Ok,...I failed. Nevertheless I got something playable, but there is not much gameplay and some bugs with the grandma.

You can use the gaming console if you want:
e.g.
Oma.forcedJump(2f);
Oma.moveRelAndPlay(2f);
Oma.moveToAndPlay(2f);
Oma.stop();
same for Player.
Actually it took me too much time to write unnecessary code. Actually I created or went on creating something like a game engine that makes it possible for me to create most of the stuff without java. Only designing the world in blender and injecting logic with a scripting language.
I worked hard to finish something and when I wanted to release it I made a stupid mistake with outcommenting lines. And I was too braindead at the moment to fix it :D
where is the difference?
if (a==true)
System.out.println("aaa");
doCoolstuff;
and
if (a==true)
//System.out.println("aaa");
doCoolstuff
