netlogo在有限的座標中詢問路徑顏色

Question

我想了解在此有限座標中是否有任何棕色補丁。但這不起作用。我如何查詢它？

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

Answer 1

我覺得你差不多在那裏。像這樣的東西應該工作：

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