Since EQ is now F2P, I spent some time collecting data from Live for Mercenaries. There does not seem to be too many packets related to Mercs. Below is what I have figured out for mercenary packet structures. Hopefully I can get time to test some of this and maybe implement some basic handling for these packets, but I figured it would be good to post in case I don't get time to do that soon.
Mercenary Packet Structures:
Code:
// Currently unused, but may be good to have
enum MercStance
{
MercPassive = 1,
MercBalanced = 2,
MercEfficient = 3,
MercReactive = 4,
MercAggressive = 5,
MercAssist = 6,
MercBurn = 7,
MercEfficient = 8,
MercBurnAE = 9
};
// [OPCode: 0x27ac] On Live as of April 2 2012 [Server->Client]
struct MercenarySellList_Struct {
int32 MercTypeCount; // Seen 2 - Iterations of MercCategory_Struct
MercCategory_Struct Categories[0]; // From dbstr_us.txt - Apprentice (330000100), Journeyman (330000200), Master (330000300)
int32 MercCount; // Seen 24 - Iterations of MercCategory_Struct
MercenaryInfo_Struct Mercs[0]; // Data for individual mercenaries in the Merchant List
};
struct MercCategory_Struct {
int32 Category; // From dbstr_us.txt - Apprentice (330000100), Journeyman (330000200), Master (330000300)
};
// Used for Mercenary Merchant Lists and for Hired Mercenary Info Updates
struct MercenaryInfo_Struct {
int32 MercID; // ID unique to each type of mercenary (probably a DB id) - (if 1, do not send MercData_Struct - No merc hired)
MercData_Struct MercData[0]; // Data for individual mercenaries - Not populated if no merc is hired
};

These are the opcodes that appear to be directly Mercenary related:
0x6537 Server->Client - Some kinda merc info update. Much smaller with no merc
0x0327 Client->Server - Labelled OP_MercenaryDataResponse in EQExtractor2 (size 0)
0x2ef8 Client->Server - Request dismiss merc (size 0)
0x495d Server->Client - Some merc status update from server - Maybe response to 0x4c6c
0x1a79 Client->Server - Requesting to suspend merc
0x2528 Server->Client - Response to suspend merc
0x4c6c Client->Server - Some kind of merc status change request from client - Examples:
24 00 00 00 01 00 00 00 - Zoning in
01 00 00 00 01 00 00 00 - Dismiss merc
05 00 00 00 01 00 00 00 - Right after purchasing merc
05 00 00 00 00 00 00 00 - Setting merc to passive
05 00 00 00 01 00 00 00 - Setting merc back to balanced
00 00 00 00 ff ff ff ff - Zoning in with no merc
01 00 00 00 01 00 00 00 - Right after previous update of zoning in with no merc
Using Mercenary Merchant:
0x4dd9 Client->Server - Right clicking merchant request
0x27ac Server->Client - Merc merchant response
0x3887 Server->Client - After merchant response
0x5e78 Client->Server - Request to view merc info while browsing merchant?
90 01 00 00 01 00 00 00 46 22 00 00 00 6e e4 03
0x5e78 Server->Client - Server response to 0x5e78
06 00 00 00
0x528f Server->Client - Seen after purchasing merc and when camping
0x6942 Server->Client - Response after purchasing merc - Purchase approval response?
I have a ton more data than I am showing here, but I don't want to post it all until I can organize it a bit more. I will post the rest of the structs for the above lists when I have time. At least the more complex structs should be in pretty good shape from the ones I posted above. The rest are all really small (16 bytes or less).
