生成大小和位置随机的河流

问题描述

我正在做一个较小的项目，有一个问题找不到解决方案.

I'm working on a smaller project and have one issue I can't find figure out any solutions for.

我要 随机生成河流 .我的计划是随机产生多条大小和位置各异的河流.有人知道如何随机产生河流吗?

I want to randomly generate rivers. My plan is to randomly generate a number of rivers with varying sizes and locations. Does anyone know how to generate rivers randomly?

我尝试了几件事.我确实设法生成了此，但我希望它更像河流(直行)，并减少聚集".

I have tried several things. I did manage to generate this, but I want it to be more like rivers (straight lines) and less 'clustered'.

我使用以下代码获取了上图.

I used the following code to get the picture above.

; Generating random rivers.
ca
ask patches with [pycor = (random 16) or pxcor = (random 16)]
[
  set pcolor brown
  ask patches in-radius random 3 [set pcolor brown]
]

感谢您抽出宝贵的时间！

Thanks for taking your time!

我取得了一些进展，看起来像此.这是我设法达到的最接近的目标.

I made some progress, it looks like this. This is the closest I've managed to get to what I want.

to setup
 ca
ask n-of 2 patches [
      spread-right
    ]
    ask n-of 2 patches[
      spread-left
    ]
    ask n-of 2 patches[
      spread-down
    ]
    ask n-of 2 patches[
      spread-up
    ]
end

to spread-right
   if pxcor < max-pxcor [
    ask n-of 1 neighbors with [ pxcor = [pxcor] of myself + 1] [
      set pcolor brown
      spread-right
    ]
  ]
end
to spread-left
  if pxcor > min-pxcor [
    ask n-of 1 neighbors with [ pxcor = [pxcor] of myself - 1] [
      set pcolor brown
      spread-left
    ]
  ]
end

to spread-down
  if pycor > min-pycor [
    ask n-of 1 neighbors with [pycor = [pycor] of myself - 1][
      set pcolor brown
      spread-down
    ]
  ]
end

to spread-up
  if pycor > max-pycor [
    ask n-of 1 neighbors with [pycor = [pycor] of myself + 1][
      set pcolor brown
      spread-up
    ]
  ]
end

推荐答案

您可以简单地使用(半)随机行走的乌龟四处走动并为其行走的斑块着色.然后使用您的扩展代码在某些地方使其更粗.

you could simply use a (semi-)random-walk turtle to walk around and color the patches it walks on. Then use your spread-out code to make it thicker in some places.
