模拟时
3 L+ E3 @1 i' j4 {2 o     obj.move(pos1);
) e! b0 O+ W  }, s4 j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，
5 @7 [, E/ ~- H+ ~0 ]# ]i : integer)
-- @ : waiting Target
-- ? : TransferStation
( C& J) Z. }0 ?7 a3 I- H$ iis
do
( m+ B  r+ [0 i/ r" f  m" n6 | if i = 1 then
  I+ N# d0 z. c, g5 `  C* P  -- before starting the transfer to the TransferStation
0 B. P% R0 q* \7 b; H  -- parts/target are ready
& F$ P8 W, N/ X3 ~1 u elseif i = 2 then
* G0 G) P- b( i3 z; H! f  -- before parts leaving the TransferStation
end;
end;
! v8 e7 ~( }6 q7 o! h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？
