Controles Pong Com KeyListener
Eu tive um pouco de dificuldade para fazer o meu jogo de pong funcionar, este projeto começou simplesmente com fazer uma bola ter física, mas então eu decidi fazer um pouco mais de trabalho
Eu tenho aquela bola quicando para frente e para trás e todas, exceto as teclas W e S, não controlarão o jogador 1 e as teclas de seta para cima e para baixo não controlam o jogador 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();
}
Não vai mesmo mostrar as mensagens de impressão do sistema
Eu não sei se é só essa parte do código que é o problema ou se está em outro lugar
Se estiver em outro lugar, aqui está o link para o resto deste arquivohttp://pastebin.com/TJbLBxL7

Meu novo código O problema com este é que apenas um jogador pode ser controlado de cada vez
Ele também tem a minha tentativa tola de consertá-lo, fazendo 2 MyKeyAction, mas não mudou nada
