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- l- k/ Q1 C/ G$ L3 _
其中有一段如下
% U/ l* G* k- H4 j1 Lask turtles with [ infected? = true ] 7 F6 j6 C7 l/ D( c# }0 N
我原本以为这句会回传『所有』infected? = true 的 turtle, I V5 T8 }# s5 q1 ^) @) Q" e# t. U
但看结果似乎不是这样。: P# p$ U( ^; y0 O9 ~* {
0 n3 S2 {# C7 H. D' _5 `( A
假设所有符合条件的有 5 笔) u, j! P1 r8 o8 n
有时候回传 1 笔,有时回传 3 笔,是不固定的: a& w6 o7 m; l# m
回头查语法定义, \, S5 u Z# j
with
& h! D h8 L" L- ^agentset with [reporter]
# x. r, i4 ~ Z( S7 ~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.
, w& W$ j/ \ a! _它只说回传 agents satisfying the given condition* H6 @ B, ~# h: k$ e& c2 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 ?
; o; z+ E- \( A0 @3 A$ B7 H' J0 |' P8 ^* S" {( R
想确定一下
, ?5 F9 ?4 M3 E' R1 C$ ~# b谢谢!! G3 U# [ a! N; w* M
