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: l" O$ s- b8 j% J7 U
其中有一段如下
2 J/ D; w) d4 u [% |) o/ Oask turtles with [ infected? = true ] 7 o9 g) ~6 U' A3 E, j2 [; F
我原本以为这句会回传『所有』infected? = true 的 turtle3 r: b# {1 C5 u& b; ^% |
但看结果似乎不是这样。
9 J1 W, Z2 L% _# U4 ]3 `! M! E9 \
假设所有符合条件的有 5 笔
, [2 W4 R" Q9 S' D有时候回传 1 笔,有时回传 3 笔,是不固定的' ?: }% s$ d1 j
回头查语法定义+ K" W! [; D0 Q% I( O5 g7 e
with
4 h! A* a6 ?: i5 z1 U1 Tagentset with [reporter]
; Y8 \ s6 w C2 @/ mTakes 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 W, B! W0 B1 p/ B; e它只说回传 agents satisfying the given condition
7 w Z1 o+ j' f- @: I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 ?
, @4 v% D6 K5 e8 e# s' T+ }) ~/ s, x7 w$ A4 W7 z
想确定一下
" ]) e0 U1 g9 q谢谢!
