新手发问超简单问题,目前还处于研读范例码的阶段,边测边看结果来理解程序! F! ?; J* y4 R1 ?3 C: D3 k
其中有一段如下
/ P: L1 G7 m) aask turtles with [ infected? = true ] 2 m' M5 m6 B1 a, d
我原本以为这句会回传『所有』infected? = true 的 turtle
# [% S2 E" c8 b W7 O7 [但看结果似乎不是这样。" N+ i! m) v) g
; j) p+ q: M }假设所有符合条件的有 5 笔
0 h# a% i$ ]9 g0 D7 G; H' R有时候回传 1 笔,有时回传 3 笔,是不固定的, d" ?9 W- y1 {6 Y
回头查语法定义- t% ?0 w( c" q2 ~/ X
with 0 H& E/ Y! `+ e6 h
agentset with [reporter]' i+ z, _, F" [. K" r
Takes two inputs: on the left, an agentset (usually "turtles" or "patches"). On the right, a boolean reporter. Reports a new agentset containing only those agents that reported true -- in other words, the agents satisfying the given condition.3 K3 r/ [! A K* ^
它只说回传 agents satisfying the given condition
% {% E9 u0 X7 ]8 w; q是否 with 回传的是『符合条件』的数据,而不是『所有符合条件』的数据 ? ) ^0 N6 ]6 k2 x
2 R" X/ b, a6 y# M! l' G: w. j; y
想确定一下
( i' M$ a: \2 \$ `( \谢谢!
