python - 为什么 Pygame 一次只能让一名玩家移动

Question

所以我试图在我的 pygame 游戏中添加两名玩家，但似乎一次只有一名玩家能够移动。当另一个玩家移动被移除时，他们都可以独立移动。如果我删除一个player.move，则未删除的玩家可以移动，但如果我保留两个player.move，那么我放在第一个的玩家是唯一能够移动的。抱歉，如果代码不好，这是我第一次尝试类和所有内容。提前致谢。

我认为最好将事件与类分开，因此如果您创建一个为玩家调用正确成员函数的事件处理程序类/函数将解决此问题。还有事件消耗问题，因为只有这个事件处理程序类必须消耗事件。

喜欢:

def Event_handler():
   if event.type == pygame.KEYDOWN:
       if event.key == ord("w"):
           player_1.up()                    
       elif event.key == ord("s"):
           player_1.down()

其他输入依此类推
