示例1: TargetAim

// Get a vector giving the direction this ship should aim in in order to do
// maximum damaged to a target at the given position with its non-turret,
// non-homing weapons. If the ship has no non-homing weapons, this just
// returns the direction to the target.
Point AI::TargetAim(const Ship &ship)
{
	Point result;
	shared_ptr<const Ship> target = ship.GetTargetShip();
	if(!target)
		return result;
	
	for(const Armament::Weapon &weapon : ship.Weapons())
	{
		const Outfit *outfit = weapon.GetOutfit();
		if(!outfit || weapon.IsHoming() || weapon.IsTurret())
			continue;
		
		Point start = ship.Position() + ship.Facing().Rotate(weapon.GetPoint());
		Point p = target->Position() - start + ship.GetPersonality().Confusion();
		Point v = target->Velocity() - ship.Velocity();
		double steps = Armament::RendevousTime(p, v, outfit->Velocity());
		if(!(steps == steps))
			continue;
		
		steps = min(steps, outfit->TotalLifetime());
		p += steps * v;
		
		double damage = outfit->ShieldDamage() + outfit->HullDamage();
		result += p.Unit() * damage;
	}
	
	if(!result)
		return target->Position() - ship.Position();
	return result;

示例2: RendezvousTime

// Fire this weapon. If it is a turret, it automatically points toward
// the given ship's target. If the weapon requires ammunition, it will
// be subtracted from the given ship.
void Armament::Weapon::Fire(Ship &ship, list<Projectile> &projectiles, list<Effect> &effects)
{
	// Since this is only called internally by Armament (no one else has non-
	// const access), assume Armament checked that this is a valid call.
	Angle aim = ship.Facing();
	
	// Get projectiles to start at the right position. They are drawn at an
	// offset of (.5 * velocity) and that velocity includes the velocity of the
	// ship that fired them.
	Point start = ship.Position() + aim.Rotate(point) - .5 * ship.Velocity();
	
	shared_ptr<const Ship> target = ship.GetTargetShip();
	// If you are boarding your target, do not fire on it.
	if(ship.IsBoarding() || ship.Commands().Has(Command::BOARD))
		target.reset();
	
	if(!isTurret || !target || target->GetSystem() != ship.GetSystem())
		aim += angle;
	else
	{
		Point p = target->Position() - start + ship.GetPersonality().Confusion();
		Point v = target->Velocity() - ship.Velocity();
		double steps = RendezvousTime(p, v, outfit->Velocity());
		
		// Special case: RendezvousTime() may return NaN. But in that case, this
		// comparison will return false.
		if(!(steps < outfit->TotalLifetime()))
			steps = outfit->TotalLifetime();
		
		p += steps * v;
		
		aim = Angle(TO_DEG * atan2(p.X(), -p.Y()));
	}
	
	projectiles.emplace_back(ship, start, aim, outfit);
	if(outfit->WeaponSound())
		Audio::Play(outfit->WeaponSound(), start);
	double force = outfit->FiringForce();
	if(force)
		ship.ApplyForce(aim.Unit() * -force);
	
	for(const auto &eit : outfit->FireEffects())
		for(int i = 0; i < eit.second; ++i)
		{
			effects.push_back(*eit.first);
			effects.back().Place(start, ship.Velocity(), aim);
		}
	
	Fire(ship);

		this->angle += Angle::Random(inaccuracy) - Angle::Random(inaccuracy);
	
	velocity += this->angle.Unit() * weapon->Velocity();

		this->angle += Angle::Random(inaccuracy) - Angle::Random(inaccuracy);
	
	velocity += this->angle.Unit() * (weapon->Velocity() + Random::Real() * weapon->RandomVelocity());
	
	// If a random lifetime is specified, add a random amount up to that amount.
	if(weapon->RandomLifetime())
