Hallo zusammen, und ja ich weiss ich bin anfänger und bitte um entschuldigung.
Ich versuche gerade ein Game umzuschreiben da ich noch zuwenig ahnung habe um es selber auf die reihe zu bekommen. Der Code Stammt von einem rasperry.pi und es soll das Leiter (Laddder Game) geben. Ich stelle einfach mal mein code hier rein und hoffe das mir jemand ein wnig helfen kann, ohne mich gleich zu steinigen.
Ich danke euch schon mal im vorraus.
P.S Es ist noch kein Meister vom Himmel gefallen.
