In the end of 2015 I experimented with l2tower, 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)
2) - how to make it work
3) .
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) - we parse packets and save it to disk here, some commands init here too.
2)
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.
