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( \& E: l3 `/ r8 m, J
其中有一段如下
3 t, P; A7 u& \' I+ W4 `* kask turtles with [ infected? = true ] , `2 y2 r8 t B
我原本以为这句会回传『所有』infected? = true 的 turtle
+ i0 E9 `5 _* \) J% W- p但看结果似乎不是这样。, J) E8 z& |$ U5 t+ {1 x
- A4 r7 D" ]2 O5 ]假设所有符合条件的有 5 笔
9 V6 s7 ?5 |1 \4 i7 ^0 ?) M( Z有时候回传 1 笔,有时回传 3 笔,是不固定的
. s6 t; U& s. h0 y0 F3 d) K回头查语法定义 A( a6 D$ S5 ^2 S& a4 {
with
7 o9 e9 S9 ^! o! tagentset with [reporter]
1 N( G% Q) h! Q. }! @6 \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$ W+ t( S7 B8 f6 B) @8 l' {
它只说回传 agents satisfying the given condition# v! F7 ?7 I/ ~$ i! p5 [
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 ?
; l; `: c+ K2 j# e ], P# x, P( R [* h. m) S5 ~
想确定一下1 f* u5 V- X2 H) S
谢谢!
