Don't wolves attack *all* players when they are aggravated? So just flipping their "IsAngry" flag should be enough.

I expect a code like this should work (written from the top of my head, may not compile):

function cWolf::DoTakeDamage(TakeDamageInfo & a_TDI)
{
  super:DoTakeDamage(a_TDI);
  if (m_IsTame)
  {
    // No aggravating for tame wolves
    return;
  }
  if (a_TDI.DamageType != dtAttack)
  {
    // Not attacked by a player, bail out
    // TODO: projectiles use dtRangedAttack with a projectile entity in the Attacker field, handle that too
    return;
  }

  ASSERT(a_TDI.Attacker != NULL);
  class cCallback : public cEntityCallback
  {
  public:
    Vector3f m_AttackerPos;

    cCallback(const Vector3f & a_AttackerPos) : m_AttackerPos(a_AttackerPos) {}

    virtual bool OnEntity(cEntity & a_Entity) override
    {
      // AGGRAVATE_RANGE is the range in blocks in which the wolves become angry; define that constant at the top of Wolf.cpp as static const double
      if (a_Entity.IsMob() && (((cMonster &)a_Entity).GetMobType() == mtWolf) && ((a_Entity.GetPos() - m_AttackerPos).SqrLength() < AGGRAVATE_RANGE * AGGRAVATE_RANGE))
      {
        ((cWolf &)a_Entity).SetAngry(true);
      }
      return false;
    }
  } Callback(a_TDI.Attacker.GetPos());
  m_World->ForEachEntity(Callback);
}
