Question

我一直试图在我的TextRPG中添加陷阱，我认为有些东西可以进行一些调试，但是遇到的第一个错误是

。

TypeError： init （）应该返回None，而不是'str'

错误源于此。

 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，一切都会按预期运行。我对此无所适从。不适用于发布指向github存储库的链接，代码在world.py中，从第146行开始。

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

您可以删除return语句或将字符串设置为另一个变量。这是您可能会执行的操作的示例：

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
