这是一个简单的俄罗斯方块小游戏的Python代码示例。在实现游戏逻辑和显示方面已经有了基本的框架,但是还需要完成键盘事件的处理部分,以及根据游戏规则更新方块位置、判断碰撞、消除行等功能。由于篇幅限制,无法完整呈现所有代码,请根据以下代码进行补充:
```python
# ...
                    elif event.key == pygame.K_DOWN:
                        ve_down()
                    # 其他方向键操作类似
            self.update()
            screen.fill(BLACK)
            self.draw_grid()
            self.draw_score()
            pygame.display.flip()
        pygame.quit()
    def move_left(self):
        for block in self.current_block:
            <= 0 or \
                    // BLOCK_SIZE][( - BLOCK_SIZE) // BLOCK_SIZE] is not None:
