Sitze nun schon seit 1-2 Stunden davor und finde einfach den Fehler nicht!
Zu dem Problem: Die Schlange bewegt sich nach dem Starten nur in eine Richtung, dh. sobald ich die Schlange in eine andere Richtung steuern will, kommt diese Fehlermeldung:

Hoffe der ein oder andere Erfahrene kann kurz einen Blick drüber werfen.
Danke


EDIT:
Die Fehlermeldung kommt jetzt nicht mehr, da der Thread nur einmal, beim Starten, ausgeführt wird. Das andere Problem besteht trotzdem noch.
