Question

我有一个我正在进行的游戏，并且每次到达一百个地方时都试图提高等级，即100,200,300等等。

这是我的功能，这可能是我忘记做的非常简单

感谢@redunderthebed，我发现该函数位于__init__()，而且它没有进入if语句。所以我将我的关卡更改为if循环。所以我把它移到我的main()方法中，当得分变为100时，它仍然没有进入if循环。我在这里做错了什么？

我找不到Livewires的任何真实文档，但我会根据你的代码说（并假设它正在做任何事情）你需要在这里进行等级检查：

def update(self):
    """ move to mouse x position """
    self.x = games.mouse.x

    if self.left < 0:
        self.left = 0

    if self.right > games.screen.width:
        self.right = games.screen.width

    self.check_catch()
    self.check_level()

也许check_level()

def check_level(self):
    if not self.score.value % 100:
        self.level += 1
        self.level_msg = games.Message(value="LEVEL {}"
                                       .format(the_pan.level),
                                       size=90,
                                       color=color.red,
                                       x=games.screen.width / 2,
                                       y=games.screen.height / 2,
                                       lifetime=5 * games.screen.fps,
                                       after_death=None)
    games.screen.add(the_pan.level_msg)

当分数达到数百个位置时提高等级
