我正在尝试为我的测试游戏测试一个随机数生成器，我一直在努力。目前设置为始终执行动作而不管生成的数字，并简单地说＆＃34; cheeeeeeeese＆＃34;在屏幕上，但我的问题是它通过鼠标或箭头键输入闪烁，但不会坚持。我不明白为什么它闪烁，只有在我输入的时候。

答案 0 :(得分：1)
你快乐你的文字＆＃34; cheeeeeeeese＆＃34; （程序中的变量L6）到显示表面D，更新它（调用pygame.display.update()），然后在此之后填充整个表面致电D.fill(MEXON)。
结果：每次一个事件发生时，文字会短暂闪烁，因为你＆＃34;清除＆＃34;在绘制文本后立即调用pygames fill()函数来显示屏幕。
您可以更改以解决问题：
删除事件循环中的pygame.display.update()行。
您不需要这样做，因为您在主游戏循环（pygame.display.flip()）中翻转（更新）显示器。
编写代码行
if G >= 0:
B(L6, (80, 150))
调用D.fill(MEXON)方法。
这可以解决你的闪烁问题。
