I've finally figured out the basics of OOP; I've created a basic character
creation class for my game and it works reasonably well. Now that I'm
trying to build a subclass that has methods to determine the rank of a
character but I keep getting errors.
I want to "redefine" some attributes from the base class so I can use them
to help determine the rank. However, I get the error that my base class
doesn't have the dictionary that I want to use. I've tried several things
to correct it but they don't work (the base class is called "Character"
and the subclass is called "Marine"):
*explicitly naming the Marine's attribute self.intel =
Character.attrib_dict["intel"]
*adding Character.__init__(self) to the Marine's __init__(self) method
*changing the self.intel attribute from referencing the Character's
dictionary to self (based on the assumption that since Marine is a
subset of Character, it should have it's own attrib_dict being created
Nothing seems to work; I still get the error "class Character has no
attribute "attrib_dict".
I can't see why it's saying this because Character.__init__(self) not only
has self.attrib_dict = {} but it also calls the setAttribute method
explicitly for each attribute name. If I do a print out of the dictionary
just for Character, the attributes are listed.
Without a sample of your code and the actual tracebacks you're getting
it is difficult to know what's going wrong.
Are you writing your class like this:
class Character:
def __init__(self):
# do some stuff here..
class Marine(Character):
def __init__(self):
Character.__init__(self)
# do some stuff here..
?
Peace,
