The client will respond to this by sending a response to the original request just as if the user had hit ESC to cancel targeting.

Notes
Only 3D clients send this packet. Server and client packet.
Unsure as of when, 2D client added this ability also.

Client asks for name of object with ID x. Server has to reply with ID + name. Client automatically knows names of items. Hence it only asks only for NPC/Player names nearby, but shows bars of items plus NPCs.

Client request has 7 bytes, server-reply 37. Triggered by Crtl + Shift.

Notes
Server requests assist version via server side version of this packet, client replies with client side version of packet.

Notes
Subcommand 1: Server Sent. This sets up stack on the client and whenever it moves, it takes the top value from this stack and uses it. (key1 starts at the top, key6 at the bottom)

Subcommand 2: Server Sent. This key is added to the top of the stack. In other words, it's the one that will be used next. Basically, the other 5 only get used when the client is sending moves faster than the server is responding.

Subcommand 4: Server Sent.

Subcommand 5: Client Sent.

Subcommand 6: Sent by both. Contains subcommands for 0x6 for the party system. Be sure you check the packet listing good before attempting these.

Subcommand 8: Server Sent.

Subcommand a: Read above. Client Sent.

Subcommand b: Client Sent once at login of character.

Subcommand c: Client Sent when they close their status bar.

Subcommand 13: Client Sent.

Subcommand 14: Server Sent. TextID is broken into two decimal parts:
stringID / 1000: intloc fileID
stringID % 1000: text index

So, say you want the 123rd text entry of intloc06, the stringID would be 6123. Newer clients without the intloc files, that use single Cliloc files, use the math ID - 3000000 for the ID to send.

BYTE[1] direction
BYTE[1] sequence number
BYTE[4] fastwalk prevention key


Subcommand Build
N/A


Notes
Sequence number starts at 0, after a reset. However, if 255 is reached, the next seq # is 1, not 0.

Fastwalk prevention notes: each 0x02 pops the top element from fastwalk key stack. (0xbf sub1 init. fastwalk stack, 0xbf sub2 pushes an element to stack)
If stack is empty key value is 0. (-> never set keys to 0 in 0xbf sub 1/2)
Because client sometimes sends bursts of 0x02's DON'T check for a certain top stack value.
The only safe way to detect fastwalk: push a key after EACH 0x21, 0x22, (=send 0xbf sub 2) check in 0x02 for stack emptyness.

If empty -> fastwalk alert.
Note that actual key values are irrelevant. (just don't use 0)
Of course without perfect 0x02/0x21/0x22 synch (serverside) it's useless to use fastwalk detection.
Last but not least: fastwalk detection adds 9 bytes per step and player !

Direction Notes:
0x00 - North
0x01 - Northeast
0x02 - East
0x03 - Southeast
0x04 - South
0x05 - Southwest
0x06 - West
0x07 - Northwest

Running affects the Direction number also. When running, it is Direction|0x80. Therefore direction becomes 0x80, 0x81, and so on.

Be very careful how to handle this odd "bursts" server side, neither always process, nor always skipping is correct.

Notes
Only works for player played by client.
x,y,z have to be in range (check packet 0xc8 for range details) from players current location. Packet has to be sent 19 times or more in a row, otherwise it does not do anything, relatively speaking, on OSI servers.

If all this satisfied it does a path finding like action for the character.

location of destination is displayed above players head (cannot be disabled).

Notes
For pre 2.0.7 clients Type is always < 0xc0. Uox based emus convert post 2.0.7 data of this packet to pre 2.0.7 data if Type >=0xc0.

(different view of it)
If Mode&0xc0 then there are keywords (from speech.mul) present.
Keywords:
The first 12 bits = the number of keywords present. The keywords are included right after this, each one is 12 bits also.
The keywords are padded to the closest byte. For example, if there are 2 keywords, it will take up 5 bytes. 12bits for the number, and 12 bits for each keyword. 12+12+12=36. Which will be padded 4 bits to 40 bits or 5 bytes.

The various types of text is as follows:
0x00 - Normal

BYTE[1] temperature


Subcommand Build
N/A


Notes
Types: 0x00 - "It starts to rain", 0x01 - "A fierce storm approaches.", 0x02 - "It begins to snow", 0x03 - "A storm is brewing.", 0xFF - None (turns off sound effects), 0xFE (no effect?? Set temperature?)


Maximum number of weather effects on screen is 70.

If it is raining, you can add snow by setting the num to the num of rain currently going, plus the number of snow you want.

Weather messages are only displayed when weather starts.


With Old clients the weather will end automatically after 6 minutes.
With New clients ( unsure when changed ) the weather will end automatically after 10 minutes.

To avoid the weather to end automatically you have to resend the weather packet during that time.

If you resend weather packet 1 time it will reset the 6 or 10 minute timer and start it over again.

If you resend the weather packet more than once it will reset the time and start a timer with doubled time no matter how many times you resend, it always just doubled the timer in my tests.


You can totally end weather (to display a new message) by teleporting. I think it's either the 0x78 or 0x20 messages that reset it, havent checked it though.

Flags list:
0x01: unknown
0x02: send config/req logout (IGR?, overwrite configuration button?)
0x04: single character (siege - limit 1 character/account)
0x08: enable npcpopup/context menus
0x10: limit character slots?
0x20: enable common AOS features (tooltip thing/fight system book, but not AOS monsters/map/skills, necromancer/paladin classes)
0x40: 6th character slot
0x80: samurai and ninja classes
0x100: elven race
0x200: KR support flag1 ?
0x400: send UO3D client type (client will send 0xE1 packet)
0x800: unknown
0x1000: 7th character slot, only 2D client
0x2000: unknown (SA?)
0x4000: new movement packets 0xF0 -> 0xF2
0x8000: unlock new felucca areas

Flags can be combined as literals to view. Such as to have NPC Popup Menus AND Common AOS Features, send as 0x28, not 0x8 plus 0x20 form.
Another example: elven race, samurai classes and AOS will be 0x1A0.

0x8000 flag is used for unlocking new Felucca factions areas, note that you have to use "_x" versions of map/statics if you want to move through new areas.

Since 7.0.13.0 City Name and Building Name have length of 32 chars, also added city x,y,z,map,cliloc description and BYTE[4] always 0 to city structure.

Notes
In gump packets, and with any EMU (POL for sure) the "ID" is the # of the script's PID that fired the gump. This can be used via specific 0xBF packets to send the ID to the client to force closing of the gump from the server. When this is done, the client Auto Responds as if it had "exited" the menu normally so the serverside script will handle it as such.

Older notes (not sure which are correct!):

if (MSB not set)
Bit# 1 T2A upgrade, enables chatbutton
Bit# 2 enables LBR update. (of course LBR installation is required)(plays MP3 instead of midis, 2D LBR client shows new LBR monsters,...)
if (MSB set)
Bit# 3 T2A upgrade, enables chatbutton
Bit# 4 enables LBR update
Bit#5 enables AOS update (Aos monsters/map (AOS installation required for that) , AOS skills/necro/paladin/fight book stuff - works for ALL clients 4.0 and above)


Examples:
ML: B980FB
AOS-7AV: B9803B
AOS: B9801B
LBR: B90003


Custom housing uses these flags to enable some parts.

for FeatureMask check floors.txt, roofs.txt etc in client folder

FeatureMask 0 = AOS ( flag 0x10 )
FeatureMask 64 = SE ( flag 0x40 )
FeatureMask 128 = ML ( flag 0x80 )
FeatureMask 512 = 9th age ( flag 0x200 )
FeatureMash 65536 = SA ( flag 0x10000 )

Notes
Client versions >= 7.0.0.0 is sending this instead of the old Object Information packet 0x1A

Seems like 0x1A is still working with item graphics <= 0x3FFF but OSI uses this now to send ALL.
