FireBullets() is a method which handles damage for any hitscan weapon. It is passed FireBulletsInfo_t as its required parameter, which describes the bullet in question.

Members

info

Name given to the FireBulletsInfo struct that is passed into method.

pAmmoDef

Stores the ammo definition in a pointer.

flActualDamage

Used to store the actual damage to be done to entity.

iPlayerDamage

If it's deemed we are damaging a player, this is used instead of flActualDamage

tr

TraceLine used when the weapon fired. tr.m_pEnt is the entity that was intersected e.g. NPC, crate, wall.

Damage

This is the core function where the damage is done to the entity. DispatchTraceAttack is passed dmgInfo which contains the attacker, damage value and damage type.

CTakeDamageInfo dmgInfo( this, pAttacker, flActualDamage, nActualDamageType );
CalculateBulletDamageForce( &dmgInfo, info.m_iAmmoType, vecDir, tr.endpos );
dmgInfo.ScaleDamageForce( info.m_flDamageForceScale );
dmgInfo.SetAmmoType( info.m_iAmmoType );
tr.m_pEnt->DispatchTraceAttack( dmgInfo, vecDir, &tr );
