I don't know whether the Dev's worked out the formula for calculating the offsets for version 2 EQGs, but I searched and couldn't find anything relevant after this thread.
I've been messing about trying to get OpenEQ to load version 2 EQGs, and came across this old thread:
http://www.eqemulator.net/forums/arc...p/t-21615.html
Based on that, I knocked together the following bit of Python to calculate the offsets (excuse my Python, but I'm new at it :) ):
Code:
import struct, posixfile, socket, zlib, pdb, sys
for eqgfilename in ["broodlands", "guildhall", "guildlobby", "harbingers", "stillmoona", "stillmoonb", "thenest", "thundercrest"]:
filenames = []
files = []
eqgfile = file(eqgfilename + '.eqg', 'rb')
block = eqgfile.read(12)
(offset, magic, unknown) = struct.unpack('L4sL', block)
eqgfile.seek(offset, posixfile.SEEK_SET)
block = eqgfile.read(4)
dir_count = struct.unpack('I', block)
for i in range(0, dir_count[0]):
block = eqgfile.read(12)
(crc, fileoffset, filesize) = struct.unpack('LLL', block)
if crc == 0x61580AC9:
CurrentPos = eqgfile.tell()
eqgfile.seek(fileoffset, posixfile.SEEK_SET)
InflatedLength = 0
uncompressed = ''
while InflatedLength < filesize:
block = eqgfile.read(8)
(deflen, inflen) = struct.unpack('LL', block)
block = eqgfile.read(deflen)
uncompressed = uncompressed + zlib.decompress(block)
InflatedLength = InflatedLength + inflen
eqgfile.seek(CurrentPos, posixfile.SEEK_SET)
fncount = struct.unpack('L', uncompressed[0:4])
pos = 4
for j in range(0, fncount[0]):
fnlen = struct.unpack('L', uncompressed[pos:pos+4])
fmt = str(fnlen[0]) + 's'
fname = struct.unpack(fmt, uncompressed[pos+4:pos+4+fnlen[0]])
fname = fname[0].strip('\x00')
if fname[len(fname)-4:len(fname)] == '.ter':
wantedfile = fname
filenames.append(fname)
pos = pos + 4 + fnlen[0]
else:
files.append((eqgfile.tell() - 12, fileoffset))
for i in range(dir_count[0] - 2, 0, -1):
for j in range(0, i):
if files[j][1] > files[j+1][1]:
tmp = files[j]
files[j] = files[j+1]
files[j+1] = tmp
for a in range(0, dir_count[0]-1):
if filenames[a] == wantedfile:
eqgfile.seek(files[a][0], posixfile.SEEK_SET)
block = eqgfile.read(12)
(crc, fileoffset, filesize) = struct.unpack('LLL', block)
eqgfile.seek(files[a][1], posixfile.SEEK_SET)
break
uncompressed = ''
inf = 0
while inf < filesize:
block = eqgfile.read(8)
(deflen, inflen) = struct.unpack('LL', block)
block = eqgfile.read(deflen)
uncompressed = uncompressed + zlib.decompress(block)
inf = inf + inflen
(magic, version, list_len, obj_count, vert_count, tri_count) = struct.unpack('4sLLLLL', uncompressed[0:24])
ter_tmp = list_len
pos = 24
while pos < ter_tmp:
strlen = 0
while uncompressed[pos+strlen] != chr(0):
strlen = strlen + 1
fmt = str(strlen) + 's'
(strvar) = struct.unpack(fmt, uncompressed[pos:pos+strlen])
pos = pos + strlen+1
strlen = 0
while uncompressed[pos+strlen] != chr(0):
strlen = strlen + 1
fmt = str(strlen) + 's'
(strval) = struct.unpack(fmt, uncompressed[pos:pos+strlen])
pos = pos + strlen+1
pos = 24 + list_len
for b in range(0, obj_count):
(index, name_offset, another_name_offset, property_count) = struct.unpack('LLLL', uncompressed[pos: pos+16])
pos = pos + 16
for a in range(0, property_count):
pos = pos + 12
print "Offset for EQG Zone %-20s (TER: %-22s) is %8X" % (eqgfilename, wantedfile, pos)
For the EQG zones hardcoded in the currently downloadable version of azone, it spits out the same offsets:
Code:
Offset for EQG Zone broodlands (TER: ter_broodlands.ter ) is 382B7
Offset for EQG Zone guildhall (TER: ter_guildhall.ter ) is 307E
Offset for EQG Zone guildlobby (TER: ter_guildlobby.ter ) is 41A3
Offset for EQG Zone harbingers (TER: ter_harbingers.ter ) is 1178
Offset for EQG Zone stillmoona (TER: ter_main.ter ) is 71948
Offset for EQG Zone stillmoonb (TER: ter_easterntemple.ter ) is E33E
Offset for EQG Zone thenest (TER: ter_abyss01.ter ) is CA244
Offset for EQG Zone thundercrest (TER: ter_stormtower01.ter ) is 6222C
