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+ G! b i8 A; O) n' E
其中有一段如下% T$ ^- P1 O' {, D9 d
ask turtles with [ infected? = true ]
3 _. f% y8 i* ]4 a* D我原本以为这句会回传『所有』infected? = true 的 turtle
/ H3 N8 @. M3 x! \1 D但看结果似乎不是这样。
2 o5 W& C. \: A; D
, \% |5 F6 P. E7 d+ z假设所有符合条件的有 5 笔
3 U- c t- J- {) b# S有时候回传 1 笔,有时回传 3 笔,是不固定的' [$ I: k/ W( k$ `9 p. n2 @
回头查语法定义2 ?8 u8 q* U. y
with
9 U1 m" E2 ^4 `& d/ U3 c' lagentset with [reporter]
' _1 Z9 c( `+ ?2 Z2 k5 qTakes 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.* F! I1 ^9 p$ a) E& G; `: {( Q5 Y. I
它只说回传 agents satisfying the given condition
/ \) O/ v+ [0 ?1 x0 F% Y3 e 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 ? 8 b/ P( j; [& m
: B* K! V& f4 Z- i+ L想确定一下
