我试图让我的游戏对玩家有特殊的能力，但我遇到了一些问题。出于某种原因，user_health_active和user_health_display_active在到达第10轮后没有更新。我无法弄清楚为什么会这样，并且已经尝试了大约两个小时。从表面上看，不仅表面不会更新，而且实际的背景功能也不会。如果有人能为我提供一些有关为什么不起作用的见解，请告诉我。这是我的代码。

答案 0 :(得分：1)
修改您提到的变量的代码永远不会运行。这是相关的一点：
if game_level_score > 4:
user_teleport_active = True
user_teleport_display_active = ("True")
elif game_level_score > 9:
user_health_active = True
user_health_display_active = ("True")
因为您正在使用if和elif，所以只有在第一个块的条件为假时才会测试第二个块的条件。由于任何大于9的值也将大于4，因此第二个块将永远不会运行。
如果您希望独立测试这两个条件，则只需对两个条件使用普通if语句。如果您只想运行一个块，则需要将第一个条件扩展到4 < game_level_score <= 9，或者需要更改顺序，以便在> 9测试之前进行> 4测试。< / p>
