It seem the init method of the source class also calls out another class. And the problem is, i can subclass the other class to with the required function but the end result is that it doesent work, since the source class cant accsess the subclass functions. > > The source code is pykkar. > > https://courses.cs.ut.ee/all/MTAT.03.100/2012_fall/uploads/opik/_downloads/pykkar.py > > I want to add it a new ability called left(). I cant manipulate the source class, cause then my comp will be the only one where the program runs. > > class pykkar_l(Pykkar): > def left(self): > self._world.execute("left") [...] You normally need to call the superclasses' __init__ method as well. Example: def __init__(self): Pykkar.__init__(self) ... any of your own init stuff ... Likewise for your world_l class. BTW, it is conventional to start class names with an upper case letters. Just style, but it helps other people when reading your code. Cheers, -- Cameron Simpson It looks like you've got Mister Bus Error installed. - tjc
