我有这个代码设置年龄段孩子,成人和老年人。如何使用滑块设置一些女性? 我只想建立女性和男性。就像你将滑块设置为30%一样。从孩子,成人和老年人中30%将成为女性

答案 0 :(得分:2)
假设所有海龟都有is-female?
属性和名为percent-female
的滑块:
turtles-own [is-female?]`
一种方法是计算每个人口的30%,例如:
ask n-of (percent-female / 100 * count kids) of kids [set is-female? true]
另一种,更多的是 Nelogo-ish 方式,在创造孩子,成人和老人时,将以概率的方式进行。例如:
ask kids[
if random 100 < percent-female [set is-female? true]
set color green
if(body > 0.9)[
set size body]
setxy random 19 random 80
facexy 18 43]
