Как добавить несколько уровней карты плиток в Pygame?

Question

Я работаю над игрой на основе тайлов. Я уже создал 3 уровня для игры, но теперь я не знаю, как загрузить новые уровни в игре. Игра начинается на уровне 1, и после обработки всех мобов она начинает уровень 2, но после обработки всех мобов на уровне 2 она не загружает уровень 3. Вместо этого она перезапускается на уровне 2. Я думаю, что моя ошибка в обновлении раздел кода, но так как я все еще очень неопытен, это может быть больше, чем просто «одна» ошибка в этом коде. Я был бы рад, если бы кто-нибудь мог помочь мне

вот мой main.py кода:

Answer 1

[...] после обработки всех мобов на уровне 2 он не будет загружать уровень 3. Вместо этого он перезапускается на уровне 2. Я думаю, что моя ошибка в разделе обновления кода, [.. .]

Конечно. См. Следующие удержания кода:

   def update(self):
       # Game over?
       if len(self.mobs) == 0:
           self.new_2()
           if len(self.mobs) == 0:
               self.new_3()

self.new_3() никогда не будет вызываться. Если len(self.mobs) == 0 выполнено, self.new_2() выполняется и self.mobs инициализируется.

Добавьте номер уровня (self.current_level) к классу Game. Увеличьте уровень в update и вызовите либо new_2, либо new_3 в зависимости от self.current_level. Например:

class Game:
    def __init__(self):
        # [...]
        self.current_level = 1

    # [...]

    def update(self):
        # Game over?
        if len(self.mobs) == 0:
            self.current_level += 1
            if self.current_level == 2:
                self.new_2()
            else:
                self.new_3()

При таком подходе легко добавлять и загружать дополнительные уровни.
