Item packet creation

Well well, I've played a server sided game b4 and I know that we can make a "item creation" I said creation not dupping...thats impossible on server sided games although every1 knows that, but I know a theory that worked on the other game and it really worked at least for some items, but it was a simple game in flash and well Im not used with this whole source code of conquer but if I have some help, maybe we can make a tool that makes lots of items dropping on the ground :D I will explain it later on.

if this is true, it would be nice

it wont work.

Conquer has a Unique ID for every item, so you cant just go "Making" items

Hojo beat me to it. :p

I know that it has a unique ID and that's where is the exploit
to reach that unique id the game must make a combination, it can't just create from nothing... I'll give an example so u can figure out if it can work or not...

First of all u need a good packet tracer so u can search the packets sent and received, then make a test, hit some mobs and kill them until u find a ref item or a meteor(should be anything rare, or otherwise u can mess up the hole thing)Then get those 2 packets( the last one sent to server, that u killed the mob, and the 2 after that, the item on the ground and u picking it up, then compare the 3 packets I dont know if they encrypt the packet but if its encrypted it will be a lot harder coz u will need to open that packet and lookfor the combination inside the packet...but well, if its not the combination should be on the packet try searching for some reasonable numbers just like this XXXXX.2583.XXXX... and the other packet should be anything like XXXX.1291.XXXX if u look carefully u can find out that the second number is half than the first so thats its the combination, and now all u need to do is to look for a mob hit it, and then send a packet with that combination (just like u hit the mob and the the id is 444, so u should send a pcket 222)and when he dies u should get the item. but I dont know if it can work here coz the combination can be oh different ways...

Arcane sounds smart :) I sense a new person with ambition!

Btw, I am really not that good with hex's, so can anybody (cough cough hojo cough cough), approve that this may be true, but personally, i think the chances are slim that the packets would be exactly like he said...

Although i may not post alot, I am well read in the ideas having to do with item creation. I have heard of others trying to figure out such item codes, without prevail. If you can, more power to ya. I think that this subject may be fruitfull, just very difficult as well.
Good Luck

I Imagine the item creation routine is called explicitly by server routines, and its not possible to call it otherwise. I can only think of 4 instances when a NEW item is created.

ex
mine_ore() { createnewitem(); }
buyfromshop() { createnewitem(); }
monster::dies() { createnewitem(); }
quest::complete() { createnewitem(); }

-Mining is done completely server side. We tell the server we have begun to mine, and it does the rest independent of our client.
-Buying from shop, we must have money, and the shop must sell the item we want, we can't fake that
-Killing monsters, we cant fake, because all monsters have a unique ID too.
-I'm not aware of any quests that dont have server side checks.

That would mean, we cannot call the createnewitem() routine without performing one of the standard functions i just mentioned. It means: without server access we can completely rule out the possibility of create new, or duping items. There is no way we can use a packet to create a new item, so follow my advice and give up trying.

to the best of my knowledge, item ids are created randomly

Item IDs are created on a counter.

createitem() {
counter++;
}

You can tell by opening a ginseng of something, where 3 items are created almost at the same time. The IDs are inceremental.

i suggest you not to play with packets, you can get banned for messing around with packets

I remember back in the early days od Diablo II with ingame packetsyou could have quite some fun.
Im almost postive this wont work but it worked in the earley stages of D2.

Send gold drop packets (i forgot all bytes and dwords for all so bare with me P)
then block that packet and change it and it drops what you changed it to.

Like i said im almost shure this is impossible..but at one time it wasnt :P

Well since everybody understood how my ideia should work I'll be more detailed on what Im wondering about coz I know it can be done.
First of all we're not "creating items" we're assigning them to the mobs that we're killing, just like this:
The game engine works almost like on this way:
Im excluding the sold and mined items coz they are assigned on a different way,
But from mobs it should work almost on this kinda way:
Items creation,
Monsters creation
Assigning items to monsters
Spawning monster on map(or screen as u desire)
And well even using a unique ID or random generation for all the routines above, it can?t just throw it to anywhere, coz if it do that it will crash the game, coz if u pay attention u never get a rare item killing on sequence it always come from time to time, or on changing monster type, and here is where we can use the exploit coz even with that unique ID the monster should have it hex normal code on it otherwise the server can?t recognize it as a monster, or the item as an item, and all that we?re doing is just a ?changing? at the item, just say at this way, the monster that has the item is a Robin, and u?re killing a elfape, u dont know where the item is, so better than hunting is bringing the item to u, when u?re sendind the packet with the combination the server should recognize as u?re hitting a monster with a rare item and drop it then a new item is generated and assigned.
I know this can be done, although it must be real hard since the game can use a lot of variations to assign the items to the mobs, but believe it really works this way, otherwise the game shouldnt work properly, i was used to be a game developer and almost all kinda games that ?gives? items to the players works on this way, to give u the item it assign to somwhere first, it can?t make and thow it to anywhere otherwise it would have a malfunction on the entire game engine coz all u should need to do is lag the server and a lot of items would be generated simultaneously colapsing the entire game engine. ;-)

Oh I was almost forgeting about the D2 it still can be done, but it uses encrypted packets so u should be a monster to make it, coz at the last I saw they're where using 128 bits;-)

Back in my Co1 days I always messed around with the ini folders files, and I found you can make a store sell anything you want if you just select the code from another file and replace an item in the store with that item you chose. I never got to far into it, I only made it to where DC would sell clubs and swords and the default arrows.

I'm not a genious and i'm not trying to sound like one, I was just putting in my two quarters is all.
