Description:
-This program will simulate combate for a simple Role Playing Game (RPG).
- The game has a single type of character, the Fighter.
-Each inidividual Fighter has an integer value caled "hit points" that represents his/her current health (the amount of damage he/she can sustain before death)
-It will simulate combat between 2 Fighers.
-Combat is divided into rounds:
-During each round each combatant will make 1 attempt to stike the other.
-We will use random numbers to simulate rolling dice, the higher number attacks first, and the lower number goes 2nd if still alive.
-If there is a tie, the players will go at the same time, they will attack eachother at the same moment.
-During a simultaneous attack both Fighters will get to attack even if one (or both) if (are) killed during that round.
-The progam will use a random number to determine whether an attack attempt is successful or not.
-Each successful attack will inflict damage on the opponent.
-To simulate damage, we'll reduce the opponent's hit points by another random number
-When a Fighters hit points are reduced to 0 (or less than 0) that player is considered to be dead.
-Combat round continue until one(or both) combatants are dead.

我很难弄清楚如何调用我在课堂上创建的战斗机实例，这也是我的战斗功能，这是在课外。 我也想知道我是否正确比较了player1和player2的随机数。当搞乱它时，我尝试使用： player1 =战斗机（） player2 =战斗机（） 这样做我的错误消息会说Fighter（）＆gt;战斗机（）无法比拟。 最后，不太确定为什么我的test_attack失败了。
我的代码（到目前为止）：
import random
class Fighter:
def __init__(self, name):
'''
-This is my initializer method, which takes 2 parameters:
-Self
-Name (a string, the name of a fighter)
-This method will set a name attribute to the value of the name parameter
-It will also set a hit_points attribute to 10 (all fighters begin life with 10 hit points).
'''
self.name = name
self.hit_points = 10
def __repr__(self):
'''
-This method takes 1 parameter, self.
-It returns a string showing the name and hit points of the instances in the following format:
Bonzo (HP: 9)
'''
result = str(self.name) + " (HP: " + str(self.hit_points) + ")"
return result
def take_damage(self, damage_amount):
'''
-This method takes 2 parameters:
-self (the Fighter instance that calls the method)
-damage_amount (an integer representing the number of hit points of damage that have just been inflicted on this Fighter):
-The method should first decrease the hit_points attribute by the damage_amount.
-Next, it should check to see if the Fighter has died from the damage:
-A hit_points value that is 0 or less indicates death, and will print a message like the following:
\tAlas, Bonzo has fallen!
-Otherwise, it will print a message like the following (in this example, the player had 5 hit points left over after damage)
\tBonzo has 5 hit points remaining.
-The method returns nothing.
'''
self.hit_points = self.hit_points - damage_amount
if self.hit_points <= 0:
print('\t' + 'Alas, ' + str(self.name) + ' has fallen!')
else:
print('\t' + str(self.name) + ' has ' + str(self.hit_points) + ' hit points remaining.')
def attack(self, other):
'''
-This method takes 2 parameters:
-self
-other (another Fighter instance being attacked by self)
-The method will print the name of the attacker and attacked in the following format:
Bonzo attacks Chubs!
-Next, determine whether the attack hits by generating a random integer between 1 and 20
-Use the randrange function from the random module to get this number.
-A number that is 12 or higher indicates a hit:
- For an attack that hits, generate a random number between 1 and 6(using random.randrange) to represent the amount of damage inflicted by the attack
***Do NOT use the from random import randrange sytanze (randrange works like range, not like randint (think about the upper bounds you choose)).
- Print the amount of damage inflicted like the following:
\tHits for 4 hit points!
-Invoke the take_damage method on the victim (i.e. on other), passing it the amount of damage inflicted.
-For an attack that misses, print the following message:
\tMisses!
-This method returns nothing.
'''
self.other = Fighter(self.name)
print(str(self.name) + ' attacks ' + str(other) + '!')
attack = random.randrange(1, 20)

damage_amount = random.randrange(1, 6)
print('\t' + 'Hits for ' + str(damage_amount) + ' hit points!')
other.take_damage(damage_amount)
else:
print('\t' + 'Misses!')
def is_alive(self):
'''
-This method takes 1 parameter, self.
-It returns True if self has a positive number of points, False otherwise.
'''
if self.hit_points > 0:
return True
else:
return False
def combat_round(player1, player2):
'''
-This function takes 2 parameters:
-The 1st is an instance of Fighter.
-The 2nd is another instance of Fighter.
-It determines which of the 2 fighters attacks 1st for the round by generating a random interger (use randrange) between 1 and 6 for each fighter:
-if the numbers are equal:
-print the following message:
Simultaneous!
-Have each figher instance call his attack method on the other figher (the 1st figher in the argument list must attack first to make the test work correctly)
-if one number is larger:
-the fighter with the larger roll attacks 1st (by calling his attack method and passing it the figher being attacked).
-if the 2nd fighter survives the attack (call is_alive), he then attack the 1st.
-This function returns nothing.

答案 0 :(得分：1)
你上课看起来没问题，但combat_round函数有一些问题。
您使用player1 = Fighter()等进入了正确的轨道。
player1 = Fighter(name = 'Jeff')
player2 = Fighter(name = 'Bill')
但是现在你想先选择一个。您无法将它们与＆gt;，＆lt;，= =进行比较，而无需自定义__eq__()等特殊方法，因为Python不知道要比较哪个属性。如何设置属性然后比较它：
player1.speed = random.randrange(1,6)
player2.speed = random.randrange(1,6)
现在你可以编写这样的测试：
if player1.speed == player2.speed:
print("Simultaneous!")
此外，如果函数combat_round()使用战斗机的实例，那么您不需要在函数内实例化它们。但是，如果该函数接受了作为战士名字的字符串，那么你就会像我的例子一样。
