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
* b; Z2 u; w# x: s4 n( z其中有一段如下
3 s; Q8 S+ @# B8 j( Lask turtles with [ infected? = true ] # P4 {" x6 A) C+ I( O* j
我原本以为这句会回传『所有』infected? = true 的 turtle( S# S- R, ]6 S5 N) f
但看结果似乎不是这样。
4 o( ~1 n. h/ C- t8 d! l/ f, t: `+ }. V
假设所有符合条件的有 5 笔
2 X9 T a* N" B: { n4 Q/ R8 r有时候回传 1 笔,有时回传 3 笔,是不固定的) D& U0 C# p0 M4 F& b
回头查语法定义' ?5 L1 B) F0 `( t5 O% q6 E7 a
with , Z+ `% U" I( C) c4 I3 M
agentset with [reporter]
6 i1 g! s4 {1 t& [ QTakes 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 p k# Q# w3 H' @- p
它只说回传 agents satisfying the given condition
; D. `, ~- u: v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 ?
6 Q% f# t, `) {8 ]& r* z" s( b, _( S* x( W4 A
想确定一下/ g$ @/ z# R. m; q0 }
谢谢!
