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5 l. L8 Z- e9 ^* g# m
其中有一段如下
1 L( v2 [' L/ `4 e& Xask turtles with [ infected? = true ] s- i# ~0 X5 K( F1 }
我原本以为这句会回传『所有』infected? = true 的 turtle
* a2 N; ~; z4 `4 ?* E3 k但看结果似乎不是这样。4 z" O! ~8 u# K/ x5 a2 v' L5 Q
9 g" ^) L2 m+ w# e- b假设所有符合条件的有 5 笔/ R0 U, l" @! I; ~ o$ S
有时候回传 1 笔,有时回传 3 笔,是不固定的
% z7 P+ N9 }* D. Q5 i回头查语法定义
6 M2 d; r! \, o* f& y/ ?3 w/ lwith
; k' \! j2 J. O4 I* hagentset with [reporter]) A" c2 [' [3 }5 ^. @4 T) i( V2 G
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.
1 i% m9 x2 `+ F2 @; b7 j g它只说回传 agents satisfying the given condition# q& \4 J C1 q4 |! ? M! R
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 ? , N# K; [& F% I6 u
