EQ Patch 5-22-08

[uRit1u2CBBA=]

Looks like some opcodes got moved around. I get zone and GPS, but no spawns.

I wish I had the time to figure out how to do those :)

[ieatacid]

I think it's mostly the spawn struct (opcodes are unchanged as far as I can tell). It's now variable in length and may take some time to figure out how the client is unpacking it.

[Fatal]

Any word on the damage?

[Razzle]

I have started looking at what they changed. Looks like they added a new opcode for the initial send of the zone spawns. Basically splitting up the old spawn info. I might actually start working on writing some code, if my wife doesn't have like 12 more projects for me this weekend. I really hate summer sometimes.

I have the spawnStruct mostly done, I just need to figure out a few bit fields. The name strings (name, surname, title, etc) are variable length now (zero-terminated, length of the name) and I'm still not sure how to handle that.

[Razzle]

I was looking at how to handle variable lenghts. In everquest.h, the struct specialMessageStruct, has what appears to be two sections of message text, that may be variable lengths. I am not sure if that is what it is doing, with them sepearated by a uint32_t.

I was going to play with the structure formating, to see if it already handles it. Looking at NetStream::readText in netstream.h, it looks like it will go through the stream searching for a null terminated text stream, if you set the length to 0, as listed like in the specialMessageStruct.

Here it is. The bitfield stuff at the top was a pain.

Does any new code need to be changed to get it to work?

I replaced the existing structure definition with what you had above, and it didn't change anything.

Thanks :)

[ieatacid]

Yeah, additional changes will be necessary to handle the variable size of struct.

[Adept]

Nice work.

[purple]

Look at how the guild info packet is handled. There are stream classes that are used to pull stuff off the wire when it is variable length. I made it handle bit streams when the new movement packets went in last fall.

[ieatacid]

Nice, I never even noticed those :)

That should make life easier.
