Ok so....
1) I make new file options.properties ( because i havent it)
2) I copy to this file :
# GeoData options:
# 0 = GeoData and PathFinding OFF (default)
# 1 = GeoData used to check Line Of Sight (LOS) targetting and
# L2Playable movement. You need to download files for data/geodata folder.
# Monsters can pass walls but not aggro through them.
# 2 = Full GeoData enabled, CURRENTLY FOR TESTING ONLY. Includes PathFinding
# (requires also /data/pathnode files) and all character moves go
# through geodata checks (if a mob passes a wall, pathing is wrong).
GeoData = 2
#[true]Loads GeoData buffer's content into physical memory.
#[false] Does not necessarily imply that the GeoData buffer's content is not resident in physical memory.
ForceGeodata = true
3) Now i dont know thats is all.....? I havent write any command to another files? e.g. general.properties?
Thank u man
