Ich möchte, dass mein Baby.class wächst zu einem Kind.class, weiß aber nicht, wie ich die grow Methode hier anwenden soll..

Ich hab es schon hiermit versucht: if (canSee(Wissenschaftler.class)) { getWorld().addObject(new Kind(), getX(), getY()); getWorld().removeObject(this); } da kommt es aber insofern zu Problemen, dass beim Ablauf des Szenarios in einer Error Meldung gesagt wird, der Actor würde sich nicht in der Welt befinden und 2., dass dann nicht ein Kind entsteht, sondern gleich massig viele.. Ich hoffe ihr könnt mir helfen :)

    }
I can't explain it in German, but you are trying to use your Maggie.class position (getOneObjectAtOffset) in meetMikrobe method after you have removeObject Maggie.

}
I condensed the code so it would not take so many lines (I had to properly indent the code anyway, so I could check the bracketing). You do not have to condense your code, but the addition of the 'return' statement is needed to prevent an IllegalStateException later in the code; and the 'meetMikrobe();' statement does nothing because you are not using what it returns for anything. I do not know if your program will do what you want after those changes. If is still doing the same thing, then the problem might be because of coding in another class. Also, post your issue again explaining what is happening and what you want and also post the pertinent code.
