GameLogic

Il faut importer GameLogic dans Blender 2.5x alors qu'il était importer automatiquement dans la 2.49 import GameLogic

Adaptation

Blender 2.49 et python 2.6 donnait déjà des alertes dans la console sur les mèthodes obsolètes, si l'option du menu "Game" >> "Ignore Deprecation Warnings" n'est pas cochée. Si, comme moi, vous réutiliser du code trouvé de ci de là, il faut le corriger.
