模拟时
1 m, E4 [' ?" r. U6 h% |" h8 g* @     obj.move(pos1);
5 a0 M) o+ W: Y/ n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，
i : integer)
- ?: u6 [5 v" F+ }- h8 q-- @ : waiting Target
-- ? : TransferStation
is
9 i3 q% ^% ~5 S. v4 p6 Y0 p( X; fdo
# P1 m! T8 u9 \5 z$ z$ [ if i = 1 then
3 y; p9 X2 w7 [& |2 o  -- before starting the transfer to the TransferStation
( s( y; r4 ]% d; E/ K" O  -- parts/target are ready
- A" K/ V' X" b elseif i = 2 then
  -- before parts leaving the TransferStation
end;
( y: E' o/ ]7 `5 D" ~9 C- q3 M& zend;
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？
