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6 @, {. d1 g, ?4 m8 i" R
其中有一段如下5 e9 U- N' y/ ?+ @
ask turtles with [ infected? = true ] + l7 {! c1 ^6 g# L0 S& i
我原本以为这句会回传『所有』infected? = true 的 turtle& u! A) ?4 I( M8 L0 k0 u
但看结果似乎不是这样。* L4 j& S8 s& N. Y# h
8 M1 I6 L2 P" [ f! ?+ a假设所有符合条件的有 5 笔/ K! O$ ~0 |1 }; O) v
有时候回传 1 笔,有时回传 3 笔,是不固定的
6 u* S7 S- s; D" \! j$ C1 n回头查语法定义
0 X7 [/ m. ], E+ o' w* o0 Xwith
0 i) |1 ]2 Y8 f' u8 Z5 zagentset with [reporter]" P6 S7 x2 H3 S! F8 h
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.
5 t, Y( O L+ a% ?9 T* e2 t2 v它只说回传 agents satisfying the given condition
7 t" c6 [: I8 l/ ~8 F% 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 ? . y6 `) G" f! ?* t
) B( \" T/ {0 I; j9 c+ \1 A
想确定一下8 f q3 R4 A' i: n3 r
谢谢!: b1 h: {; P) M: Q i$ B4 U, o. r0 E
