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* k+ ?; @( b3 ^) ^8 x* F. m
其中有一段如下% H; M. n. B1 J* e/ g
ask turtles with [ infected? = true ]
7 h. w7 y) A, n( o我原本以为这句会回传『所有』infected? = true 的 turtle
; z U: j2 q& g$ w' g' d" p% l$ k! [但看结果似乎不是这样。( [* S5 v, u# N6 V
4 @/ i/ c5 T0 x; _+ j3 r" z2 ^假设所有符合条件的有 5 笔
: N8 K4 l* B _! D$ c有时候回传 1 笔,有时回传 3 笔,是不固定的
2 i4 b: t; d! }! i/ y回头查语法定义6 }. E- w `9 z' S% v
with 8 F: k, e0 |6 r# n
agentset with [reporter]' I0 d9 ^0 u! 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.. u) d* `+ r8 E7 Q8 x. S9 f
它只说回传 agents satisfying the given condition Q" B- b$ t1 X3 r- D
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 ?
