Counter-Strike SDK

Counter-Strike SDK
- last updated : 2 apr 2010

The purpose is obviously not to provide a full working and compilable project
but only showing the content of some functions to know more on some CS specificities,
understanding the flow of some features, extracting useful datas thus creating better plugins
which should be more finely, intelligently, and efficiently coded.

So, from now I'm starting to release there as many function as I can gradually as time passes.
If people want to help, they are welcomed, though you should be aware it requires a lot of times.

As side notes I don't know much C/C++ so there will be probably some typos and sometimes
you will see pawn syntax. Unless it must be fixed, don't bother me with details.

I've started recently, don't expect to see all the functions at once.
I will try to keep one post by class, so I can explain things if need,
like the offsets related to the function, or from where is called such function.

~~EDIT: Now the project has been moved at : https://github.com/Arkshine/CSSDK~~
EDIT2: Another project by s1lentq, more complete at: https://github.com/s1lentq/ReGameDLL_CS. Consider checking this one instead.

Re: Counter-Strike SDK

Nice job!

EDIT: In player.cpp, lines 231 and 241, you're assigning instead of comparing:

Re: Counter-Strike SDK

Thanks, it will be fixed for the next version.

Arkshine, Nice job.

In multiplay_gamerules.cpp, lines 238, 245, 252 and 259, you're using sprintf incorrectly (I'm not sure what you meant, but it was probably a ClientPrint)
In the same file, line 268, there's an incomplete statement:

I think Arkshine went crazy doing this :P

Good job, very useful.

Re: Counter-Strike SDK

Well, you may right because there is still so much to post. :mrgreen:

@seta00 : Thanks, it's fixed. About sprintf, it's actually ALERT().

Damn. It sucks putting directly the link, it will open each time a tab/windows. But no choice if I keep to release there. :/

Re: Counter-Strike SDK

You should create some small page atleast on wiki

Re: Counter-Strike SDK

Later. When there will too much data I will migrate all on the wiki. But right now it's only the beginning and I prefer sharing here, seeing feedbacks, adjusting the contents etc..

Re: Counter-Strike SDK

are there any m_CollisionGroup like offset in HL1 ? Iam thinkin a NoBlock plugin like this for HL1 -> http://forums.alliedmods.net/showthread.php?p=746250

:shock::shock::shock:

By the way, how exactly are you doing this?

Re: Counter-Strike SDK

IDA pro + HLSDK + a lot of times ( because you need to check, recheck, searching, guessing, switching between linux/windows IDA output etc.. IDA is a motherfucker sometimes you have to be careful :/ )

@Dr.G : No idea right now.

Actually it's the same as HLSDK, just checked.

What you need would be probably :

CBasePlayer::Observer_CheckProperties()
CBasePlayer::Observer_CheckTarget()
CBasePlayer::Observer_FindNextPlayer()
CBasePlayer::Observer_HandleButtons()
CBasePlayer::Observer_IsValidTarget()
CBasePlayer::Observer_SetMode()

What do you search ?

I wonder if Observer stands for spectator player or just hltv.
I need spectator.

Re: Counter-Strike SDK

Something like :

Code:

void CBasePlayer::Observer_HandleButtons()
{
    if ( m_flNextObserverInput <= gpGlobals->time )
    {
        int mode;
       
        if ( m_afButtonPressed & IN_JUMP )
        {
            switch ( pev->iuser1 )
            {
                case 1, 2 : mode = 4;
                case 3    : mode = 5;
                case 4    : mode = 3;
                case 5    : mode = 6;
                default   : mode = m_fObserverAutoDirector ? 1 : 2;
            }
         
            Observer_SetMode( mode );
        }
       
        if ( m_afButtonPressed & IN_ATTACK )
        {
            Observer_FindNextPlayer( 0, 0 );
        }
 
        else if ( m_afButtonPressed & IN_ATTACK2 )
        {
            Observer_FindNextPlayer( 1, 0 );
        }
       
        m_flNextObserverInput = gpGlobals->time + 0.2;
    }
}

I don't know how to name the offsets. You ask now you have to give names. :mrgreen:

Re: Counter-Strike SDK

Thanks.

FYI and from hlsdk:

m_flOffsetPlayer100 -> m_flNextObserverInput

I found observer.cpp only on ricochet & dmc

Re: Counter-Strike SDK

Nice catch. :mrgreen:

Will take a look too.

Re: Counter-Strike SDK

Code:

else if ( m_afButtonPressed & IN_FORWARD )

Shoud rather be IN_ATTACK2

Observer_FindNextPlayer( 1, 0 )
First param could be something like Next/Previous, and i think that 2nd param could be about allowed players, like team specific param.

Re: Counter-Strike SDK

It's weird because I see for both linux/window IDA output "& 8" ; but it makes sens it should be IN_ATTACK2. ( EDIT : Ah I think I know why )

About the last param, the type is a string, it seems to be an optional param to search directly a player by its name. Looking at the function I see a check done in a loop with this param and m_hObserverTarget->pev->netname.

Anyway it should look now like :

Code:

#define OBS_NONE          0
#define OBS_CHASE_LOCKED  1
#define OBS_CHASE_FREE    2
#define OBS_ROAMING       3        
#define OBS_IN_EYE        4
#define OBS_MAP_FREE      5
#define OBS_MAP_CHASE     6

void CBasePlayer::Observer_HandleButtons()
{
    if ( m_flNextObserverInput > gpGlobals->time )
    {
        return;
    }

    if ( m_afButtonPressed & IN_JUMP )
    {
        int mode;
        
        switch ( pev->iuser1 )
        {
            case OBS_CHASE_LOCKED : 
            case OBS_CHASE_FREE   : mode = OBS_IN_EYE;
            case OBS_IN_EYE       : mode = OBS_ROAMING;
            case OBS_ROAMING      : mode = OBS_MAP_FREE;
            case OBS_MAP_FREE     : mode = OBS_MAP_CHASE;
            default               : mode = m_fObserverAutoDirector ? OBS_CHASE_LOCKED : OBS_CHASE_FREE;
        }
     
        Observer_SetMode( mode );
    }
   
    if ( m_afButtonPressed & IN_ATTACK )
    {
        Observer_FindNextPlayer( FALSE );
    }
    else if ( m_afButtonPressed & IN_ATTACK2 )
    {
        Observer_FindNextPlayer( TRUE );
    }
   
    m_flNextObserverInput = gpGlobals->time + 0.2;
}

Re: Counter-Strike SDK

From cl_dll/hud_spectator.cpp

PHP Code:


		
			
FindNextPlayer( (ButtonPressed & IN_ATTACK2) ? true:false );

I wonder if you, Arkshine, are getting only assembler code with IDA or something else that can help to move it to C.

It was hard to my to understand the structure of the decompiled code.

Re: Counter-Strike SDK

For sure, we can reduce the code like that. I know there are some functions which are taken from the Client and modified on the server like StudioEstimateGait().

I'm not enough crazy to try to decompile from the disassembled code !! :mrgreen: I don't have the knowledge to start ( even though I've read severals asm tutorials ). I'm using a decompiler provided with IDA which greatly help by given a nearly C output. Even with that, it takes a lot of time to understand because the output is often weird and you have to read carefully, following the goto, thinking if the structure is right, filtering between virtual functions, entities data, etc., switching between windows/linux decompiled binary because the output differs and you can have an output more pertinent than the other. For example CBasePlayer::Killed() takes me ~2h ( without counting the time to search what does some things ), though I have to finish one part yet. So, you can imagine without decompiled code it would take so much more time. :)

By the way, I'm thinking to actually try to reproduce a decent SDK with header and such, so I could use Doxygen to generate a documentation system like we can see for metamod. This way it would be better to see the relations and references. I wanted to do that manually but the forum or the wiki suck as hell. I think it's a more appropriate solution instead of posting like I do.

It's the best that way!:)

Re: Counter-Strike SDK

Another way is to start a Google Code project and put all together in SVN to you can upload updates with revision control.
You have code parsing and you can search inside the SVN too so it's very useful.

Re: Counter-Strike SDK

In waiting to have more file and a good structure to use Doxygen, I could use for sure a Google Code project so people could help more easily, especially people knowing very well C/C++ who could fix easily typos/errors and such. Thanks for the suggestions.
