模拟时
     obj.move(pos1);
1 T: k( a+ w% h" H( R这句老出错，但不知错在哪 ，请教高手~~~
还有就是装卸站transferstation 的methods初始程序看不懂，
i : integer)
-- @ : waiting Target
9 c+ T& }8 s$ O* y-- ? : TransferStation
" `# p9 P3 j  D5 Y% yis
do
# A' G# T9 a- P0 P- b/ e if i = 1 then
  -- before starting the transfer to the TransferStation
; T& g7 \5 w9 r3 [" V( X  -- parts/target are ready
elseif i = 2 then
  -- before parts leaving the TransferStation
3 ~8 c# e; ]. J end;
end;
: @5 L: I+ I$ P4 f如果要设置有条件的卸载，当物件属性integer满足一定数量条件时卸载，应该如何编写？
