Title: Questions about packets/client
Post by: mrk on April 27, 2022, 05:00:35 PM

How do you know which packet/format the client expects in a given request?

For example, I'm trying to complete RequestNewHennaCompose in BattleChronicle. I have already enabled the packet debug suggested at: https://l2jmobius.org/forum/index.php?topic=7416

What method/tool do you suggest to know which packet (format) to send to the client, or which packet the client expects?

Thank you very much. Very didactic. Where/How do I get this first part of the code?
