Java und Processing PingPong Spiele Modellierung !

Hallo Liebe Community,

Ich stelle euch heute mein Programm Modell von dem bekannten Spiel Ping-Pong vor.
Da es sich nur um ein Modell handelt habe ich die Hilfe von Processing in Anspruch genommen.
Ich w�rde gerne mit euch zusammen weiter daran Arbeiten um den Thread immer mehr zu verfeinern.

Als erstes solltet ihr �ber processing.org die Software "Processing" donwloaden.
Eigentlich braucht man nur die "core.jar" Datei, falls man in Java programmieren will,
aber ich Empfehle euch die Software sehr.

Um euch einen kleinen einblick �ber die Software zu geben folgt der Text welcher beim downloaden erscheint.
"Processing is open source, free software. All donations fund the Processing Foundation,
a nonprofit organization devoted to advancing the role of programming within the visual arts through developing Processing."

Es wird empfohlen die Java JDK �ber Oracel zu downloaden und zu Installieren.
Vergesst nicht die ensprechenden Umgebungsvariablen zu setzten.

!!Falls ihr keine Erfahrung mit Java habt �berspringt den ersten Teil.!!

Teil 1
Processing und Java

Um den Code zum laufen zu bringen m�sst ihr in eurem processing Ordner den folgenden
Pfad folgen \Processing\core\library\core.jar und die "core.jar" Datei implementieren.

Achtung:
Dies ist nur ein Modell und kein code welches kommerziell zu gebrauchen ist.
Bedenkt das hier nicht Objektorientiert programmiert wurde also bitte keine Annmerkungen darauf.
