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5 z0 O& U% z# X% b& M* j
其中有一段如下
: O! i5 u$ v! G$ gask turtles with [ infected? = true ] 3 [, [ y7 v D
我原本以为这句会回传『所有』infected? = true 的 turtle
8 b- Y d. o% J2 S ?2 a. w Z但看结果似乎不是这样。7 d0 ?/ |0 B9 C; K5 p* t
. L M/ M, H6 q假设所有符合条件的有 5 笔$ _; t5 Y# ?" c. i& U' _' \" J
有时候回传 1 笔,有时回传 3 笔,是不固定的/ t" \8 w$ E& T$ C6 @* h2 i
回头查语法定义
" T! s" v( c) S. ]8 Ewith
2 y) q1 E* E& v# m3 B4 C' K. |agentset with [reporter]
2 A/ N4 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.% ?; U3 I U8 G6 ~( M; u+ V
它只说回传 agents satisfying the given condition9 Z- g8 s+ w- i% n5 p7 L1 Y( D
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 ?

想确定一下
