Possibly, I have not tried this myself. Does the code in this PR get you the monster/NPC names?

I've just coded it blindly without ever running it so idk. I've assumed how it should be basing on the one that was getting the names of items

run it with mon instead of send

Also, there probably will be same error for guessing the correct IDs (if wont find prolly will crash). They vary, some +- be found here https://tibia.fandom.com/wiki/Creature_IDs for testing.

I imagine, it should be possible to obtain all names of monsters/npcs. If you have possibility to try it out, that would be awesome. I wanted to try it out for quite for over half a year now, but didn't had 'right circumstances'
If you can add me at discord @elkolorado

in the Extract app you can use the --monsters parameter and you can also use --npcs

i saw it, however it recevies packets from map data. What i wanted to achieve is first sending the lookat monster packet (as if you are looking at creature with given id), and then receiving data from it (so the name of it would be received), given it could be possible to obtain all names bounded to all creature ids that exist. Given how lookat was used to obtain item all names of item ids despite clearly not being near those items, the creatures/npcs could be also possible, basing on how similar it works ingame.

It would be great to have some information on the creatures, besides the name

the names itself would be awesome also, given the ceratin topics resolving around mysteries

I tried running the program against the latest Tibia client, but I couldn't get past the login screen. Note that this is unrelated to your change; the code in the master branch doesn't work with the newest Tibia client.

The program crashes here:

Two messages get through, with these buffer values (hexadecimal):
Message 1: 01 00 00 FF FF 3F 00 00 (read := 1)
Message 2: 00 00 00 FF FF 3F 00 00 (read := 7)

The third value of the read variable is 0, and we hit the exception.

I unfortunately don't have the time (nor perhaps the know-how) to troubleshoot this further, but I am happy to accept PR's if anyone else can fix this.

it might be related to newest client, however there is legacy client here; https://static.tibia.com/download/Tibia_Setup_Legacy.exe maybe u could try with that?
