def input(self): if not self.attacking: keys = pygame.key.get_pressed()#检测键盘是否有输入 #键盘up or down 改变y轴的值 if keys[pygame.K_UP]: self.direction.y = -1 self.status = 'up' elif keys[pygame.K_DOWN]: self.direction.y = 1 self.status = 'down' else: self.direction.y = 0 #键盘左右键改变x轴的值 if keys[pygame.K_RIGHT]: self.direction.x = 1 self.status = 'right' elif keys[pygame.K_LEFT]: self.direction.x = -1 self.status = 'left' else: self.direction.x = 0 # 攻击键为空格 if keys[pygame.K_SPACE]: self.attacking = True self.attack_time = pygame.time.get_ticks() self.create_attack() self.weapon_attack_sound.play() # 魔法攻击使用左边Shift键 if keys[pygame.K_LSHIFT]: self.attacking = True self.attack_time = pygame.time.get_ticks() style = list(magic_data.keys())[self.magic_index] strength = list(magic_data.values())[self.magic_index]['strength'] + self.stats['magic'] cost = list(magic_data.values())[self.magic_index]['cost'] self.create_magic(style,strength,cost) #键盘Q键切换武器 if keys[pygame.K_q] and self.can_switch_weapon: self.can_switch_weapon = False self.weapon_switch_time = pygame.time.get_ticks() if self.weapon_index < len(list(weapon_data.keys())) - 1: self.weapon_index += 1 else: self.weapon_index = 0 self.weapon = list(weapon_data.keys())[self.weapon_index] #键盘E键切换魔法道具 if keys[pygame.K_e] and self.can_switch_magic: self.can_switch_magic = False self.magic_switch_time = pygame.time.get_ticks() if self.magic_index < len(list(magic_data.keys())) - 1: self.magic_index += 1 else: self.magic_index = 0 self.magic = list(magic_data.keys())[self.magic_index]

这段代码是角色控制的输入函数，用于检测玩家在键盘上的输入，并根据输入改变角色的状态。如果玩家按下向上或向下箭头键，则角色的y轴方向分别变为-1或1，并相应地设置角色的状态为up或down；如果按下向左或向右箭头键，则角色的x轴方向分别变为-1或1，并相应地设置角色的状态为left或right；如果按下空格键，则角色开始攻击，并播放相应的音效；如果按下左边Shift键，则角色使用魔法攻击；如果按下Q键，则角色切换武器；如果按下E键，则角色切换魔法道具。

这段代码是一个Python中的类的初始化方法（即构造函数）。下面是对每一行代码的注释说明：

def __init__(self, pos, groups, obstacle_sprites, create_attack, destroy_attack, create_magic):
    super().__init__(groups)  # 调用父类的构造函数
    self.image = pygame.image.load('../graphics/test/player.png').convert_alpha()  # 加载图像
    self.rect = self.image.get_rect(topleft=pos)  # 获取图像的矩形区域并设置位置
    self.hitbox = self.rect.inflate(-6, HITBOX_OFFSET['player'])  # 设置碰撞区域

    self.status = 'down'  # 设置状态为向下
    self.attacking = False  # 设置攻击状态为False
    self.attack_cooldown = 400  # 设置攻击冷却时间为400毫秒
    self.attack_time = None  # 初始化攻击时间为None
    self.obstacle_sprites = obstacle_sprites  # 设置障碍物精灵组
    self.create_attack = create_attack  # 设置创建攻击的方法
    self.destroy_attack = destroy_attack  # 设置销毁攻击的方法
    self.create_magic = create_magic  # 设置创建魔法的方法
    self.weapon_index = 0  # 初始化武器索引为0
    self.weapon = list(weapon_data.keys())[self.weapon_index]  # 获取武器名称
    self.can_switch_weapon = True  # 设置能否切换武器状态为True
    self.weapon_switch_time = None  # 初始化切换武器时间为None
    self.switch_duration_cooldown = 200  # 设置切换武器的冷却时间为200毫秒
    self.magic_index = 0  # 初始化魔法索引为0
    self.magic = list(magic_data.keys())[self.magic_index]  # 获取魔法名称
    self.can_switch_magic = True  # 设置能否切换魔法状态为True
    self.magic_switch_time = None  # 初始化切换魔法时间为None
    self.stats = {'health': 100, 'energy': 60, 'attack': 10, 'magic': 4, 'speed': 5}  # 初始化属性值
    self.max_stats = {'health': 300, 'energy': 140, 'attack': 20, 'magic': 10, 'speed': 10}  # 设置最大属性值
    self.upgrade_cost = {'health': 100, 'energy': 100, 'attack': 100, 'magic': 100, 'speed': 100}  # 设置升级属性所需成本
    self.health = self.stats['health'] * 0.5  # 初始化生命值
    self.energy = self.stats['energy'] * 0.8  # 初始化能量值
    self.exp = 5000  # 初始化经验值
    self.speed = self.stats['speed']  # 初始化速度值
    self.vulnerable = True  # 设置受伤状态为True
    self.hurt_time = None  # 初始化受伤时间为None
    self.invulnerability_duration = 500  # 设置无敌时间为500毫秒
    self.weapon_attack_sound = pygame.mixer.Sound('../audio/sword.wav')  # 导入武器攻击音效
    self.weapon_attack_sound.set_volume(0.4)  # 设置音量为0.4

该类的实例化会在游戏中创建一个玩家对象，并包含了玩家的各项属性和方法。

任务描述 本关任务：编写一个能实现游戏角色变身的小程序。 相关知识 为了完成本关任务，你需要掌握：1.如何定义抽象类（接口），2.如何使用抽象类。 题目内容 已知游戏中常见人物状态State抽象类，包括站立（Idle），行走（Run），攻击(Attack)，死亡(Dead)等动作。在游戏中有角色hero类，拥有人物状态同时还拥有血量，攻击力，防御力等属性,有怪物类Monster,怪物有血量，攻击力，防御力，怪物类型等属性。 已知角色可以变身为怪物，现在main函数中，模拟某个角色在正常情况下以及在变身状态下的各种状态操作(输入1为正常hero，输入2则变身为monster)。要求，使用抽象类及的基类指针实现。 编程要求 根据提示，在右侧编辑器补充代码，完成程序。 测试说明 平台会对你编写的代码进行测试： 测试输入： 1 预期输出： hero is idleling... hero is attack... hero is running... hero is dead... 测试输入： 2 预期输出： Monster is idleling... Monster is attack... Monster is running... Monster is dead... 开始你的任务吧，祝你成功！
