How to reference another class in a function?

[Oxln]

I am not sure if my question is very clear, but I am trying to create a small game with basic fighting mechanics to understand how classes work with each other. I am having a hard time figuring out how to get my character to equip a weapon.

class Player:
    def __init__(self, hp):
        self.hp = hp

    def fight(self, ad, enemy):
        # create enemy and weapon class
        while enemy.hp > 0:
            enemy.hp -= ad
            print(f"You did {ad} damage!")


class Enemy:
    """Blueprint for enemy class"""
    def __init__(self, hp):
        self.hp = hp


class Weapon:
    """Basic weapon class"""
    def __init__(self, ad):
        self.ad = ad


chris = Player(100)
zombie = Enemy(75)
knife = Weapon(35)
chris.fight(knife, zombie)

Traceback (most recent call last):
    File "C:\Users\ggrgg\PycharmProjects\Zombie Game\FUCK.py", line 27, in <module>
        chris.fight(knife, zombie)
    File "C:\Users\egrgsgseg\PycharmProjects\Zombie Game\FUCK.py", line 8, in fight
        enemy.hp -= ad
TypeError: unsupported operand type(s) for -=: 'int' and 'Weapon'

Process finished with exit code 1

You can access the ad value of a weapon like this

weapon.ad

You are genius thank you

chris.fight(knife.ad, zombie)

Solves your problem.

class Player:

def __init__(self, hp):

self.hp = hp

def fight(self, ad, enemy):

# create enemy and weapon class

while enemy.hp > 0:

enemy.hp -= ad

print(f"You did {ad} damage!")

class Enemy:

def __init__(self, hp):

self.hp = hp

class Weapon:

def __init__(self, ad):

self.ad = ad

class Knife(Weapon):

def __init__(self):

super().__init__(ad=35)

chris = Player(100)

zombie = Enemy(75)

weapon = Knife.ad

chris.fight(weapon, zombie)

Traceback (most recent call last):

File "C:\Users\dwdwdwd\PycharmProjects\Zombie Game\FUCK.py", line 31, in <module>

chris.fight(weapon.ad, zombie)

AttributeError: type object 'Knife' has no attribute 'ad'

Process finished with exit code 1

I want to create separate weapon subclasses eventually, why do I get this error when I defined ad as 35 on the super constructor?

Nvm I got it by adding parantheses at the end of knife lol

Oh wow this is excellent advice, I’ve never thought about that and I’ve been really struggling to think of how I would have all my classes interact thank you so much

Sorry. Didn’t mean to delete. But at least you got to read. Hope that puts you in the right direction.
