He pax, I think your character list packet is a lil bit wrong.

I think it should be parsed like that:

Code:
[BYTE]		2
[BYTE]		1

[BOOL]		Char slot 1 in use
IF char slot 1 in use
{
	[INT]		ObjectID
	[SHORT]		Length of char name
	[STRING]	Char name
	[BYTE]		Char scale
	[BYTE]		Char level
	[LONG]		ExpOffset
	[SHORT]		Str points
	[SHORT]		Int points
	[SHORT]		Stat points
	[INT]		CurHP
	[INT]		CurMP
	[BYTE]		Num of visible items
	FOREACH visible item
	{
		[INT]		ItemID
	}
}

[BOOL]		Char slot 2 in use
IF char slot 2 in use
{
	...
}

[BOOL]		Char slot 3 in use
IF char slot 3 in use
{
	...
}

That's right :) It's correctly parsed packet :)

I'll give this thread a BUMP after a long long time
Since zeteris didn't share his packets I had to parse everything myself
And because it was my first try and I had ABSOLUTELY no experience with that old clients it took me quite long(just started with it again, today, because I learned some asm)
Because I had to parse the packet myself I had to, ofc parse it completely, and well that's what I did.
There are only two parts left(One is a part of the quests, and the other one is something at the end)

Once I know the structure of the whole packet, I'll release it
Note: I only know how it's parsed not for what the data is used!!
But that's quite easy to find out, if needed

Here goes a Screenshot:

I still spawn at some unknown area and didn't parse the packet with all the char info(hp/mp etc) yet, but this will be done rather fast

This packet was pretty hard tbh

Oh and once my Server is somewhat useable(npc/etc working) I'll release the source code

----------------------------

Another update^_^
Finding out what x/y sectors I need to use, took longer than i thought
a/w
I got it working and understand how it works

realXPos = (xSector - 46)*192 + XOffset/10
realYPos = ((int)ySector/2 - 23)*384 + YOffset/10

BUT

You don't send the ySector to the client!!!
You send (ySector/2) as BYTE, which means that won't be able to get to all odd ySectors(everything after the comma is cut off!)!
How to solve this?
You can't "solve" it
Your yOffset now is valid from 0 to 3840(the xOffset just like it has always been from 0 to 1920)
Example: How to get to ySector 45:44
Let's calculate x first:
x = (45 - 46) * 192 + 0/10 = -192

Now let's try y:
y = (44/2 - 23) * 384 + 0/10
y = (22 - 23) * -384
y = -384

Please not that you can't get to 45:45 directly!! If you want/need to you will have to add 1920 to yOffset, which will put you in the lower left corner of 45:45

That's it i guess

Screenshot(just because i can):

Once more an update(wonder how many posts epvp stacks onto the previous one lol)
I got movement working
Not that it was that hard(but it wasn't easy either!), but it made "exploring" things easier^^
Not too bad for 2 days work

Pretty cool if you can run from ht to dw without teleporting^^

Aaaaaand one more update...
[Only registered and activated users can see links. Click Here To Register...]
Spawning mobs works now
ONLY mobs though and I'm still missing some small parts in the packet

Edit: NPCs are working w/o errors too(some hours already^^; just didn't post here)
oh and Autospawn is in progress
I want this server to be as realistic as possible^_^

--------------------

Day 4: I can now spawn Other players. There are only a few Bytes left in the single spawn packet I need to find out what they are used for

This was easier than I thought

if you fit with swsro files it can be more than awesome and ofcourse I will buy from you for good price because you put effort in this

-and for zeteris , he is only a greedy person like half of community

I won't sell them
it will be open source
And i don't have any server files I can play with
I use olly to parse the packets and examples of up2date sro versions to reconstruct them
I have no packets from old sro versions and had to learn assembler in order to do this now. That's why it took me so long to get started^^(and well I have other things to do as well)

I'll release the first beta version when Autospawn is working(and buying/selling and such basic things)

Oh and I make a documentation of every packet I parse. These will be released as well

great news :D good luck

Sorry to disappoint you, but it is written in C++ xD
I don't use the C++ libraries though(Only chose C++, because I can create classes, else I'd have used C)
Why?

because I hate c++?:D

Well it's not that hard to learn^^
And if you know C#/PHP you should also know C++.
Not that much of a difference imo

yey c++! cant wait for first version. GL with your project

Thanks^_^

I'm working hard on Autospawn now
Some might wonder why I start with this "that early"
Well. They way I do it, multiplayer will require my autospawn system
And I want that to be working very well!
That's why I start that early. It gives me enough time to improve it as the project goes on
Small things can be done all the time, but handling spawns server-wide requires it's time.

It's a bit more complex than some of you may think
I'm pretty sure that my server will use 100MB in idle
But after that the growth per logged in player won't be high(this is just what i think^^; only time will tell though)

btw..if you've got the spawn packets already,then autospawn shouldn't take too long..it's prolly one of the easiest things to do..

It's definitely not the way i do it xD
All mobs/npcs will be created on startup
And Mobs will walk too!(All the time, even if no player is in range; still not sure how I'll do it)
And only objects in range of the player will be spawned and if he get's out of range they will be despawned
