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3 k0 }6 ~$ z, U1 W6 B+ E; k, y
其中有一段如下0 \! t; ~8 T5 N7 D" O
ask turtles with [ infected? = true ] * \: y- z1 I, K) l
我原本以为这句会回传『所有』infected? = true 的 turtle1 D3 A- U! m8 m# ~
但看结果似乎不是这样。0 X# T' \) J% Q2 A! ?8 o9 }! i- |( I9 d
& F' } q' M% M! {; I& }! D
假设所有符合条件的有 5 笔& p/ S8 ^9 K2 y. Q* z& m
有时候回传 1 笔,有时回传 3 笔,是不固定的
& L1 i0 p$ N4 D$ N' @& e回头查语法定义
/ n6 D0 O* y9 ?1 Awith 7 q4 V/ k: @+ J" U2 F x
agentset with [reporter]
0 ^' M! n8 @# c7 Y# eTakes 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.; @4 d( O+ j: Q( s. h
它只说回传 agents satisfying the given condition
+ }7 d' y; P! ?& I Y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 ?
- B, E/ R3 [9 ^' s; @$ D, G0 V: r/ b9 a$ k6 k& T
想确定一下
& O, N6 u9 t- `+ t; A谢谢!
