Remove Head Crab

How to Remove HeadCrab from zombie

in hl2_dll\npc_zombie.cpp look for void CZombie::Spawn( void ) then find this line.

m_fIsHeadless = false;

and simply change it to read this

m_fIsHeadless = true;

Now open hl2_dll\npc_BaseZombie.cpp and change this section to look like this.

//-----------------------------------------------------------------------------
// Purpose: A zombie has taken damage. Determine whether he release his headcrab.
// Output : YES, IMMEDIATE, or SCHEDULED (see HeadcrabRelease_t)
//-----------------------------------------------------------------------------
HeadcrabRelease_t CNPC_BaseZombie::ShouldReleaseHeadcrab( const CTakeDamageInfo &info, float flDamageThreshold )
{
	return ( m_iHealth <= 0 && m_fIsTorso && IsChopped( info ) )?RELEASE_RAGDOLL_SLICED_OFF:RELEASE_NO;
}

Working CS:S Muzzle Flashes without Model Editing

In c_baseanimating.cpp, at line 3024 (after the big switch statement), comment out the code so it looks like this

			if ( iAttachment != -1 && m_Attachments.Count() > iAttachment )
			{
				/*
				GetAttachment( iAttachment+1, attachOrigin, attachAngles );
				int entId = render->GetViewEntity();
				ClientEntityHandle_t hEntity = ClientEntityList().EntIndexToHandle( entId );
				tempents->MuzzleFlash( attachOrigin, attachAngles, atoi( options ), hEntity, bFirstPerson );
				*/
			}

and insert the following code after the comment.

 				if ( input->CAM_IsThirdPerson() )
 				{
 					C_BaseCombatWeapon *pWeapon = GetActiveWeapon();
 					pWeapon->GetAttachment( iAttachment+1, attachOrigin, attachAngles );
 				}
 				else
 				{
 					C_BasePlayer *pPlayer = C_BasePlayer::GetLocalPlayer();
 					CBaseViewModel *vm = pPlayer->GetViewModel();
 					vm->GetAttachment( iAttachment+1, attachOrigin, attachAngles );
 					engine->GetViewAngles( attachAngles );
 				}
 				g_pEffects->MuzzleFlash( attachOrigin, attachAngles, 1.0, MUZZLEFLASH_TYPE_DEFAULT );

Go to fx.cpp, under the statement pParticle->m_vecVelocity.Init(); in FX_MuzzleFlash, place the following code.

		C_BasePlayer *pPlayer = C_BasePlayer::GetLocalPlayer();
		Vector velocity = pPlayer->GetLocalVelocity();
		pParticle->m_vecVelocity += velocity;

Crossbow Bolt going through glass (func_breakable)

Open weapon_crossbow.cpp

In CCrossbowBolt::BoltTouch( CBaseEntity *pOther ) After :

if ( pOther->GetCollisionGroup() == COLLISION_GROUP_BREAKABLE_GLASS )
    return;

Insert the following code :

if(Q_strcmp(pOther->GetClassname(), "func_breakable") == 0)
{
    CBreakable* pOtherEntity =  static_cast<CBreakable*> (pOther);
    if(pOtherEntity->GetMaterialType() == 0)
        return;
}

Ignite Your Ragdolls

In your player's class (CSDKPlayer or CBasePlayer) find the Event_Killed() function. Add this inside of it:

if( info.GetDamageType() & (DMG_BLAST|DMG_BURN) )
{
    if( m_hRagdoll )
    {
        CBaseAnimating *pRagdoll = (CBaseAnimating *)CBaseEntity::Instance(m_hRagdoll);
        if( info.GetDamageType() & (DMG_BURN|DMG_BLAST) )
        {
            pRagdoll->Ignite(45, false, 10 );
        }
    }
}

If you don't have a ragdoll to ignite before that is called, make sure that code is placed after a call to CreateRagdollEntity(). If you're not doing that, add it in right above the if( info.GetDamageType() & (DMG_BLAST|DMG_BURN) ) line.
