还有就是装卸站transferstation 的methods初始程序看不懂，
i : integer)
3 @+ y% g7 j5 ~; \0 I/ s-- @ : waiting Target
-- ? : TransferStation
is
do
if i = 1 then
  -- before starting the transfer to the TransferStation
  -- parts/target are ready
elseif i = 2 then
0 J8 R  L0 z1 O  -- before parts leaving the TransferStation
8 d* S+ b7 r! c; |8 n end;
/ o% S9 V6 W4 X2 ~. O$ a' Kend;
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？
