為什么一次只能讓一個玩家移動 Pygame

Question

所以我試圖在我的 pygame 游戲中添加兩個玩家，但似乎一次只能移動一個。 當另一個 player.move 被移除時，它們都可以獨立移動。 如果我刪除一個 player.move，沒有被刪除的那個可以移動，但是如果我保留兩個 player.move，那么我放在第一個的就是唯一一個可以移動的。 對不起，如果代碼不好，這是我第一次嘗試課程。 提前致謝。

我認為將事件與類分開會更好，因此如果您創建一個為播放器調用正確成員函數的事件處理程序類/函數將解決此問題。 以及事件消耗問題，因為只有這個事件處理程序類必須消耗事件。

喜歡 ：

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