问题描述
我在做蛇游戏，但遇到一个错误，我不知道该怎么解决，我想使蛇能传送到槽壁上，当蛇与墙壁相撞时，它会以相反的速度传送到另一条壁上位置和位置，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，但是它甚至还没有发现碰撞
I'm doing a snake game and I got a bug I can't figure out how to solve, I want to make my snake teleport trough walls, when the snake colllides with a wall it teleports to another with the opposite speed and position, like the classic game, but with my code when the snake gets near the wall it duplicates to the opposite wall, but it was supposed to not even detect collision yet
重要的事情:在网格中，蛇在墙的侧面，像这样
important thing: in the grid the snake is on the side of the wall, like this
SSSS
WWWW
而不是这样:
SSSS
NNNN
WWWW
当S代表蛇时，W代表墙壁，而N则不代表任何东西.
when S represents the snake, W represents the wall and N represents nothing.

推荐答案
您要实现一个传送器.因此，一旦蛇越过在窗口边缘上方，您就必须将其传送到另一侧.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:
You want to implement a teleporter. Therefore, once the snake is over the edge of the window, you will have to teleport to the other side. The size of your window is 1020x585. The snake is out of the window if x == -15, y == -15, x == 1020 or y == 585 Hence you have to do the following teleportations:
- 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
- if x = 1020 teleport to x = 0
- if x = -15 teleport to x = 1005
- if y = 585 teleport to y = 0
- if y = -15 teleport to 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]
