3 }' T# H1 r) K) K. \' p( ebreed [dogs dog]
+ q6 Y$ G, C" m3 \! ?breed [cats cat]
1 j5 T/ v! o# N. Q8 wbreed [cows cow]( F& W; w/ _% s" Y4 {
% Y% K- v3 ~* ?$ t6 }- O
to setup: y" {$ T2 X: m* d) Q0 ~
clear-all, x6 ^( a0 ?) r& w0 v ~& w. C7 W
set-default-shape dogs "dog"
, K2 |; I. `: f, R; q8 V set-default-shape cats "cat" P' O6 j; |7 K1 Z) R
set-default-shape cows "cow": i- y/ M1 P( u+ }
ask patch 0 1 [ sprout-dogs 1 ]" V5 S v5 Z# k

ask patch 0 -1 [ sprout-cows 1 ]
3 d+ T( G! t+ a; R8 |7 Iend
_) o% Q) ?# `" F

- s9 C$ `6 X8 \! [: _8 h* T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：
# G$ c+ ^& N& Derror while observer running SET-DEFAULT-SHAPE in procedure SETUP
0 ]; H3 v4 D1 O+ h( a8 E# P"dog" is not a currently defined turtle shape
/ l: d; k* w2 F0 _. D(halted running of setup)
4 N) E- ^$ n0 o* D/ h7 ^( z# n. o2 O' `3 f4 s3 |
' N' c; p A+ w4 T! q我用的版本是4.0.4 请大虾们指教下。thanks！ |
