NetLogo海龟不断穿过迷宫的墙壁。如何阻止他们穿过墙壁而是让他们改变方向？

我很感激任何帮助。

到目前为止我的代码：

breed [ defaults default ]
defaults-own  [ new-heading ]
breed [squares1 square]
breed [squares2 square]
breed [squares3 square]
globals [ score    ]

to setup-row [row colour segments]
  foreach segments
  [
      if pycor = row * row-patches-width and
        (pxcor >= col-patches-width * (item 0 ?)) and (pxcor <= col-patches-width * (item 1 ?))
          [set pcolor colour]
  ]
end

to setup-col [col colour segments]
  foreach segments
  [
      if pxcor = col * col-patches-width and
        (pycor >= row-patches-width * (item 0 ?)) and (pycor <= row-patches-width * (item 1 ?))
          [set pcolor colour]
  ]
end

to setup-arwels-maze
  clear-all
  set score 0
  setup-defaults 
  setup-squares1 
  setup-squares2
  setup-squares3 
  ask patches
  [     if (pxcor >= min-pxcor and pxcor <= max-pxcor and
        pycor >= min-pycor and pycor <= max-pycor)
          [set pcolor black]

感谢您的时间和帮助。

你必须亲自实施反弹。您的代码不会这样做。无论前方是什么，海龟只会移动1个。

简单的反弹（如球，保留入射角）功能是：

to bounce 
  if [pcolor] of patch-at dx 0 = white [
    set heading (- heading)
  ]
  if [pcolor] of patch-at 0 dy = white [
    set heading (180 - heading)
  ]
end

反弹白斑。请注意，你的乌龟必须朝着它移动的方向“前进”。
