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+ K7 n1 w8 B$ m
其中有一段如下3 A+ ~ H w2 \9 \8 c$ ?# V
ask turtles with [ infected? = true ]
9 b0 \* s' k! D7 F我原本以为这句会回传『所有』infected? = true 的 turtle/ T# R3 `: {5 k* } A
但看结果似乎不是这样。* o, w; p% Y5 \3 a/ P
! R- d( ]/ x7 S. q( J% h
假设所有符合条件的有 5 笔
' u' X4 Y+ r% f ~有时候回传 1 笔,有时回传 3 笔,是不固定的
2 F* g5 o- h: D回头查语法定义
' Z' H2 C: t: M2 s7 B* Fwith

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.( u+ S/ j7 s- F' L; N
它只说回传 agents satisfying the given condition) m9 {" P9 V& B0 U
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 ? / n7 I) w# J9 s

想确定一下
