NetLogo：select 具有特定品质的邻居的补丁？

Question

我想让我的乌龟移动到某个补丁并制作一个"splotch"。 central patch = my turtle location，可以随机选择，但要满足两个条件：

必须与乌龟的实际位置有一定距离
必须被具有特定质量的补丁包围（特定半径内的邻居）

原因是在我的乌龟位置周围创造了一种"buffers"，目的是阻止我的团块靠近。

请问如何满足这两个条件？

到目前为止，我有：

to go
 ask turtles [                 
   ; select one of patches in specific distance, and 
   ; surrounded by patches with no magenta color
   let aaa one-of patches with [distance myself > 3 and   
       all? neighbors with [pcolor != magenta]] 
                      ; how to write this condition above ?? 
                      ; and how replace "neighbors" by "in-radius"??
   move-to aaa
   ask neighbors [           ; create clump of magenta patches
     set pcolor magenta ]
   ask patch-here [          ; set central patch to magenta
     set pcolor magenta ]
 ]

Answer 1

你快到了；您只需要重新阅读 all? 和 any?.

的文档

let _candidates patches with [distance myself > 3]
set _candidates _candidates with [
  not any? (patches in-radius 3 with [pcolor = magenta])
]
let aaa one-of _candidates

如果有可能没有应聘者，就要提防了。
