pygame - 如何使我的变量在我单击 pygame 中的按钮时仅增加一个，以及如何使文本更新

Question

我正在尝试使用 pygame 为学校制作一个空闲的 Clicker 游戏，我遇到了一些问题，我真的很感谢一些帮助

我的程序需要一些帮助，主要是我有两个问题，一个是当我单击“升级磨刀石按钮”时，当变量磨刀石级别上升时，文本不会，并且由于我这样做的方式，我不能只是 blit一些文本在屏幕上，所以我需要一些帮助，其次，当我按下升级按钮并将其打印在屏幕上时，变量 Whetstone Level 上升不止一个，我希望它上升一个级别点击，所以我想知道我能做些什么来改变它，让它只上升一级

提前致谢

您可以使用 pygame.MOUSEBUTTONDOWN 来注册每次按下鼠标按钮的一次鼠标单击。在您的情况下，您可以使用您的mouse_click按钮变量。将事件循环移到所有 if 语句之前。

    mouse_click = False
    for event in pygame.event.get():
        if(event.type == pygame.QUIT):
            done = True
        if event.type == pygame.MOUSEBUTTONDOWN:
            mouse_click = True  

    if menuScreen.checkUpdate():
         #...

这也意味着您的foucsCheck成员函数应该返回mouseclick而不是它的下标。

def focusCheck(self, mousepos, mouseclick):
     if(mousepos[0] >= self.x and mousepos[0] <= self.x + self.sx and mousepos[1] >= self.y and mousepos[1] <= self.y + self.sy):
         self.current = True
          return mouseclick #mouseclick[0]

这解决了注册单击的问题。

对于第二个问题，最好只更改文本，但由于您的按钮类不允许这样做，您可以在 Whetstone_Level每次单击时使用更新的变量重新创建按钮。话虽如此，我建议您稍微修改您的课程以促进这一点。

if clickdamageupgrade.focusCheck(mouse_pos, mouse_click):
      clickdamagelevel = Button(160, 10, 150, 50, colours["Black"], colours["Red"], "arial", 15, colours["White"], str(Whetstone_Level))
