Artificial Intelligence in Video Games: Towards a Unified Framework

Algorithm 20

Synchronizing conceptual unit state. Some attributes are not required by the targeting AI and only serve as illustrations.

void  GravenAIModule::syncUnit(CptMvAgent2D  u, Unit unit)

{

 //Synchronize CptEntity2D attributes

 u->SetID(unit->getID());

 u->SetEntityType(cpttype_bot);

 u->SetScale(1);

 u->SetBRadius(MAX(unit->getType().height()  /  2, unit->getType().width()  /  2));

 u->SetPos(Vector2D(unit->getPosition().x, unit->getPosition().y));

 //Synchronize CptMvEntity2D attributes

 u->SetHeading(Vector2D(unit->getVelocityX(), unit->getVelocityY()));

 u->SetVelocity(Vector2D(unit->getVelocityX(), unit->getVelocityY()));

 u->SetMass(1);

 u->SetMaxSpeed(unit->getType().topSpeed());

 u->SetMaxTurnRate(unit->getType().turnRadius());

 u->SetMaxForce(unit->getType().acceleration());

 //Synchronize CptMvAgent2D attributes

 u->SetMaxHealth(unit->getType().maxHitPoints() + unit->getType().maxShields());

 u->SetHealth(unit->getHitPoints() + unit->getShields());

 u->SetScore(unit->getKillCount());

 u->SetPossessed(false );

 u->SetFieldOfView(360);

 u->Face(Vector2D(unit->getVelocityX(), unit->getVelocityY()));

 u->SetWorld(this ->cptWorld);

 u->SetStatus(unit->exists() ? CptMvAgent2D::alive: CptMvAgent2D::dead);

 u->SetPlayer(unit->getPlayer()->getID());

 u->SetSightRange(unit->getType().sightRange());

 u->SetPlane(unit->isFlying());

 u->SetAirReach(unit->getType().airWeapon() != WeaponTypes::None);

 u->SetGroundReach(unit->getType().groundWeapon() != WeaponTypes::None);
