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
) j: R2 m6 ~$ m* k其中有一段如下# } m! c- C6 O
ask turtles with [ infected? = true ]
' q) Y4 f5 l! J" V- Q& ~我原本以为这句会回传『所有』infected? = true 的 turtle6 P- o. m" @# t9 t' }* b
但看结果似乎不是这样。% Z; I4 v0 e6 [' i" G& s% m
/ q9 Z1 e- ]1 ?3 Q1 m
假设所有符合条件的有 5 笔
( a& H1 A' Y* F0 J* b: y p$ L6 [有时候回传 1 笔,有时回传 3 笔,是不固定的
& E' J U/ W; }5 c回头查语法定义4 n. F( O) |7 W: U
with
1 Z% ^: h7 m5 i" t* U/ u9 Magentset with [reporter]" L% ?6 @2 {8 Q- v" t2 i' j
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.
7 b+ R" X% c' n' D7 T& T8 m它只说回传 agents satisfying the given condition
; M1 Q/ j: b4 C/ B! P2 M' A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 ? + \! v6 g" y8 p$ N c: ]
8 {' q/ A$ |3 m8 y* t
想确定一下- q* y, j# G, z: S3 a) q- i5 z/ m
谢谢!
