Netlogo定期发芽的海龟

问题描述

我想以指定的步长将海龟放在每个黑色补丁上(如下图所示):

I want to place turtles on each of the black patches(below Figure) at a specified step size:

因此，如果步长较小，那么将创建/发芽的海龟更少，而步长较大的情况下，将导致更少的海龟.

Therefore if step size less more turtles will be created/sprouted and more step size will result in less turtles.

我现在使用的代码:

ask patches with [pcolor = black][sprout-dead-turtles wall-agents [set color red]]

这将产生以下结果:

This gives the following result:

推荐答案

此处:

to fill-wall [ d ]
  set d precision d 1 ; make sure d is a multiple of 0.1
  let n precision (d / 0.1) 0 ; interval at which to hatch
  ask one-of possible-next-patches [
    sprout 1 [
      hatch 1
      let i 0
      let next-patch my-next-patch
      while [ next-patch != nobody ] [
        face next-patch
        while [ patch-ahead 0.55 != nobody and [ pcolor ] of patch-ahead 0.55 = black ] [
          fd 0.1
          setxy precision xcor 1 precision ycor 1 ; avoid floating point imprecisions
          set i i + 1
          if i mod n = 0 [ hatch 1 ]
        ]
        set next-patch my-next-patch
      ]
      die
    ]
  ]
end

to-report possible-next-patches
  let empty-black-patches patches with [ pcolor = black and not any? turtles-here ]
  report empty-black-patches with [
    count neighbors4 with [ member? self empty-black-patches ] = 1
  ]
end

to-report my-next-patch
  report one-of possible-next-patches with [ member? self [ neighbors4 ] of myself ]
end

这是您将如何使用它:

to setup
  ca
  ; draw the background:
  ask patches with [ abs pxcor != max-pxcor and abs pycor != max-pycor ] [ set pcolor grey ]
  ask patches with [ pycor = max-pycor and abs pxcor <= 1 ] [ set pcolor white ]
  set-default-shape turtles "circle 2"
  fill-wall 0.3
end

约束:

• d必须是0.1的倍数
• 世界包装需要关闭

• d has to be a multiple of 0.1
• world wrapping needs to be turned off
