Pygame文件未加载

Question

我最近完成了一个俄罗斯方块游戏，没有我能看到的错误。当我在文本编辑器（Sublime）中运行它时，它可以很好地运行，并且没有填充错误。

但是，如果我尝试在桌面上的文件本身中运行它，它将仅加载开始菜单屏幕，而不会加载主游戏屏幕本身，并在此之后退出Python程序。在该程序关闭之前，我看不到Python的任何错误。我的代码与主俄罗斯方面的屏幕有问题吗？我觉得我缺少一些东西，但似乎无法说明它是什么。我是编码的全新，并认为这将是一件有趣的事情，可以让我的同事作为礼物感到惊讶。谢谢你！

还有另一个文件可以保存高分：

def update_score(nscore):
    score = max_score()

    with open('scores.txt', 'w') as f:

            f.write(str(score))
        else:

def max_score():
    with open('scores.txt', 'r') as f:
        lines = f.readlines()
        score = lines[0].strip()

    return score

Answer 1

我有点犹豫地写答案，以代替仅发表评论。但是，我想分享我将您的程序复制到测试系统上的文本文件并运行程序。程序无法正常工作的唯一方法是，如果未找到文本文件或文本文件没有分数值。否则，它运行良好。这是执行程序的快照。

我不知道您正在运行哪种版本的Python或正在运行的操作系统，但是以下是我的系统和版本Python的规格：

• OS：Linux Mint版本20.3（una）
• Python版本：3.8.10
• PyGame版本：2.1.2，

因此我的建议将是：

• 检查您的PyGame和Python版本，
• 并确保您的文本文件已保存而且它具有一个数字分数值，

我不知道您的文本编辑器的特征，但是您可能会尝试另一个文本编辑器（例如“记事本++”，可用于各种操作系统）。

希望有帮助。

问候。
