python rpg游戏代码

以下是一个简单的Python RPG游戏代码示例：

import random

class Player:
    def __init__(self, name, health, attack, defense):
        self.name = name
        self.health = health
        self.attack = attack
        self.defense = defense
    
    def attack_enemy(self, enemy):
        damage = self.attack - enemy.defense
        if damage > 0:
            enemy.health -= damage
            print(f"{self.name} did {damage} damage to {enemy.name}.")
        else:
            print(f"{self.name} did no damage to {enemy.name}.")
    
    def is_alive(self):
        return self.health > 0

class Enemy:
    def __init__(self, name, health, attack, defense):
        self.name = name
        self.health = health
        self.attack = attack
        self.defense = defense
    
    def attack_player(self, player):
        damage = self.attack - player.defense
        if damage > 0:
            player.health -= damage
            print(f"{self.name} did {damage} damage to {player.name}.")
        else:
            print(f"{self.name} did no damage to {player.name}.")
    
    def is_alive(self):
        return self.health > 0

        self.player = Player("Player", 100, 20, 10)
        self.enemies = [
            Enemy("Goblin", 50, 10, 5),

            while enemy.is_alive() and self.player.is_alive():
                print(f"{self.player.name} (Health: {self.player.health})")
                print(f"{enemy.name} (Health: {enemy.health})")
                print("What do you want to do?")
                print("1. Attack enemy")
                print("2. Run away")
                choice = input("Enter your choice (1 or 2): ")
                if choice == "1":
                    self.player.attack_enemy(enemy)
                elif choice == "2":

                if enemy.is_alive():
                    enemy.attack_player(self.player)

                print(f"You defeated the {enemy.name}!")
                self.enemies.remove(enemy)
        
        if not self.enemies:
            print("Congratulations! You have defeated all the enemies and won the game!")
        else:
            print("Game over. You have been defeated by an enemy.")

game = Game()
game.start()

这个游戏有一个玩家和多个敌人。玩家和敌人都有名字、生命值、攻击力和防御力。玩家可以选择攻击敌人或逃跑。如果玩家选择攻击，他们会造成攻击力减去敌人防御力的伤害。如果玩家选择逃跑，游戏将结束。如果敌人死亡，它将从可用敌人列表中删除。如果所有敌人都被击败，玩家就赢了游戏。
