Question How find IInput * input for connect CUserCmd * cmd ?

[mihas404]

Hi guys! How find IInput * input for connect CUserCmd * cmd ?
Console say : input = 0x0

CUserCmd * cmd = input->GetUserCmd(90);

Sorry for the quick question (this hurry)

What game are you talking about?

 

[mihas404]

game counter strike source , i use SDK

 

[NTvalk]

i use SDK

Look in the sdk for functions that use the input structure, and reverse it.

 

[brinkz]

CInput pointer can be found in various functions in IBaseClientDLL

 

[mihas404]

Unfortunately, I'm bad friend with reverse . Not sure what i do this true .

I found in the SDK "class CHLClient: public IBaseClientDLL" it contains a function for example:
virtual void IN_ActivateMouse (void);

I connect to olydbg CSS, open module client.dll and "all referenced text strings". But I can not find there "IN_ActivateMouse"

please kick me in the right direction .

 

[brinkz]

Because it is a function name, not a string. Check how i reversed WorldToScreen and do the same with VClient.

Ok. I tride your tutorial:

1. I find VClient017 in client.dll (in SDK - #define CLIENT_DLL_INTERFACE_VERSION "VClient017" ), and when i take IBaseClientDLL

g_pBaseCDll = (IBaseClientDLL*) clientBase(CLIENT_DLL_INTERFACE_VERSION, NULL);

my console show , what take is good :



2. I see this :



3. I copy 25B89E68 and go in ReClass



What i do wrong ?

For 2:
Try following the PUSH 256A93A0, at that memory region should be the mov of the pointer.

 

[mihas404]

If I understand you correctly, I go to 2B5093A0
I appear here:



I take 2B9AD9B0 and go in ReClass

this again <None> :

and so in the end I was able to take W2S.),

I tried to take the "Input" by your tutorial W2S, but since I'm bad in reverse, I stopped at the last stages ...

in SDK in abstract_class IBaseClientDLL , func № 14 - IN_ActivateMouse()

abstract_class IBaseClientDLL
{
public:
	// Called once when the client DLL is loaded
	virtual int				Init( CreateInterfaceFn appSystemFactory, 
									CreateInterfaceFn physicsFactory,
									CGlobalVarsBase *pGlobals ) = 0;

	virtual void			PostInit() = 0;

	// Called once when the client DLL is being unloaded
	virtual void			Shutdown( void ) = 0;
	
	// Called once the client is initialized to setup client-side replay interface pointers
	virtual bool			ReplayInit( CreateInterfaceFn replayFactory ) = 0;
	virtual bool			ReplayPostInit() = 0;

	// Called at the start of each level change
	virtual void			LevelInitPreEntity( char const* pMapName ) = 0;
	// Called at the start of a new level, after the entities have been received and created
	virtual void			LevelInitPostEntity( ) = 0;
	// Called at the end of a level
	virtual void			LevelShutdown( void ) = 0;

	// Request a pointer to the list of client datatable classes
	virtual ClientClass		*GetAllClasses( void ) = 0;

	// Called once per level to re-initialize any hud element drawing stuff
	virtual int				HudVidInit( void ) = 0;
	// Called by the engine when gathering user input
	virtual void			HudProcessInput( bool bActive ) = 0;
	// Called oncer per frame to allow the hud elements to think
	virtual void			HudUpdate( bool bActive ) = 0;
	// Reset the hud elements to their initial states
	virtual void			HudReset( void ) = 0;
	// Display a hud text message
	virtual void			HudText( const char * message ) = 0;

	// Mouse Input Interfaces
	// Activate the mouse (hides the cursor and locks it to the center of the screen)
	virtual void			IN_ActivateMouse( void ) = 0;
	// Deactivates the mouse (shows the cursor and unlocks it)

IN_ActivateMouse() contains "input"

void CHLClient::IN_ActivateMouse( void )
{
	input->ActivateMouse();
}

i found EDX in CE and go in Olly.

I doubt what to do next:

please explain what's next.
