    in General Support

    Posted · Edited by youyi1314

    Hi , 

     

    May i know what should i change in clif.c in r17690?

    here is cashshop_buy from r17690 clif.c

    /// Request to buy item(s) from cash shop (CZ_PC_BUY_CASH_POINT_ITEM).
/// 0288 <name id>.W <amount>.W
/// 0288 <name id>.W <amount>.W <kafra points>.L (PACKETVER >= 20070711)
/// 0288 <packet len>.W <kafra points>.L <count>.W { <amount>.W <name id>.W }.4B*count (PACKETVER >= 20100803)
/// 0848 <packet len>.W <count>.W <packet len>.W <kafra points>.L <count>.W { <amount>.W <name id>.W <tab>.W }.6B*count (PACKETVER >= 20130000)
void clif_parse_cashshop_buy(int fd, struct map_session_data *sd){

    int fail = 0;
    struct s_packet_db* info;
    int cmd = RFIFOW(fd,0);

    nullpo_retv(sd);

    info = &packet_db[sd->packet_ver][cmd];

    if( sd->state.trading || !sd->npc_shopid )
        fail = 1;
    else {
// #if PACKETVER < 20101116
#if PACKETVER < 20120410
        short nameid = RFIFOW(fd,info->pos[0]);
        short amount = RFIFOW(fd,info->pos[1]);
        int points   = RFIFOL(fd,info->pos[2]);

        fail = npc_cashshop_buy(sd, nameid, amount, points);
        clif_cashshop_ack(sd,fail);
#else
        int s_itl = (cmd==0x848)?10:4; //item _list size (depend on cmd even for 2013+)
        int len    = RFIFOW(fd,info->pos[0]);
        int points = RFIFOL(fd,info->pos[1]);
        int count  = RFIFOW(fd,info->pos[2]);
        unsigned short* item_list = (unsigned short*)RFIFOP(fd,info->pos[3]);

        if( len < 10 || len != 10 + count * s_itl){
            ShowWarning("Player %u sent incorrect cash shop buy packet (len %u:%u)!\n", sd->status.char_id, len, 10 + count * s_itl);
            return;
        }
        if(cmd==0x848){
            cashshop_buylist( sd, points, count, item_list);
        } else {
            fail = npc_cashshop_buylist(sd,points,count,item_list);
        }
#endif
    }
    clif_cashshop_ack(sd,fail);
} 

     

    This is what my map server show:

    [Warning]: Player 150000 sent incorrect cash shop buy packet (len 20:10)!
