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
& ?2 `2 d H+ R; o! y- s% \其中有一段如下
" P1 M. h8 X0 Z/ t# D, @' W. N: wask turtles with [ infected? = true ] & M2 N3 C& K3 n/ X# E
我原本以为这句会回传『所有』infected? = true 的 turtle
! _5 k; v' L; A5 m, B. W但看结果似乎不是这样。
. ^! L h& q# f+ S2 k5 e
3 v' [* Q/ w7 q假设所有符合条件的有 5 笔
. Y3 m0 N. U- M, W有时候回传 1 笔,有时回传 3 笔,是不固定的
- |" B* E& \; x% J: B3 t( ~回头查语法定义0 \2 g+ E" i; ^$ \' p

agentset with [reporter]
* M7 n0 m5 _) C5 a w) J4 n- g) lTakes 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.) b! }& [7 W' ?5 T! k1 b) \6 v0 l
它只说回传 agents satisfying the given condition ?/ `" W1 P% W# a u/ }; O
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 ? ( W3 h6 m3 M5 o' N6 E* I2 E: ~- s

想确定一下
. n4 r2 i% S3 f! \/ e" R谢谢!
