我的程序如下：
# r n' w: H. E, D% {breed [dogs dog]7 S5 ~2 r# F6 Z( p, b0 x: o
breed [cats cat]1 {4 X, `) e4 n+ v5 O+ U
breed [cows cow]# M& l1 ^) U4 ?% ?3 B

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：$ m$ l& ^; Y" l
error while observer running SET-DEFAULT-SHAPE in procedure SETUP% ?: l8 m) h: N( P1 b
"dog" is not a currently defined turtle shape

我用的版本是4.0.4 请大虾们指教下。thanks！ |
