Artificial Intelligence in Video Games: Towards a Unified Framework

Algorithm 4

Tanking capacity estimation. This function could be used to evaluate how fit of a tank a unit or character is.

double  score_tanking(Unit  u, UnitList & grp, UnitList & enemies)

{

 //Set the base score to the current unit hit points

 double  score = u->hitpts();

 //Get primary damage type of enemy

 DamageType dt = get_primary_dtype(enemies);

 //Get current damage reduction of the unit

 double  dr = u->dmgred(dt);

 //Factor in average reduction bonus from ally abilities

 dr += dmgred_abilities(u, grp, dt);

 //Factor in average amplification bonus from enemy abilities

 dr −= dmgamp_abilities(u, enemies, dt);

 if  (dr >= 1.0)

  return  numeric_limits<double >::infinity();

 //Estimate effective hit points

 score  = 1.0/(1.0 − dr);

 return  score;
