Pong Controls Mit KeyListener
Ich habe ein bisschen Probleme damit, mein Pong-Spiel zum Laufen zu bringen. Dieses Projekt begann einfach damit, einen Ball physikalisch zu machen, aber dann habe ich beschlossen, etwas mehr zu arbeiten
Ich habe diesen Ball hin und her springen und alle Tasten außer den Tasten W und S steuern nicht Spieler 1 und die Pfeiltasten nach oben und unten steuern nicht Spieler 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();
}
Es werden nicht einmal die Systemdruckmeldungen angezeigt
Ich weiß nicht, ob es nur dieser Teil des Codes ist, der das Problem ist, oder ob es woanders ist
Wenn es sich um einen anderen Ort handelt, finden Sie hier den Link zum Rest dieser Dateihttp://pastebin.com/TJbLBxL7

Mein neuer Code Das Problem mit diesem Code ist, dass immer nur ein Spieler gleichzeitig gesteuert werden kann
Es hat auch meinen törichten Versuch, es zu beheben, indem ich 2 MyKeyAction mache, aber es hat es überhaupt nicht geändert
