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! C) J2 ^7 \ i7 v4 ^
其中有一段如下, u, @& G2 [4 e! \7 b
ask turtles with [ infected? = true ]
4 ]+ k! _" U* A( c' I我原本以为这句会回传『所有』infected? = true 的 turtle: q' T6 [+ ?% W# I! Y! J" a
但看结果似乎不是这样。8 I8 l7 X9 m" Z3 o# q& N
" C; i1 \+ m4 ?假设所有符合条件的有 5 笔
1 h# K& b* @9 H! y7 c7 V有时候回传 1 笔,有时回传 3 笔,是不固定的
- c/ d, Z3 W1 f7 \4 D7 @回头查语法定义: S, F6 J9 n$ X, G4 {# i: r
with 3 g; k) E7 i' p+ ^2 B7 p
agentset with [reporter]" ~( B/ b% o5 S" H
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.
5 R- z ?/ R' n" }5 @% ^它只说回传 agents satisfying the given condition
: ]5 X3 B+ L& `- O( |& G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 ?
+ O* M7 R+ ^, y
7 [$ l) B0 {7 j想确定一下6 Z: @0 P. V6 x" O
谢谢!
