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
; ?& d$ B# D% V" o$ a0 z' k# t0 q其中有一段如下. {2 [2 P& u6 i# p v l
ask turtles with [ infected? = true ] 4 w: Y* q: T. j- ]7 c
我原本以为这句会回传『所有』infected? = true 的 turtle
+ v& I O( G0 b* K但看结果似乎不是这样。% R3 v- U9 F, u( D+ j! j
8 L6 I: l& p: s+ n/ y$ C6 j
假设所有符合条件的有 5 笔6 }; z& T$ o; e. r) d x5 { W& y$ E
有时候回传 1 笔,有时回传 3 笔,是不固定的/ u N# R# v1 d2 n
回头查语法定义; l* D: R2 K# d% ?% J# O$ v
with 3 h3 }( `+ U9 Q: }! P& l" A" b
agentset with [reporter]3 ^) z# y6 Q: I2 O# k) @
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.: U0 T1 P2 i1 H. N$ `. f
它只说回传 agents satisfying the given condition
0 m- z( k5 g+ z$ ~1 n5 t8 l5 l( g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 I, y3 H4 x2 l g# i- G2 L
/ O" u1 i! e& ]3 p3 B
想确定一下" g# P* k2 v V" w3 ]8 _9 [1 i
谢谢!( I, M% ^; a+ e% _4 S
