Osprey doesn't fire trigger targets

[SamVanheer]

The Osprey doesn't fire its trigger targets, which are targets fired when a specific NPC condition is met such as taking damage, dying, etc.

To fix this, apply the following changes:
Uncomment this line:

halflife/dlls/osprey.cpp

Line 67 in c7240b9

// int TakeDamage( entvars_t* pevInflictor, entvars_t* pevAttacker, float flDamage, int bitsDamageType );

After this line:

halflife/dlls/osprey.cpp

Line 69 in c7240b9

void ShowDamage( void );

Add this:

void Update();

After this line:

halflife/dlls/osprey.cpp

Line 160 in c7240b9

pev->health = 400;

Add:

pev->max_health = pev->health;

Replace these lines:

halflife/dlls/osprey.cpp

Line 344 in c7240b9

ShowDamage( );

halflife/dlls/osprey.cpp

Line 408 in c7240b9

ShowDamage( );

halflife/dlls/osprey.cpp

Line 554 in c7240b9

ShowDamage( );

With:

Update();

After this line:

halflife/dlls/osprey.cpp

Line 525 in c7240b9

pev->takedamage = DAMAGE_NO;

Add this:

pev->deadflag = DEAD_DYING;

After this line:

halflife/dlls/osprey.cpp

Line 764 in c7240b9

}

Add this:

void COsprey::Update()
{
	//Look around so AI triggers work.
	Look(4092);

	//Listen for sounds so AI triggers work.
	Listen();

	ShowDamage();
	FCheckAITrigger();
}

int COsprey::TakeDamage(entvars_t* pevInflictor, entvars_t* pevAttacker, float flDamage, int bitsDamageType)
{
	//Set enemy to last attacker.
	//Ospreys are not capable of fighting so they'll get angry at whatever shoots at them, not whatever looks like an enemy.
	m_hEnemy = Instance(pevAttacker);

	//It's on now!
	m_MonsterState = MONSTERSTATE_COMBAT;

	return CBaseMonster::TakeDamage(pevInflictor, pevAttacker, flDamage, bitsDamageType);
}

These changes have the following effects:

• Setting max_health enables the 50% damage condition to work properly.
• Setting deadflag to DEAD_DYING enables the Death condition to work properly.
• The Update method handles showing damage, and now looks around the level which updates condition bits that track whether the Osprey can see enemies or not, which handles the See player * conditions. The look distance is the same as that of the Apache, and covers virtually the entire level. It also listens for sounds, which handles the Hear * conditions. Finally, it evaluates the condition to see if it needs firing.
• TakeDamage stores off the last attacker as the Osprey's enemy so the See Player, Mad at player condition works properly. It also sets the Osprey's state to combat so the See Player, not in combat condition works properly.
