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" L5 a' M: b" a/ M+ s) M6 f
其中有一段如下
- g# d9 ^9 o. g6 Q, W+ jask turtles with [ infected? = true ] * R2 Y* H! \8 L) _4 k+ \
我原本以为这句会回传『所有』infected? = true 的 turtle1 r. a$ Q1 S* e: t) v7 _
但看结果似乎不是这样。. e# q( o4 p5 u: B
6 A" ]. b( \% W- v假设所有符合条件的有 5 笔1 N# ?$ P- n1 K% P+ x) k9 o* R
有时候回传 1 笔,有时回传 3 笔,是不固定的$ K% ^6 l$ M) J, R# ]! r8 o, v5 n
回头查语法定义
7 R5 P$ S2 E t4 O5 fwith ) x; _- C5 Z/ k% i" V5 {; G
agentset with [reporter]( F' i8 }7 |( t9 T! q/ B
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.# N3 ~9 t& ]$ R U
它只说回传 agents satisfying the given condition
# @) s4 y7 @/ d' k9 c" 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 ? % X- d+ F4 H* q/ j3 s: m4 ?
$ l) ]2 W8 i7 j \' t" T, v想确定一下
% }: K' z5 h; `2 S3 {& N谢谢!$ {, h6 ? E; s1 N
