嗨，我有一点代码“ Wormy.py”，我试图添加一个传送门户。目前，它正在工作，但仅在一个块上运行，由于某种原因，它仅进入第二个whili循环，任何想法为何以及如何解决它？
我尝试添加其他内容：return，但这不起作用，中断也不起作用

希望有人可以提供帮助！
答案 0 :(得分：-1)
我要指出几点： 在外部循环中，您将变量newHead用作数据结构wallCoords的实例，然后在循环内将新值分配给wallCoords。最好将新坐标分配给另一个变量。
在内部循环中，您正在对newHead变量进行完全相同的重新分配。但是内循环中的另一个问题是您再次使用newHead作为wallCoords数据结构的实例。
由于您不断向newHead分配值可能无法解决您最初遇到的问题，因此它肯定会解决所需的代码输出问题。

2nd虽然循环位于第一个循环内，但这是主要问题。尝试重新缩进，然后重新测试您的代码。

if direction1 == RIGHT:
newHead = {'x': startx_wormhole2, 'y': starty_wormhole2}
elif direction1 == LEFT:
newHead = {'x': startx_wormhole2, 'y': starty_wormhole2}
elif direction1 == UP:
newHead = {'x': startx_wormhole2, 'y': starty_wormhole2}
elif direction1 == DOWN:
newHead = {'x': startx_wormhole2, 'y': starty_wormhole2}
