Artificial Intelligence in Video Games: Towards a Unified Framework

Algorithm 8

Modifications in the conceptual copy of a Raven class. No game behavior is defined in CDS, which hosts nothing more than a projection of the game state.

class  Raven_Weapon

{

 //this discharges a projectile from the weapon at the given target position (provided

   the weapon is ready to be discharged… every weapon has its own rate of fire)

 virtual void  ShootAt(Vector2D pos) = 0;

 void  IncrementRounds(int  num)

 {

  m_iNumRoundsLeft  +=  num;

  Clamp(m_iNumRoundsLeft, 0, m_iMaxRoundsCarried);

  //Synchronize rounds in CDS

  GetCptWeapon()->SetNumRoundsLeft(m_iNumRoundsLeft);

 }

 ⋯

};

class  CptWeapon

{

 ⋯

 //Removed

 //virtual void ShootAt(Vector2D pos) = 0;

 void  SetNumRoundsLeft(int  n)

 {

  m_iNumRoundsLeft = n;

 }

 ⋯

};
