TrapRoomTile 沒有屬性陷阱？

Question

我的 TrapRoomTile 現在拋出一個錯誤 TrapRoomTile has no attribute trap。 我聲明 self.trap = items.Pitfall() 它的寫法與我的 Enemy 瓷磚的寫法完全相同，但我不斷收到錯誤消息。 我想我正在俯瞰像往常一樣小的東西，所以任何幫助將不勝感激

你只是偶爾制造陷阱。 50% 的情況下，您根本不會將該屬性放入 TrapRoomTile：

r = random.randint(1,2)
if r == 1:
    self.trap = items.PitFall() 

你可以把self.trap = None放在else那里，如果你真的想要沒有陷阱的陷阱瓷磚。 然后你需要在嘗試使用它時檢查陷阱瓷磚是否有陷阱。

也可能是基於組件的方法而不是子類化會更好地為您服務，但那是另一回事。
