我的程序如下：
, L, z2 w+ \; B: M; Wbreed [dogs dog]! k. M4 T! G0 `5 E$ |
breed [cats cat]
4 ^3 R' Z; c9 P9 _& @( T% y6 _' bbreed [cows cow]
~: Q# w" G J% g4 C" S4 Z k
+ ^. x y! T1 C' t7 K& L+ h: Nto setup
" `4 E( G$ H I. V( x0 u# Q, @ clear-all# P4 e `: n7 p9 x" U
set-default-shape dogs "dog"
j% |( I5 \: o2 K) l5 j9 v set-default-shape cats "cat"+ t5 a) S- B$ @9 ] e
set-default-shape cows "cow"
. p3 ]" o% H: d5 r ask patch 0 1 [ sprout-dogs 1 ]
( ^( X1 P5 T/ r0 I7 u ask patch 0 0 [ sprout-cats 1 ]7 b: b# |5 h& W: o2 `7 C' q* Q

end( ?: H' r: u7 G: p* W, v) D
& P/ f7 u$ T5 i3 a3 |; d4 r+ Y' n3 e& R2 v
这个是netlogo自带模型库里的模型中的程序，我新建文件再将其输入却提示错误：
" i6 V% S! H7 Q. Jerror while observer running SET-DEFAULT-SHAPE in procedure SETUP
& J# V7 p! |9 N2 n( D8 j"dog" is not a currently defined turtle shape# |) |2 Y# t# L' M
(halted running of setup)4 P9 i6 J c) _9 A- Q- ?$ q
8 \8 ?/ X! e- z `. n& F- Y* P, [
. j. N! O) `7 ^7 y
我用的版本是4.0.4 请大虾们指教下。thanks！ |
