Description: Suck 'em dry!

This tutorial will show you how to create new damage type for the Egon. This damage type, Vampire, will suck the victim�s life and add it to yours.

First we are going to define the new damage type.
Open cbase.h and find

	CODE
	#define DMG_MORTAR (1 << 23)

and add this

	CODE
	#define DMG_VAMPIRE (1 << 24) // Hit by vampire

Save cbase.h.

Open client.cpp and in void ClientPrecache( void ) add

	CODE
	PRECACHE_SOUND("ambience/biotone.wav");

Save client.cpp.

Next open player.cpp. In void CBasePlayer :: TraceAttack( entvars_t *pevAttacker, float flDamage, Vector vecDir, TraceResult *ptr, int bitsDamageType) after the switch statement add

	CODE
	if(bitsDamageType == DMG_VAMPIRE) { bool bSound = false; int iDamage = (int)flDamage; for(int i = 0; i < iDamage; i++) { if(!bSound) { bSound = true; EMIT_SOUND(ENT(pev), CHAN_BODY, "ambience/biotone.wav", 1, ATTN_NORM); } if(pevAttacker->health < pevAttacker->max_health) { pevAttacker->health++; } else if(pevAttacker->armorvalue < 100.00) { pevAttacker->armorvalue++; } } }

This will add the amount of damage you cause to your health until it is 100% and then to your armor until it is 100%. After that you will just cause damage. The victim will hear a sound when hit.

In the function int CBasePlayer :: TakeDamage( entvars_t *pevInflictor, entvars_t *pevAttacker, float flDamage, int bitsDamageType ) find

	CODE
	if (bitsDamage & DMG_SHOCK) { bitsDamage &= ~DMG_SHOCK; ffound = TRUE; }

and add

	CODE
	if (bitsDamage & DMG_ VAMPIRE) { bitsDamage &= ~ DMG_ VAMPIRE; ffound = TRUE; }

Save player.cpp.

Open egon.cpp and find class CEgon : public CBasePlayerWeapon add

	CODE
	void SecondaryAttack(void);

Now create the Secondary Attack function, after void CEgon::PrimaryAttack( void ):

	CODE
	void CEgon::SecondaryAttack(void) { m_fireMode = FIRE_NARROW; Attack(); }

The secondary attack fires a narrow beam.

In void CEgon::Fire( const Vector &vecOrigSrc, const Vector &vecDir ) find

	CODE
	case FIRE_NARROW: if ( pev->dmgtime < gpGlobals->time ) { // Narrow mode only does damage to the entity it hits ClearMultiDamage(); if (pEntity->pev->takedamage) { pEntity->TraceAttack( m_pPlayer->pev, gSkillData.plrDmgEgonNarrow, vecDir, &tr, DMG_ENERGYBEAM ); }

and replace

	CODE
	pEntity->TraceAttack( m_pPlayer->pev, gSkillData.plrDmgEgonNarrow, vecDir, &tr, DMG_ENERGYBEAM );

with

	CODE
	pEntity->TraceAttack( m_pPlayer->pev, gSkillData.plrDmgEgonNarrow, vecDir, &tr, DMG_VAMPIRE );

That�s all folks. You can e-mail me at scobra@ananzi.co.za for comments and questions.

how can i make the beam just like the primary fire, but red instead of purple?

if you mean primary fire then place it under class CEgon::PrimaryAttack(void)
