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/ y* ?0 c$ D/ a4 ~$ ~
其中有一段如下5 Q3 `6 q- M5 O3 [& \
ask turtles with [ infected? = true ]
4 | T0 B: f& S( ~5 ?2 X我原本以为这句会回传『所有』infected? = true 的 turtle1 j, b0 y U- x4 v5 u* s5 L
但看结果似乎不是这样。' ?* l& V, }6 ?, \8 r0 k+ V
! ?( |% }, K' B5 ^假设所有符合条件的有 5 笔* `( z' c' q+ ?+ U$ a1 r; U# \! x
有时候回传 1 笔,有时回传 3 笔,是不固定的
* E, g* P+ r/ y/ _回头查语法定义
6 k3 A0 C- B! V: Owith
1 |( H! i2 [- J g( Uagentset with [reporter]' } a. `( f+ e# C8 u+ A( Z! R
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.* K( L! H3 H' b9 C
它只说回传 agents satisfying the given condition; s0 g# l9 O+ C& y7 j4 u7 U$ M9 F
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 ?
& H# Z; X! Y7 d4 |. j$ ~+ \0 P+ J/ w. R# e$ V2 o
想确定一下8 _ ^! u+ M. E8 g1 o4 N
谢谢!( D* ]9 w6 N& K! X
