netlogo - 海龟从一种繁殖到另一种

我对netlogo不太了解，所以这可能是一个非常简单的解决方案，但是我有多种海龟，每个海龟的年龄都不同(蛋，孵化器，幼鱼，(成人))，我需要它们能够走在经过一定数量的滴答之后从一个品种到下一个品种(在我的模型中，一个滴答=一天)。这可以编码吗？

到目前为止，这是我的代码

globals [island]

Breed [eggs egg]
Breed [hatchlings hatchling]
Breed [juveniles juvenile]
Breed [hawksbills hawksbill]

turtles-own [
  age
  z
  ]

to setup
  clear-all
  set-default-shape eggs "circle"
  create-eggs 80
  [ set color 49.5
    set size 0.5
    setxy random-xcor random-ycor ]

  set-default-shape hatchlings "turtle"
  create-hatchlings 70
  [ set color 57
    set size 1.5
    setxy random-xcor random-ycor ]

  set-default-shape juveniles "turtle"
  create-juveniles 10
  [ set color 55
set size 2
setxy random-xcor random-ycor ]

set-default-shape hawksbills "turtle"
  create-hawksbills 9
  [ set color 53
    set size 3
    setxy random-xcor random-ycor ]

  clear-output
  setup-environment
  setup-birthdays
  reset-ticks

end

to setup-environment
  ask patches [set pcolor cyan]
  ask patches with [abs(pxcor) < 5 and abs(pycor) < 5] [set pcolor yellow]
  ask patches with [abs(pxcor) < 2 and abs(pycor) < 2] [set pcolor brown]
end

to setup-birthdays

end

to go
  ask eggs
  [ kill-eggs ]
  ask hatchlings
  [ move-hatchlings
    kill-hatchlings]
  ask juveniles
  [ move-juveniles
    kill-juveniles]
   ask hawksbills
  [ move-hawksbills
    kill-hawksbills
    reproduce-hawksbills ]

  tick
  if not any? turtles [stop]
end

to kill-eggs
   set z random 100
   if z > 50
    [die]
end

to kill-hatchlings
   set z random 100
   if z > 10
   [die]
end

to kill-juveniles
   set z random 20
   if z > 18
   [die]
end

to kill-hawksbills
   set z random 5
   if z > 4
   [die]
end

to move-hatchlings
  rt random 360
  fd 1
end

to move-juveniles
  rt random 360
  fd 1
end

to move-hawksbills
  rt random 360
  fd 1
end

to reproduce-hawksbills
     if pcolor = yellow
     [set z random 100
     if z > 75
     [hatch-eggs 5[
         set color 49.5
         set size 0.5]
     ]]
end

最佳答案

要将乌龟变成小鱼，只需执行set breed hatchlings即可!因此，您的代码可能类似于:

if age > 10 [
  set breed hatchlings
]
