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# }% W0 o! {: ~: Y8 }& }
其中有一段如下
$ o3 A4 f7 c% o# k* ^1 Qask turtles with [ infected? = true ] 5 o( t; g# j. d7 ^
我原本以为这句会回传『所有』infected? = true 的 turtle
Z' J! o4 I: X+ C: J但看结果似乎不是这样。8 y& J. m( W. N1 N. u
8 s q! c! N8 j0 P0 G% ^
假设所有符合条件的有 5 笔- _6 D& ^8 M Z6 \
有时候回传 1 笔,有时回传 3 笔,是不固定的
- n5 `/ h" T; E# z! S5 b回头查语法定义
+ R+ p# g; q1 g0 N. Jwith
r8 y, |5 k4 X) Dagentset with [reporter]5 L2 R+ p: t4 C
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 L2 d4 u" I" i% T; ? o' l5 ^9 U( s它只说回传 agents satisfying the given condition
7 m) [: I7 Q' l/ C" e" 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 ? + A p( ?! \! q
. x3 F! X5 S8 P7 Q& c
想确定一下2 d; D8 k H7 s& c" G3 G2 D
谢谢!: z' k! H6 y7 d* j6 R( q
