Я вижу две проблемы.Во-первых, вы передаете имя переменной вместо самой переменной.
измените это:
while alpha.hp>0 and beta.hp>0:
while turn==True:
opposite="beta"
current="alpha"
action=raw_input("attack, sleep, eat or shed? ")
try:
if action=="attack":
alpha.attack(opposite, current)
на следующее:
while alpha.hp>0 and beta.hp>0:
while turn==True:
opposite=beta
current=alpha
action=raw_input("attack, sleep, eat or shed? ")
try:
if action=="attack":
alpha.attack(opposite, current)
Дополнительно,у вас есть поле атаки, определенное дважды в классе Snake.
class Snake:
attack=25
def attack(self, opposite, current):
Вот что я придумал после игры с вашим кодом:
import random
class Snake:
hp=100
attack_skill=25
defense=1
def set_name(self, name):
self.name=name
def shed(self):
self.defense=self.defense+1
def attack(self, opposite):
opposite.hp = opposite.hp - (self.attack_skill - opposite.defense)
def eat(self):
self.attack_skill += 5
print(str(self.name) + " eats a rat!")
print(str(self.name) + "'s attack dmg is now " + str(self.attack_skill))
def sleep(self):
print (str(self.name) + " goes to sleep")
self.hp=self.hp+10
if self.hp>100:
self.hp=100
print (str(self.name) + " wakes up with " + str(self.hp) + "hp")
##initialises the snakes
alpha=Snake()
beta=Snake()
## gives the snakes names of the user's choice
alpha_name=raw_input("What would you like to name your snake? ")
alpha.set_name(alpha_name)
beta_name=raw_input("What would you like to name the other snake? ")
beta.set_name(beta_name)
##starts the game
turn=True
while alpha.hp>0 and beta.hp>0:
while turn==True:
opposite="beta"
current="alpha"
action=raw_input("attack, sleep, eat or shed? ")
try:
if action=="attack":
alpha.attack(beta)
if action=="sleep":
alpha.sleep()
if action=="eat":
alpha.eat()
if action=="shed":
alpha.shed()
turn=False
except IOError:
print("Please chose only one action, exaclty how it is typed")
while turn==False:
opposite="alpha"
current="beta"
if beta.hp<15:
beta.sleep()
elif alpha.hp>75:
beta.attack(alpha)
else:
index=random.randint(1, 3)
if index==1:
beta.shed()
elif index==2:
beta.eat()
else:
beta.attack(alpha)
turn=True
