我的程序如下：
8 ?/ J- d+ T" Fbreed [dogs dog]$ ] {) ?7 g3 s- X. w& ~
breed [cats cat]- }- p. u- P% C3 ^: }& {& d
breed [cows cow]" q6 }8 }% A- v/ }5 ~

. V* K- z; ?$ |2 l6 \ ask patch 0 1 [ sprout-dogs 1 ]. A+ l4 B7 v7 }! i

# _! M7 y9 I0 p2 zend, R* u' q& c, | v9 P

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：2 t; m, z* R( h, O1 n
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
( m# d0 R+ G, d: q: `# e n1 c* }"dog" is not a currently defined turtle shape& }& J2 M2 H( V8 D
(halted running of setup)
, T1 ]: k0 U$ `: a

我用的版本是4.0.4 请大虾们指教下。thanks！ |
