如何解决如何解决蛇壁隐形传送的错误
我在做蛇游戏,但遇到一个错误,我不知道该怎么解决,我想让蛇传送槽壁,当蛇与墙碰撞时以相反的速度传送到另一个和位置,就像经典游戏一样,但是使用我的代码,当蛇靠近墙壁时,它会复制到对面的墙壁上,但是应该不会发现碰撞
重要的事情:在网格中,蛇在墙的侧面,像这样
SSSS
WWWW
而不是这样:
SSSS
NNNN
WWWW
当S代表蛇时,W代表墙壁,N则不代表任何东西。

解决方法
您要实现一个传送器。因此,一旦蛇越过在窗户边缘上方,您就必须传送到另一侧。窗口的大小为1020x585。如果 x == -15 , y == -15 , x == 1020 或 y,则蛇不在窗口外== 585 因此,您必须进行以下传送:
- 如果 x = 1020 传送到 x = 0
- 如果 x = -15 传送到 x = 1005
- 如果 y = 585 传送到 y = 0
- 如果 y = -15 传送到 y = 570
_pos = None
if snake[0][0] == -15:
_pos = (1005,snake[0][1])
elif snake[0][1] == -15:
_pos = (snake[0][0],570)
elif snake[0][0] == 1020:
_pos = (0,snake[0][1])
elif snake[0][1] == 585:
_pos = (snake[0][0],0)
if _pos:
snake = [_pos] + snake
del snake[-1]
