Since 99% of you cheat sellers are idiots and use strcmps to identify weapons here is the proper way to do it. int __stdcall Client_s::iGetWeaponID ( C_BaseCombatWeapon *pBaseCombatWeapon ) { int iWeaponID; if ( g_iGameID == CSS || g_iGameID == DoDS ) { __asm

void DrawCrosshair( int r, int g, int b, int a, int style ) { int centerX = sScreenSize.m_iWidth / 2; int centerY = sScreenSize.m_iHeight / 2; switch(style) { case 1: //crosshair dot in middle FillRGBA(centerX - 14, centerY, 9, 1,r,g,b,a); // left FillRGBA(centerX +5, centerY,...

Some people may have trouble finding this address, as it's not referenced directly. Here's the pattern for CSS: //GetBonePosition BYTE GetBonePositionPattern = { 0x56, 0x6A, 0x00, 0x8B, 0xF1, 0xE8, '?', '?', '?', '?', 0x8B, 0x4C, 0x24, 0x08, 0x51, 0x8B, 0xC8, 0xE8, '?', '?', '?', '?',...

Very simple.... but some people may need this, or want to do this if you wish to make your hack inject-able at any time, i.e already in game. DWORD dwGlobals; PBYTE pbMov_Address = ( PBYTE )0x200D01A2; pbMov_Address = &pbMov_Address; vMemCopy( (void*)&dwGlobals, pbMov_Address, 4 ); ...

I'm not sure if this is posted here in some other thread or not, it's pretty simple tho. void DrawHealthBar(int team, int x, int y, int health) { float l; float r=0,g=255,b=0; g = health*2.55; r = 255-g;

i decided to try and create something kind of new :) struct Local_Stats{ int headshots; int kills; int deaths; float ratio; }; Local_Stats player_stats;

I was bored, so i came up with the following, its just a raw patch, so i didnt bother writing a hook for it, even though it would be very easy. "engine.dll" 0117B1F0 /$ 8B4C24 04 MOV ECX,DWORD PTR SS: // void Cmd_ExecuteString (char *text, cmd_source_t src) This will fix the "kill"...

i needed to bypass consistency because my hook modified the material vars, and the next round it wouldnt let you join if the hack was still on :P so instead of setting the materials to default ( ghey ) it was pretty simple using some help from fellow coders around here and another one i made...

3 Easy Steps 1. class CHUDHandler : public IGameEventListener2 2. void CHUDHandler::FireGameEvent( IGameEvent *event ) { gBaseAPI.LogtoFile( "%s", event->GetName() ); }

Okay this is one is extremly simple and maybe even obsolete. However here is comes! first we need to know we can Zoom and just like in the previous version of HL2 we can do this via the fov. pLocalPlayer->SetFOV(pLocalPlayer, gCvars.zoom->getFloat() * 5, 0.2f); this would allow us to zoom via...

you need to hook the CViewRender::WriteSaveGameScreenshot method void CViewRender::WriteSaveGameScreenshot( const char *pFilename ) { //unhook here or stop drawing g_pViewRender->WriteSaveGameScreenshot( pFilename ); //rehook or w/e } Credits: Tetsuo

here is a screeny... :) you need to hook : void CHudDeathNotice::FireGameEvent( KeyValues * event) which is located at 0x24068870 (if you want to detour) or you can patch the vmt at 0x24268B50 if you don't know how to use this method check the SDK ( death.cpp )

Azorbix posted how to do this, without the use of the engine, but seen as iam a engine guy my self :) here you go. First of all, you need a pointer to the "IClientMode" class, when you have this, replace Pointer+0x44 (KeyInput) with your own function. ...

Long story short, HL2 uses PeekMessage(A) for messages (as opposed to GetMessage). in tier0.dll it is linked into the dll, so only a detour (DetourFunc :evolved: ) or an IAT patch will let you hook it, hooking GetProcAddress won't help. using WindowsXP sp1 (my version) the detour size is...

Didnt see this posted, so here goes: 1.) Get a ICvar Pointer, you should know how. 2.) Set up the cvar you wana set: I did this in every HudUpdate, for the cvar "r_3dsky" ConVar *xSKY = cvar->FindVar("r_3dsky"); if( xSKY ) {

this is a stripped down version of IMessageChars::GetStringLength, all this does is get the width and height of text, its useful for console stuff like making a editline cursor void GetStringLength( vgui::HFont hCustomFont, int *width, int *height, const char *fmt, ... ) { va_list...

Here is my basic Entity ESP. Its a bit crappy in case of stripping, but I think its ok: static void DrawEntEsp() { char nbuf; for(int i=33; i < 1024; i++) { IClientEntity *pEnt = NULL; pEnt = pClientEntity->GetClientEntity(i);

Add your own ColorPrintf func if you want to print stuff with different colors or maybe add color format tags to change the color of different parts of the text using gameconsole->ColorPrintf. One note, IsVisible should work, but I didn't get around to testing it. :P Also, I like using pointers...
