我的程序如下：
- [$ P+ o! _, G, H7 Ubreed [dogs dog]6 u, E! p" {* {; D( d& d
breed [cats cat]! o- _, F4 B. m8 z8 x
breed [cows cow]+ k9 c; u* r! ]: O6 V
0 q9 O0 j- a$ d0 \! Bto setup( n) ?9 K8 b M7 L9 D
clear-all
- s# r, F3 O6 y% } set-default-shape dogs "dog"
; }" N8 ]3 S& n6 E7 h6 V set-default-shape cats "cat"& _8 c! A- S" E/ _. K0 u, `
set-default-shape cows "cow"
8 W% q* G6 u; { j' O ask patch 0 1 [ sprout-dogs 1 ]
8 F" r( o* a4 d M/ J ask patch 0 0 [ sprout-cats 1 ]
# p, Y- e# X2 _2 h0 f' E ask patch 0 -1 [ sprout-cows 1 ]
" c* Z8 f* X5 l0 ]5 z- a2 T$ gend
9 {+ P, A, q5 X. z. z m9 U
7 J- W1 \/ |5 w$ S; k! R) y2 B# l C- I! E$ x& l# G
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：
" b. @# z9 W ?2 n( ^3 b6 jerror while observer running SET-DEFAULT-SHAPE in procedure SETUP) C, F- ^4 o* G
"dog" is not a currently defined turtle shape
7 O5 r' h( s, V4 R2 f(halted running of setup)
8 W9 _" z9 M# |% M7 e0 [
{1 r- v, ]: K2 r% o0 O
t+ v" m: M/ x# q/ j我用的版本是4.0.4 请大虾们指教下。thanks！ |
