python - Pygame 键盘动画无法正常工作

所以问题是，每当我按下右键时，动画就会从左侧屏幕上滑落。当您将手指从琴键上移开时，动画不会停止。我自己搜索过问题，但找不到任何问题。如果您发现可能导致问题的原因，请告诉我。谢谢! (上键=下，下键=下，右键=左，左键=左)

您的问题是您将 move_x 和 move_y 交换为 K_RIGHT 和 K_UP。

            elif event.key == pygame.K_RIGHT:
                move_y = 3

            elif event.key == pygame.K_UP:
                move_x = -3

应该是:

            elif event.key == pygame.K_RIGHT:
                move_x = 3

            elif event.key == pygame.K_UP:
                move_y = -3
