Class has no attribute X

Question

I've been working on making a combat test for a RPG game. For whatever reason I am getting a class has no attribute error.

Any ideas how to fix this?

class Enemy:
 def __init__(self, name, H, STR):
 self.name = name
 self.H = H
 self.STR = STR
 def is_alive(self):
 return self.H > 0
 enemyturn = ["1", "2"]
class Goblin(Enemy):
 def __init__(self, name, H, STR):
 name = "Goblin"
 H = 50
 STR = 5

These classes are used in the code below:

if command == "1":
 Goblin.H -= Player.STR
 print("You strike the Goblin for {0} damage.".format(Player.STR))
 random.choice(enemyturn)
 if random.choice == "1":
 Player.H -= Goblin.STR
 print("The Goblin strikes you for {0} damage.".format(Player.STR))
 if random.choice == "2":
 pass
 Combat()

• Marcin: Which line returns this error?
• Jivan: @Marcin this one: Goblin.H -= Player.STR

Answer 1

You are calling your attributes before the objects are instantiated.

You should declare them as class variables.

class Enemy:
 name = ""
 H = 0
 STR = 0
 def __init__(self, name, H, STR):
 self.name = name
 self.H = H
 self.STR = STR
 def is_alive(self):
 return self.H > 0
class Goblin(Enemy):
 def __init__(self, name, H, STR):
 self.name = "Goblin"
 self.H = 50
 self.STR = 5
