Question

因此，当我和我的熟人在pygame中工作时，我们遇到了一个问题：每次进度条超过100时，它就会崩溃并向我们显示错误。错误代码为：

 "Traceback (most recent call last):
  File "C:/Users/Tip/Documents/loading bar/load.py", line 150, in <module>
    loading(progress/2)
  File "C:/Users/Tip/Documents/loading bar/load.py", line 60, in loading
    screen.blit(text, (300, 100))
TypeError: argument 1 must be pygame.Surface, not str
libpng warning: iCCP: known incorrect sRGB profile".

还有帮助，这是代码：

    if progress/2 >= 100:
        progress = 200

    loading(progress/2)
    pygame.display.flip()

我们的代码应该是一个加载栏。显示进度问题的文本在加载x％部分中。请帮忙，谢谢。

Answer 2

在loading函数中，如果进度为> = 100，则text是字符串，如果进度为<100，则pygame.Surface是字符串。

由于pygame.Surface.blit方法仅将pygame.Surface作为第一个参数，因此在传递字符串时将引发TypeError。

一个简单的解决方法是在if子句中屏蔽text表面：

def loading(progress):
    if progress < 100:
        text = font.render("loading: " + str(int(progress)) + "%", True, green)
        screen.blit(text, (300, 100))

您还可以为透明表面涂色或进行text = font.render("", True, green)，但这将毫无意义。只要进度> = 100，就不要涂任何东西。
