Networking 海龟在网络中选择路径

我在建模方面是个新手，我正在使用NetLogo，我已经创建了与海龟品种的链接，我称之为bstations。我想做的是让海龟（人）移动到一个中间站，但这是一个连接到他们想去的地方的链接

 ask persons with [ starting_station = ["Station 4"]] ;;these 

[ let currentstation bstations-here
   let availabledestinations nobody
   ask currentstation [ set availabledestinations link-neighbors ]
        let destination nobody
    ask availabledestinations [ if link-neighbors = bstations with [link-neighbors = bstations with [label = "Station 4"]] [ set destination self ]] *;; this is the code line that i am trying but it does not seem to work*
    if destination != nobody [ move-to destination] ]

我不完全清楚您想做什么，但我想您应该检查一下网络（nw）扩展。有一些有用的原语可以帮助您识别路径上的所有海龟
