Question

我正在用python和pygame制作游戏，因为我的游戏涉及很多精灵，所以我决定为每个敌人\角色使用一个单独的线程，它运行一个方法_mainloop。我刚刚开始这个，我遇到了一个问题。我正在制作一个绘制火柴人的基础课程，并且具有到目前为止能够在X坐标上编写的能力。它几乎完美地运行，但问题是我认为，因为火柴人是在类_mainloop方法中绘制的，并且显示器正在主事件处理循环中更新，这使得火柴人看起来有时候会更厚，这有点奇怪。我不想更新_mainloop中的显示，因为屏幕上会有大约FPS *敌人+玩家，这可能会达到每秒约500 pygame.display.updates，这有点过分。如果有人知道有更好的方法可以做到这一点，你能告诉我吗？好吗？
