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" O+ I# \9 ~( m$ _0 ~# {% o- X* r2 W
其中有一段如下
9 L1 _- Z- |- O* P9 q0 kask turtles with [ infected? = true ]
0 _3 O" [6 \% p' F% |7 J0 g% u& i我原本以为这句会回传『所有』infected? = true 的 turtle
; H. M& \# v3 F2 [" |4 p7 e但看结果似乎不是这样。
; \$ ?% a5 @, c4 c7 C# \
. t5 n9 f' x7 W6 R' ~: B$ X2 ~假设所有符合条件的有 5 笔& K% ]" M9 q" ~# N
有时候回传 1 笔,有时回传 3 笔,是不固定的
; W" s& O% e6 u+ m# [/ {回头查语法定义
5 g* o6 P5 P& Y% t! b' awith 2 t7 _9 {7 r. G4 @+ D
agentset with [reporter]
. t9 U0 u0 [) q2 F+ w+ e4 ^5 ?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.
1 ~( Y3 b& v; k! X! }1 l. \它只说回传 agents satisfying the given condition3 x3 Y' _* y4 g5 j1 |9 v( q$ M
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 ? " E2 {, I7 O* z( N! E. \
" v2 A: g! S% n) C7 X
想确定一下
7 n; G+ h. f. w [' [谢谢!7 c% V4 J, H' x. u0 Z/ M3 o
