Fast Dynamic NetVar Offset and Hook System

[Herp Derpinstine]

This should work on any Source Engine game. Enjoy.



Could be better but I wrote and tested this in under 15 minutes.

Call g_NetVarMgr.Initialize() when you want your NetVars to be found.

Call GetOffset() of the NetVar Manager Variable to get the Offset of the stored NetVar.

Call GetOriginalProxy() of the NetVar Manager Variable to get and/or run the Original Proxy of the stored NetVar.
Mostly just used inside of your NetVar Proxy Hook.


EXPLANATION

For the sake of this explanation lets say you already have a Dynamic NetVar Offset System and that it is only 1 function.
Something along the lines of GetOffset(DATATABLE, NETVAR) that scans the Client Classes and returns the Offset.

m_Local: 237
m_vecPunchAngle: 505
m_hConstraintEntity: 1601
m_iHealth: 1960
m_lifeState: 3219
m_iObserverMode: 3565
m_hObserverTarget: 3912
m_fFlags: 4257
m_iTeamNum: 4453
m_hOwnerEntity: 4653
m_hActiveWeapon: 4942
m_iClip1: 5215
m_iClip2: 5497
m_flNextPrimaryAttack: 5784
m_flNextSecondaryAttack: 6068
m_nTickBase: 6388
m_vecOrigin: 6596
m_vecViewOffset[0]: 6875
m_vecViewOffset[1]: 7174
m_vecViewOffset[2]: 7474

Above is a chart of NetVars that I used in order with a 1 function Offset System.
Next to the NetVars in the chart is the approximate total number of for statement loops it has to go through before getting the NetVar.

IE: ( Loops_Before_GetOffset_Function_Call + Loops_to_NetVar )

Using the IE above the total loop count will always be the largest loop count displayed.

An approximate total of 7474 loops to get all 20 of those NetVars. A bit excessive even when you get all NetVars only once.

However, when I use the same NetVars in the same order with my system this is what it displays.

m_Local: 237
m_vecPunchAngle: 248
m_hConstraintEntity: 323
m_iHealth: 339
m_lifeState: 340
m_iObserverMode: 345
m_hObserverTarget: 346
m_fFlags: 344
m_iTeamNum: 361
m_hOwnerEntity: 365
m_hActiveWeapon: 491
m_iClip1: 624
m_iClip2: 625
m_flNextPrimaryAttack: 630
m_flNextSecondaryAttack: 631
m_nTickBase: 315
m_vecOrigin: 354
m_vecViewOffset[0]: 278
m_vecViewOffset[1]: 279
m_vecViewOffset[2]: 280

An approximate total of 631 loops to get all 20 NetVars.
6843 loops less than before to do exactly the same thing.

The loop count of my system may seem a little wierd because my system organizes the NetVars by DataTable in the Que.

Also the first NetVar you add will either have a loop count equal to or a little more than the 1 function Offset System
due to the Que's vector size.

If you see a mistake or something that could be improved let me know. I am always open to helpful ideas.

this is way bigger than it needs to be, and have you ever heard of recursion? i dont know what i expected from you sperginstine

why not use c++11 and do recursive calls to get all netvars in like 10 lines or is that too hard for you?

Lmao. Can you read? I wrote this in under 15 minutes. You think it will be good?
Hey jackass. I'll still take your advice even though you hate me because no matter how you act to me your still my bae .

It would've took less time to just call the function again instead of just adding more for loops

[Flying Gooby]

Sadly, no one here knows what this is useful for, apart from a few people.

It would've taken you infinitely less time to do proper recursion, you probably could've had this done in 5 minutes tops if you used proper recursion, not to mention strcmp is extremely slow (which is why SSE exists...) and all the loops you use significantly impact performance.

[ExiledStyles]

this is not useful to anyone, neither is this made by you and the original code has been posted everywhere already
if you had more than one brain cell you do full data iteration (m_MoveType and others) but we all know if it's not public you don't have it

LMAO. I would like you to provide proof I didn't write this.
Also why should I care what you think?
I have been on a drug and alcohol bender for the past few days so the only one I will tolerate abuse from is my bae and my unicorn room-mate named Charlie. <3

funny how you didn't pay attention to anything i said, should be enough proof to show you don't have the brain cells to write something like this
you and all the talentless queers on here have to post random pasted code because constantly making unfunny anime jokes isn't enough
