Hi guys, first of all I would like to thank all the forum guys, who answer stupid nooby questions, to all who shared there master crafted lua scripts and special thanks to the L2Tower creators.
In the end of 2015 I experimented with tower, packets and market in Giran and finally I get some time to open source results and write step by step tutorial how to use it.

Some links:
1) Youtube video - short demo. Sorry for sound quality and my bad English
2) Step-by-step tutorial - how to make it work
3) Github repo.

Few words about L2Tower here.

L2Tower is used to scan private stores(In my case - High Five private server) in towns, you can see realization right here:
1) PacketLogger plugin - we parse packets and save it to disk here, some commands init here too.
2) roaming.lua
Is the main roaming script, which controls all other aspects of roaming - moving in the towns, teleporting, path creation based on nearest private stores etc.

All the other stuff of this project is to process and show this scanned data to visitors.

I hope you guys will find this share useful, cheers.
