还有就是装卸站transferstation 的methods初始程序看不懂，
i : integer)
-- @ : waiting Target
-- ? : TransferStation
: X' D- `# r- f/ E: eis
) w$ y8 j1 E: kdo
( Q. q; {# F4 S! L5 [2 `" i8 p& u if i = 1 then
6 {8 P( t+ g0 x" q- a9 W  -- before starting the transfer to the TransferStation
  -- parts/target are ready
elseif i = 2 then
  -- before parts leaving the TransferStation
7 r8 y' M4 ^7 W  J/ X! k end;
; V1 X2 i5 p* H: ?end;
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？
