netlogo - netlogo 在有限坐标中询问路径颜色

Question

我想知道在这个有限的坐标中是否有棕色的补丁。但这不起作用。我该如何查询呢？

if not any? pcolor = brown with [ (pxcor >= max-pxcor - boundary-width) or (pxcor <= min-pxcor + boundary-width)][fd 2]

Answer 1

我想你就快到了。像这样的东西应该工作：

  if not any? patches with 
    [ pcolor = brown and 
      ( pxcor >= max-pxcor - boundary-width) 
        or (pxcor <= min-pxcor + boundary-width) ]
    [ fd 2 ]
