Packet help

barnett81 · Dec 5, 2006

I am working on the storage code atm. I have the packet 7ad but I don't know how to get the contents of the packet. I am a good Java Programmer, but never did anything with packets. Does anyone have a way of logging the packets?

Here is a bit of storage information for you... First is a log of a few packets for it and the second is a basic storage function only allows you to open storage as of right now...

Code:

open storage
[3]<<7ad- 00
[3]>>7ad- 01 00

deposit bamboo spear from slot 2 inventory to slot 1 storage
[3]<<7ae- 00 0d 28 14 00 46 c4 00 00

sweet thanks a lot, I'll try to finish it today.

Caali · Dec 5, 2006

lol, you dont need to.
Since I'm quitting rose now (i didnt code for a month or so) and I'm going over to coding my own 3D-MMORPG with some friends, im releasing more and more parts of my code here. later, ill release all my source, it has everything the svn has,

Code:

+ full clan system (except clan skills&points)
+ custom clan images (upload and download)
+ AoE skills
+ learning and lvling skills
+ non-attacking mob movement
+ full drop table
+ private shops almost 100% done, only selling an item to a shop doesnt work yet, but its almost done, quitted when i was coding this =P (its pretty easy to finish it though)
+ party chat
+ clan chat
+ buddy system 100% working
+ party system has some coded things, not done though, but better than the svns one
+ dance scrolls
+ private shop and clan info visibility at pakSpawnChar
+ some starts to the arrow/bullet packet, its working, but buggy
+ many more useful gm commands
+ saving respawn point
+ going back to saved point / current field
+ a function to read out unknown packets fully
+ a MUCH faster and smoother server, its running almost 3 times faster than the svn's one (at least at my comp)
+ ammos are decreased when attacking with an ammo weapon
+ tons of bugfixes and improvements
+ muuuchh more i cant remember

Custom Tools:
+ STB2SQL converter, reads a whole stb file and puts it to your MySQL db
+ NewsEditor for news page
+ my very much better database
+ i have the full sourcecode for 100% implementing TriggerVFS.dll (for game data files)
+ some starts of a launcher coded in Borland C++ Builder 6, including lua scripts for updating etc, not complete working though

Well, after that big list, lemme release my storage code...

DROP TABLE IF EXISTS `storage`;

in the account table, add this:

ALTER TABLE `accounts` 
ADD `storage_zuly` INT UNSIGNED NOT NULL DEFAULT '0',
ADD `platinum` INT UNSIGNED NOT NULL DEFAULT '0';

Do with it what you want, but dont remove my credits.

FYI:
It is possible that some variables are wrong, its because i almost rewrote my database structure and my server structure, thats why its so much smoother and faster now. You'll have to correct them, unless you are gonna wait for me to release the rest of my source.

P.S.:
Guys, have fun with it.

lol, now you tell me. I was about 75% done. That was a big waste of time. I could have been working on homework. lol. Thanks Caali.

The nGage · Dec 5, 2006

+ full clan system (except clan skills&points)
+ custom clan images (upload and download)
+ AoE skills
+ learning and lvling skills
+ non-attacking mob movement
+ full drop table
+ private shops almost 100% done, only selling an item to a shop doesnt work yet, but its almost done, quitted when i was coding this =P (its pretty easy to finish it though)
+ party chat
+ clan chat
+ buddy system 100% working
+ party system has some coded things, not done though, but better than the svns one
+ dance scrolls
+ private shop and clan info visibility at pakSpawnChar
+ some starts to the arrow/bullet packet, its working, but buggy
+ many more useful gm commands
+ saving respawn point
+ going back to saved point / current field
+ a function to read out unknown packets fully
+ a MUCH faster and smoother server, its running almost 3 times faster than the svn's one (at least at my comp)
+ ammos are decreased when attacking with an ammo weapon
+ tons of bugfixes and improvements
+ muuuchh more i cant remember

OMFG Caali i'm sooooo impressed!

well, this packet is damn easy

it took me about 30min to code all that ****, including understanding what which byte means =P

e.g. , clan system is MUCH more

@nGage: thats not much, only about a month... (1,5 weeks for getting and understanding the code, the rest for getting&understanding packets, coding takes like some minutes...)

Yeah thats about how long i've been working on it too. But I'm also watching Scrubs. I fixed some things in your code and will post it on the SVN (with credits to you). Kudos.

Killerbee(NL) · Dec 5, 2006

can't you teach us how to use packets?

Caali · Dec 6, 2006

there is nothing to teach.

it requires

1) Knowledge of C++
2) A brain & logical thinking.

[no_offense_,_but]
when i read your posts, it seems to me you have neither 1) nor 2), so you should nvm...

if you're reading books, as i said thousands of times, start with eaiser projects.

Killerbee(NL) · Dec 6, 2006
