如何检测碰撞？ pygame
How to detect collision? pygame
我正在创建平台游戏并且有红色方块（他们应该杀了我）和白色方块（平台）
当我死了，我应该在当前水平的开始复活。
我做了碰撞检测，但它只有在我移动时才有效（当我跳到红色方块并且我没有按下任何东西时，它不起作用）
所以我真的很想知道如何更好地处理碰撞。
谢谢

您检查每个帧中每个事件与 killing_entities 列表的冲突。因此，如果事件队列中当前没有事件，则行：
if pygame.sprite.spritecollideany(player, killing_entities):
main()
永远不会执行。我猜你只想在主循环中使用该代码，而不是在事件处理循环中。
您的代码中还有一些奇怪的地方，例如
您没有操作QUIT event所以您无法关闭游戏window.
您使用相同的变量 running 作为主循环的条件并更改播放器的 xvel.
也无需更新显示两次（只需使用 pygame.display.flip()）。
您正在将一个巨大的 (3200x32px) 表面每帧传输到屏幕 1024 次。如果你想用黑色填充屏幕，只需每帧调用一次screen.fill('black')。
