User talk:Iritscen

About your edits of Main Page, they're quite welcome, but:

Normally you're supposed to make "proposals" in Talk:Main_Page

I also think that the main page shouldn't be an exhaustive list.

It was already too long to start with: it needs to be lighter.

Typically, this can be done with a tabulated layout.

Oh, and don't copy one page to another location - move it.

Who here was involved with that effort to hack multiplayer into Oni?

Memory search: Alloc, Kumo, typhen (leader) and me.

Programs: typhen (Onyx/OnyxPatcher), neonew (OniHook)

How was the multiplayer actually supposed to get implemented into Oni?

Overwrite the memory at runtime.

How much was accomplished?

Some memory findings (pointers, player/enemy values, ...). (All?) results are stored here (Used program: TSearch).

What were the obstacles?

Working in the memory in general

Find the pointers (because the pointer position varies from OS to OS and from level to level).

Time (as usual).

typhen stopped his efforts on the project in August of 2005 for real life (girlfriend).

Kumo contributed some pseudonetcode in C++ that was supposed to interface with Onyx.

Alloc's OniTrainer implemented most of the gathered knowledge as the project went.

(OniTrainer had no network component, but it was a good tool for experimentation.)

The problem with TSearching was with all the big dynamically allocated structures.

It was a rather crazy idea to figure out those structures without disassembling...

I think the project started in April/May 2005, so it spanned the summer of 2005.

neonew's OniHook was totally independent of Onyx, so it's another project, sorta.

I'm not sure whether neonew disassembled Oni's engine in order to do the hooking.

A fair amount of Oni's engine has been disassembled since, by both SFeLi and Neo.

The structures responsible for the "game state" and "character state" are known.

Some history:

typhen came up with the project in December of 2004. The first steps in the memory were made with RAMCheat. In January of 2005 typhen found the (great) program TSearch and the real memory search began. In April of 2005 geyser joined the Oni community and two or three weeks later the Ikonboard-based Oni forum crashed. (Because of too many verbose postings by him. :p *just kidding* ;-)

Unfortunately Harry never made this forum available as an archive.

The crash in April 2005 was supposedly due to me posting over a bad connection, which corrupted the database.

My impression is that the actual project started in May 2005 and thus is largely covered on the after-crash forum.

That's where you can see typhen and Kumo exchanging pseudonetcode, typhen and me talking about sync philosophy...

Thanks for the info, guys. And sorry for being something of a jerk yesterday, geyser. Now, you said that the structures for game state and character state are now known -- are you referring to runtime variables? I don't see where those are documented in the wiki, unless this sort of page covers that information. Is that whole structure just loaded into memory to be worked with at runtime, and do we know where in memory to look for it, or is that where the process became difficult, due to that whole "dynamically allocated" structure that you mentioned? --Iritscen 16:42, 15 February 2008 (CET)

"And sorry for being something of a jerk yesterday, geyser." Sigh. I just don't understand why you avoid gathering first-hand knowledge.

Since you have that much free time, why not really come to terms with the object you want to provide accurate documentation for? Sigh.

I must say you still post and edit a wee bit too compulsively (a hyperactive kind of hyperdedication), and with not enough second sight.

Sure, the wiki needs regular editors, but you pretty much "jumped on it like an oversexed hippo" (C) Bungie. Hope it'll wear off somehow.

^_^

The disassembled engine is only documented in private databases, and we do not plan to publish those in any foreseeable future.

The "game state" is a huge chunk of data holding various runtime variables and structured objects (other, big chunks of data).

In particular, the game state structure holds a dynamically allocated array of character objects, each with a character state.

The character state holds various runtime variables specific to a given character, much more than the static game content.

Dynamical allocation means that the space required for the structures is not part of the EXE; it's requested at runtime.

Depending on the history prior to the allocation, the dynamically allocated space may end up at a different location.

The ONCC has little to do with "character state". In fact, the character state holds a mere link to the current ONCC.

Chapters and added value

Flipping through the stuff as I updated the page layout, I was really impressed with the quality of some of the "added value".

Keep up the good work, dude. I'm sure the chapter pages will grow (just a little bit) to be brilliant appetizers for all the rest.
