我正在制作一个吃 bean 人游戏，目前我已经具备了基础知识，但我无法让吃 bean 人颗粒在全部被吃掉后重生。目前，我已设置为在吃完 pac 颗粒后，它将从 pacpellets 列表中删除。当列表为空时，它会被重新填充，然后被告知将所有 pac 颗粒重新绘制到屏幕上。它检查了所有正确的函数和所有内容，我已经用 print 语句检查过，但是 pygame.draw.rect 不起作用，我不明白为什么。

最佳答案
我会做这样的事情:定义一个函数，创建一个 Sprite 组并用颗粒 Sprite 填充它，然后返回它并将其分配给主函数中的变量。当pellets组为空时，只需再次调用此函数并将新组分配给旧变量，颗粒就会再次出现。
