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
- ~: y/ F) U6 J5 e) K其中有一段如下4 M8 m0 i6 A8 W
ask turtles with [ infected? = true ]
4 V- }3 Z7 n5 [4 a/ w9 |6 X- O; R我原本以为这句会回传『所有』infected? = true 的 turtle
- [% n7 }8 R1 Q$ M% X0 b, p但看结果似乎不是这样。& d1 e$ ]# K# C2 n$ F, `
2 e& b' [0 ~6 O% ?
假设所有符合条件的有 5 笔
6 J( s2 J2 t% p7 ^$ H/ K有时候回传 1 笔,有时回传 3 笔,是不固定的
6 [2 l: }) T* H( X3 e+ K& [/ a回头查语法定义
7 d) x; k- x% P; twith
6 |! m$ b" u! z" u6 c9 }1 x$ Cagentset with [reporter]% k5 o; l7 \7 M) d& a
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.0 z) J: g% S, D" L7 P& c
它只说回传 agents satisfying the given condition3 `; ]6 }; M* u2 q/ x' t
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 ? : q5 G5 C, P$ @* H5 s- T
. Q+ j0 z* ` e7 w* c, _& L想确定一下9 R* W3 Z* m Q" ]0 M
谢谢!/ q. X; L% Z& X- f9 J+ p
