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
3 F1 _8 q3 Z: f- ?/ H+ G7 I1 e其中有一段如下) U/ \+ f3 y: x( ~% s$ `) r
ask turtles with [ infected? = true ] 3 O8 s$ l* E0 d+ u
我原本以为这句会回传『所有』infected? = true 的 turtle5 Y$ ^/ {8 t% c, Q5 i2 L
但看结果似乎不是这样。8 J7 o6 _: c9 [' W3 a
; P9 V7 Y5 ]- a+ Q7 C9 A) g
假设所有符合条件的有 5 笔- u0 o, o$ Q. N) S
有时候回传 1 笔,有时回传 3 笔,是不固定的0 u9 V$ {2 I( G/ M
回头查语法定义
& l' u3 d" U, M+ k# b( bwith
0 |% B+ S+ _9 ?2 }( Hagentset with [reporter]3 N9 k' w7 h2 u
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.$ A Q) r% A1 M
它只说回传 agents satisfying the given condition6 G9 [1 u$ Y1 O/ r
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 ? + x# o+ V0 C: ]5 s

想确定一下
