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- P3 a1 r L. g+ V
其中有一段如下
! p! X6 I# S9 u& G4 {/ q$ R4 \; x9 qask turtles with [ infected? = true ]
- n$ w: [. m1 G" Q我原本以为这句会回传『所有』infected? = true 的 turtle
- F: s! p% u/ ]7 F# b% E% s' |) \但看结果似乎不是这样。1 f* M4 u! z5 q/ h4 T4 D
5 F! t# W! \' @8 F8 r+ m6 n3 @. k假设所有符合条件的有 5 笔
) @: a% m! w" s# v% X有时候回传 1 笔,有时回传 3 笔,是不固定的+ }/ P+ o: Q D' j) p, B- A7 t1 G
回头查语法定义! G, V, L& H" B j" P

agentset with [reporter]
7 Z) I' k- s1 D2 U. x+ ?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 Y" _2 T! _1 u' L; L4 a. C7 g它只说回传 agents satisfying the given condition
4 U1 X5 k3 E! G% ]5 ]$ n" S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 ? 9 u# x9 o# d7 ?7 T' W5 U9 s4 O
