还有就是装卸站transferstation 的methods初始程序看不懂，
i : integer)
2 b. @+ `: R' o-- @ : waiting Target
-- ? : TransferStation
is
do
1 K0 f5 l3 Y8 w" J& n if i = 1 then
1 ^. b- x! F+ ?* M+ ~  -- before starting the transfer to the TransferStation
4 {) d8 w2 k8 a5 |. B  -- parts/target are ready
elseif i = 2 then
  -- before parts leaving the TransferStation
: ~8 d* J2 r  D2 u) Z8 @ end;
) m2 F% A- ?* ^end;
) k9 b: d3 o" M3 C. K; M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？
