我正在尝试创建一个Hangman-ish游戏，我注意到screen.blit发生了一些奇怪的事情。
在“加拿大”一词中，有三个A.我已经成功创建了一个包含所有字母表字母的列表，当我点击“C”时，它实际上将“C”转移到它的指定位置。但是，当您单击“A”时，只显示第一个“A”。
这是我的代码：

绝对一切都有效，但是'A'问题。
帮助！
答案 0 :(得分：0)
我没有使用PyGame，但看着你的程序，看起来就是这样：
screen.fill((255, 255, 255))）因此，您可以看到＆＃39; A将被暂时绘制，但随后会在第3部分和第4部分中删除。如果您需要在每次迭代中清除屏幕，那么您需要跟踪例如，通过将它们添加到列表中来保持绘图的对象。
答案 1 :(得分：0)
我在屏幕上点了一个单独的A，有不同的位置。它的原始位置在屏幕之外，并在按下“A”时弹出正确的代码行。
