NetLogo使品种在某些补丁中产卵

Question

我是NetLogo的新手，我希望这是一个简单的问题。我创建了两个品种[ redteam redsoldier]＆amp; [blueteam bluesoldier]我要做的是让不同的品种在特定的补丁中产生。所以红队只能在窗口的一半（红色区域）中随机产生，而蓝队则在另一个（蓝色区域）中随机产生，但是在尝试多个if和while语句和其他东西后，海龟只产生于屏幕中心。

有什么想法吗？

globals [
red-patches
blue-patches 
]

;; note patches could not be set to only green as this partly clashed with soldiers     uniform

breed [ redteam redsoldier]
breed [ blueteam bluesoldier]

to setup
clear-all
setup-turtles
setup-patches
reset-ticks
end

to setup-turtles
create-redteam 10
 [
   set shape "person soldier" ;;need to import person soldier shape!
   setxy random-pxcor random-pycor
   set size 1.5
 ]

create-blueteam 10
 [
   set shape "person soldier" 
   setxy random-pxcor random-pycor
   set size 1.5
 ]
 end

to setup-patches
;; create red territory
set red-patches patches with [pycor < 0]
ask red-patches [ set pcolor green - 3 ]

;; create blue territory
set blue-patches patches with [pycor > 0]
ask blue-patches [ set pcolor green - 2 ]  
end

Answer 1

一种简单的方法是使用sprout。

以下是setup-turtles的新版本（需要在 setup-patches之后调用）：

to setup-turtles
  ask n-of 10 red-patches [
    sprout-redteam 1 [
      set shape "person soldier"
      set size 1.5
    ]
  ]
  ask n-of 10 blue-patches [
    sprout-blueteam 1 [
      set shape "person soldier"
      set size 1.5
    ]
  ]
end
