如何制作装物品的袋子
相信不少MOD中都有大量的可压缩物品，即不用保存属性的物品，想神符、宝石之类的东西。虽然这些东西每个的长度仅为14BYTE，但是多了也占据不少空间、占用的服务器资源、还有宝贵的箱子资源。所以用一个属性记录有什么可压缩物品以及他的数量，那么就可以大量的节省资源。下面的//make the client to show the item in the itemstat. //让显示物品袋子储存的东西，增加使用28号显示。 //enter point //ebp ; + XX [to] [ebp] //[esp+2c] ; ~~~~ 6FAF24BE 83F8 1C cmp eax,1C ;改上限
