Artificial Intelligence in Video Games: Towards a Unified Framework

Algorithm 3

Primary tank designation. This function could be used to determine which unit or character should engage the enemy.

void set_tank(UnitList & grp)
{
//Get a list of the enemies the group is fighting
UnitList enemies = get_nearby_threats(grp);
Unit toughest = NULL;
double score = 0;
//For each unit in the group, estimate its toughness against the enemy
UnitList::iterator u;
for (u = grp.begin(); u != grp.end(); ++u)
{
double cs = score_tanking(u, grp, enemies);
if (cs > score)
{
toughest = u;
score = cs;
}
}
//Assign the role of tank to the toughest unit in the group
if (score > 0)
set_role(toughest, Role::tank);
}
