Hi,
I offer very improved GeoEngine & PathFinding (pf files're generating by server if pf region misses). The Engine's much faster than l2j one but takes more memory (i think about ~100Mb) caused by special maps format . Maps're edited manually, fixed a lot of issues. I can add also a tool to convert old l2j/l2off maps to improved ones.
Improvements:
+ full-checked movement
+ pathfinding for players/npcs or just players (config)
+ really fast way to find a currect path (like for me works better then official)
+ less CPU usage (but cost more memory)
+ for Interlude I can add DoorModificator - changes geo maps in fly when doors open/close
So if U're interesed or have problems with ur current geodata (for example: movement on new oly arenas or vision check) send me PM/mail here.
If U've ur own project or any custom I can implament the engine in ur source code (ofc If U're a adv dev I'll send just source/diff for current revision of l2j).
