【问题描述】：

我一直在尝试在我的 TextRPG 中添加陷阱

TypeError: init() 应该返回 None，而不是 'str'

错误来自这个。

 class TrapRoomTile(MapTile):
def __init__(self, x, y):
    r = random.randint(1,2)
    if r == 1:
        self.trap = items.PitFall()

        self.tripped_text = "The open hole of a Pit Fall trap obstructs the tunnel."

        self.set_text = "The floor in this hallway is unusually clean."

    else:
        return"""
        Looks like more bare stone...
        """
    super().__init__(x, y)

def modify_player(self,player):
    if not self.trap.is_tripped():
        player.hp = player.hp - self.items.damage
        print("You stumbled into a trap!")
        time.sleep(1)
        print("\nTrap does {} damage. You have {} HP remaining.".
              format(self.items.damage, player.hp))

def intro_text(self):
    text = self.tripped_text if self.items.is_tripped() else self.set_text
    time.sleep(0.1)
    return text

当我注释掉这段代码时，一切都会正常运行。我不知道该怎么办。生病发布到 github repo 的链接，代码在 world.py 从第 146 行开始。

【解决方案1】：

python 中的__init__ 方法只能用于初始化类变量。您正在从中返回一个字符串，您不应该这样做。

您可以删除 return 语句或将字符串设置为另一个变量。下面是一个你可以做的例子：

class TrapRoomTile(MapTile):
def __init__(self, x, y):
    r = random.randint(1,2)
    if r == 1:
        self.trap = items.PitFall()

        self.tripped_text = "The open hole of a Pit Fall trap obstructs the tunnel."

        self.set_text = "The floor in this hallway is unusually clean."

    else:
        self.set_text = "Looks like more bare stone..."
    super().__init__(x, y)

def modify_player(self,player):
    if not self.trap.is_tripped():
        player.hp = player.hp - self.items.damage
        print("You stumbled into a trap!")
        time.sleep(1)
        print("\nTrap does {} damage. You have {} HP remaining.".
              format(self.items.damage, player.hp))

def intro_text(self):
    text = self.tripped_text if self.trap.is_tripped() else self.set_text
    time.sleep(0.1)
    return text
