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8 v" X& L' P2 t7 o" D4 m
其中有一段如下
- z" S! V) x; h3 B( g1 X6 Cask turtles with [ infected? = true ] ' Y4 Z" v+ B- K* F- \
我原本以为这句会回传『所有』infected? = true 的 turtle+ d* Z4 C' B7 @) Y6 k7 h( J! B* x& ]
但看结果似乎不是这样。
( o( `* {! T6 o( n( Z1 q) }/ g% x, B+ P
假设所有符合条件的有 5 笔
8 V7 G' F$ |9 s5 ] M/ c有时候回传 1 笔,有时回传 3 笔,是不固定的
+ q; b7 V2 J; R$ c回头查语法定义* }8 z% g* @8 p" Z
with
N: m8 q8 C4 I9 A# {agentset with [reporter]# x4 k% M( j# ]. h
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.+ I8 T, C+ ?. D& c- y0 Q8 ?
它只说回传 agents satisfying the given condition4 Z& x+ u- X) v7 p
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 ?
' p/ H# x# { `3 D1 P
7 E. a. M$ N [) p e想确定一下
; ], W L7 I6 e1 l$ o( `谢谢!: d' s+ U" p4 a
