还有就是装卸站transferstation 的methods初始程序看不懂，
i : integer)
, h/ S0 H3 C3 b" r) x4 s- S4 M-- @ : waiting Target
' Q9 W  t0 I5 q" |. F& w9 z+ `-- ? : TransferStation
is
- m3 {/ ~2 ?9 }( p# M7 r: ado
' v6 R5 q$ K' v2 L1 S+ Y+ G! _0 z, v if i = 1 then
+ |- @! Q: l) ]* i' }+ H  -- before starting the transfer to the TransferStation
  -- parts/target are ready
elseif i = 2 then
' q0 [0 V0 H4 q. V. ?7 K  -- before parts leaving the TransferStation
end;
end;
" e! I& s: O2 `; M# M3 D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？
