out.println("UP");
}
if(e.getKeyCode() == e.VK_DOWN){
p2Y += 3;
System.out.println("Down");
}
if(e.getKeyCode() == e.VK_W){
p1Y -= 3;
System.out.println("Up");
}
if(e.getKeyCode() == e.VK_S){
p1Y += 3;
System.out.println("down");
}
repaint();
}
Nie będzie nawet wyświetlać komunikatów drukowania systemu
Nie wiem, czy to tylko ta część kodu, która jest problemem, czy też jest gdzieś indziej
Jeśli jest gdzieś indziej, jest link do reszty tego plikuhttp://pastebin.com/TJbLBxL7

Mój nowy kod Problemem w tym jest to, że tylko jeden gracz może być kontrolowany naraz
Ma też moją głupią próbę naprawienia tego poprzez wykonanie 2 MyKeyAction, ale wcale tego nie zmieniło
