我的程序如下：
$ q- t' S. F. dbreed [dogs dog]
/ _ e4 b/ ?7 h; xbreed [cats cat]
! ~4 R& ~) U2 H* ]8 N9 Wbreed [cows cow]
* y9 c& J4 D3 h* M
" a$ b. n" p! qto setup
' x% J; k# b+ e clear-all
: N( ~& n' ^3 l; B% h set-default-shape dogs "dog". h; o/ z3 o }/ A& `- ?
set-default-shape cats "cat"# C# h" {$ O' v1 R1 [$ y3 n e' @- y
set-default-shape cows "cow"2 p) \6 j( l+ o- Z2 M# E
ask patch 0 1 [ sprout-dogs 1 ]
: R. n" Q) T5 q" s; } ask patch 0 0 [ sprout-cats 1 ]
3 Q- |8 |+ s3 _0 f- h6 g3 z ask patch 0 -1 [ sprout-cows 1 ]) A' c X; u6 `, I2 \
end w5 n" |3 k) b( N! v
6 N u# I- b7 O1 \( V3 B
, K9 [2 I. E6 H2 m* x D6 d% N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：
# A6 ?0 {3 t' V1 ]+ g4 H+ Zerror while observer running SET-DEFAULT-SHAPE in procedure SETUP& h# X+ C( ?' U& m, y3 d+ {2 }
"dog" is not a currently defined turtle shape
! J' l/ ]; l+ c(halted running of setup)
7 {! `0 p x8 J+ `3 m* C$ j7 z/ B
" a! Y3 T6 u ^
我用的版本是4.0.4 请大虾们指教下。thanks！ |
