# 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).
