如何在补丁集群周围绘制边缘？

Question

我想在森林周围划出30米的边缘（见下图）。这是我的代码（1补丁= 10米）

to create-forest-edges
let forest-edge 30
set patch-side 10

ask patches with [pcolor != 53] [
ask neighbors with [pcolor = 53] [
set pcolor green ] ] 

repeat (forest-edge / patch-side) - 1 [ 
ask patches with [pcolor = green] [
ask neighbors with [pcolor = 53] [
set pcolor green ] ] ] 
end

位于世界极端的一些补丁没有绿色边缘。我不知道为什么？ 非常感谢您的帮助。

Answer 1

相反如何：

ask patches with [pcolor = 53] [
  ask patches in-radius 3 with [pcolor != 53] [
    set pcolor green
  ]
]

Answer 2

森林必须距离边缘至少3个补丁才能工作。因此，在您的林生成代码中，只需确保边缘附近没有任何补丁被着色为森林。
