However, the spawn structure appears to have changed internally (even though it's the same size) -- most obviously, the position of the character name has moved. As a result, still no skittles. :)

[Quietdagger]

How would I begin to debug this? I have some programming experience, I just need someone to point me in the right direction...I would love to see if I could help out.

[purple]

I answer that question all the time. The last time I answered it was here (http://www.showeq.net/forums/showthread.php?t=5510).

[Whizzie Wiz]

The most fundemental thing is to have a before-the-change zonelog. With that it seems to be not too hard to figure out the basic OP codes.

As for the skittles, I'm getting there with the basics, got name, surname, race, class, level, bodytype and deity offsets figured out, now trying to figure out how to find the spawnId offset in spawnStruct, since this is the key that holds everything else together...

EDIT: Ok, got that (+0012), now to try and figure out where the location/heading info is and I'd be sorted....

[purple]

The best way to find the spawnId is to consider yourself and find that in the zone.log. This will get your spawnId. Now find your OP_ZoneEntry from the server (which is a spawnStruct for you) and find that spawnId in it. It is at 0012 right now for example.

[Whizzie Wiz]

Thanks :) did it another way, looking for uniqueness in the zone spawns. :D

[Whizzie Wiz]

I'm a bit stumped on the position data. I'm trying to check the position of certain NPCs that shouldn't have moved (i.e. they've had the same x/y/z in all the spawnlog.txt I can find going back a few months) but the location data from pre-patch doesnt seem to be present post-patch. Any ideas?

[purple]

Welcome to the hard part. If you look in player.cpp and spawnshell.cpp, you'll see #if 0 around the debugging code I use to figure out position packet struct changes.

[spack]

I'm shakin' man. Comin' down hard. Need a fix bad. Hey man, got some skittles?

[Whizzie Wiz]

I see from the 5.5.0.0-pre1 release that they swapped the x/y/z components around... nice work spotting how they did that!

[dphantom]

Thanks Purple and whomever else behind the scenes contributed.
