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! D7 F6 p2 T1 [, M" {7 i+ D0 w
其中有一段如下* v& u5 H' X9 C3 W) z9 R+ |
ask turtles with [ infected? = true ] 0 V: p* X# ~% H+ u, k9 s; _
我原本以为这句会回传『所有』infected? = true 的 turtle$ _) F W( H$ w+ u5 s
但看结果似乎不是这样。) W% |$ E& n6 T3 D& I% V; J
7 g) N9 h! }8 C) j2 W
假设所有符合条件的有 5 笔6 H7 |# ~" E" X( T3 |) B8 e s
有时候回传 1 笔,有时回传 3 笔,是不固定的
4 Y; n& L6 n' p- D! [/ e回头查语法定义
9 U: s5 c1 P3 }# u) G( Wwith
& O% |* o2 C/ q+ Z+ x0 E$ Z7 c# m1 R5 Kagentset with [reporter]/ y# N8 X( P. f; p
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.
# n/ B7 \: N+ @0 n+ @它只说回传 agents satisfying the given condition, f3 {$ K7 n+ ?7 y W4 ^' G( {
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$ O4 D0 P/ A' w5 V# b/ [: m* e! b
想确定一下+ {: N5 U# X3 ]# @ p
谢谢!
