为什么我在尝试向我的 textRPG 添加陷阱时遇到此错误

Question

我一直在尝试将陷阱添加到我的 TextRPG 我有一些东西我认为可以通过一些调试工作但是我运行遇到的第一个错误是。

TypeError: init() 应该 return None，而不是 'str'

错误由此而来。

 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，一切都按预期运行。我不知道该怎么做。 ill post link 到 github 代码库 world.py 从第 146 行开始。

python中的__init__方法只能用于初始化class变量。您正在 return 从中提取一个字符串，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。以下是您可能可以执行的操作的示例：

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
