Artificial Intelligence in Video Games: Towards a Unified Framework

Algorithm 22

The update function of the CptBot class. The function uses the Attack conceptual control to issue commands to the units in the game.

void  CptBot::Update()

{

 //if the bot is under AI control but not scripted

 if  (!GetAgent()->isPossessed())

 {

  //examine all the opponents in the bots sensory memory and select one

  //to be the current target

  if  (m_pTargetSelectionRegulator->isReady())

  {

   m_pTargSys->Update();

  }

  //update the sensory memory with any visual stimulus

  if  (m_pVisionUpdateRegulator->isReady())

  {

   m_pSensoryMem->UpdateVision();

  }

  //Attack

  if  (m_pAttackRegulator->isReady() && m_pTargSys->isTargetPresent())

  {

   Attack(m_pOwner->ID(), m_pTargSys->GetTarget()->ID());

  }

 }
