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" H$ G6 I3 [3 J/ s
其中有一段如下
! d$ R3 `. W1 mask turtles with [ infected? = true ] 1 b: D9 g$ L4 _8 d0 c( m3 a- h6 P
我原本以为这句会回传『所有』infected? = true 的 turtle
( {9 O6 x, m0 w9 K' A6 N2 x但看结果似乎不是这样。- D* ] O9 p& m0 d" S7 z6 e8 P
1 h* W, q+ N0 e; C5 d
假设所有符合条件的有 5 笔5 P1 ? g' Q2 J7 n7 U6 l
有时候回传 1 笔,有时回传 3 笔,是不固定的
* I. @! _: \" R* h* j$ J回头查语法定义7 v7 {8 E" P0 ^+ ?2 e
with
* M( x* O3 ?9 j2 @# N' x6 zagentset with [reporter]
0 K7 {; J- Z6 k4 ~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.
W4 n1 w8 f% H它只说回传 agents satisfying the given condition' T5 \1 f. t9 |0 c% a6 F. H5 ?2 z
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 ?
