示例1:
// Fire an anti-missile. Returns true if the missile should be killed.
bool Armament::Weapon::FireAntiMissile(Ship &ship, const Projectile &projectile, list<Effect> &effects)
{
int strength = outfit->AntiMissile();
if(!strength)
return false;
double range = outfit->Velocity();
// Check if the missile is in range.
Point start = ship.Position() + ship.Facing().Rotate(point);
Point offset = projectile.Position() - start;
if(offset.Length() > range)
return false;
// Figure out where the effect should be placed. Anti-missiles do not create
// projectiles; they just create a blast animation.
start += (.5 * range) * offset.Unit();
Angle aim = TO_DEG * atan2(offset.X(), -offset.Y());
for(const auto &eit : outfit->HitEffects())
for(int i = 0; i < eit.second; ++i)
{
effects.push_back(*eit.first);
effects.back().Place(start, ship.Velocity(), aim);
}
Fire(ship);
return (Random::Int(strength) > Random::Int(projectile.MissileStrength()));
}示例2: Point
double AsteroidField::Asteroid::Collide(const Projectile &projectile, int step) const
{
Point pos = location - projectile.Position();
pos = Point(-remainder(pos.X(), WRAP), -remainder(pos.Y(), WRAP));
return animation.GetMask(step).Collide(pos, projectile.Velocity(), angle);
}示例3: TakeDamage
// This ship just got hit by the given projectile. Take damage according to
// what sort of weapon the projectile it.
int Ship::TakeDamage(const Projectile &projectile, bool isBlast)
{
int type = 0;
const Outfit &weapon = projectile.GetWeapon();
double shieldDamage = weapon.ShieldDamage();
double hullDamage = weapon.HullDamage();
double hitForce = weapon.HitForce();
double heatDamage = weapon.HeatDamage();
double ionDamage = weapon.IonDamage();
bool wasDisabled = IsDisabled();
bool wasDestroyed = IsDestroyed();
if(shields > shieldDamage)
{
shields -= shieldDamage;
heat += .5 * heatDamage;
ionization += .5 * ionDamage;
}
else if(!shields || shieldDamage)
{
if(shieldDamage)
{
hullDamage *= (1. - (shields / shieldDamage));
shields = 0.;
}
hull -= hullDamage;
heat += heatDamage;
ionization += ionDamage;
}
if(hitForce && !IsHyperspacing())
{
Point d = position - projectile.Position();
double distance = d.Length();
if(distance)
ApplyForce((hitForce / distance) * d);
}
if(!wasDisabled && IsDisabled())
type |= ShipEvent::DISABLE;
if(!wasDestroyed && IsDestroyed())
type |= ShipEvent::DESTROY;
// If this ship was hit directly and did not consider itself an enemy of the
// ship that hit it, it is now "provoked" against that government.
if(!isBlast && projectile.GetGovernment() && !projectile.GetGovernment()->IsEnemy(government)
&& (Shields() < .9 || Hull() < .9 || !personality.IsForbearing())
