我正在做一个游戏，但是当它玩几次时，当它穿过障碍物时，向右按就可以穿过墙壁。我的代码有什么问题？我正在使用python 2.7。
我尝试放入许多代码，例如x> displaywidth + 10。我尝试制作不同的副本。但是蛇仍然穿过。

我希望屏幕上显示游戏的输出，但实际输出是通过的蛇。
答案 0 :(得分：0)
当lead_x >= dw或lead_y >= dh而不是lead_x > dw lead_y > dh时，蛇超出范围。
绑定检查必须为：
if lead_x >= dw or lead_x < 0 or lead_y >= dh or lead_y < 0:
gameOver = True
但是我建议改用pygame.Rect.contains。 .contains()验证一个矩形是否完全在另一个矩形内：
if not pygame.Rect(0, 0, dw, dh).contains(lead_x, lead_y, bs, bs):
gameOver = True
