How do I get the Player or AIPlayer Speed in C++?

void Player::pickActionAnimation()
{
   // Only select animations in our normal move state.
   if (mState != MoveState || mDamageState != Enabled)
      return;

   if (isMounted()) 
   {
      // Go into root position unless something was set explicitly
      // from a script.
      if (mActionAnimation.action != PlayerData::RootAnim &&
          mActionAnimation.action < PlayerData::NumTableActionAnims)
         setActionThread(PlayerData::RootAnim,true,false,false);
      return;
   }
   
   bool forward = true;
   U32 action = PlayerData::RootAnim;
   if (mFalling) 
   {
      // Not in contact with any surface and falling
      action = PlayerData::FallAnim;
   }
   else
   {
      if (mContactTimer >= sContactTickTime) {
         // Nothing under our feet
         action = PlayerData::RootAnim;
      }
      else 
      {
         // Our feet are on something
         // Pick animation that is the best fit for our current velocity.
         // Assumes that root is the first animation in the list.
         F32 curMax = 0.1;
         VectorF vel;
         mWorldToObj.mulV(mVelocity,&vel);
         for (U32 i = 1; i < PlayerData::NumMoveActionAnims; i++) 
		 {
            PlayerData::ActionAnimation &anim = mDataBlock->actionList[i];
            if (anim.sequence != -1 && anim.speed) {
               F32 d = mDot(vel, anim.dir);
               if (d > curMax) 
               {
                  curMax = d;
                  action = i;
                  forward = true;
               }
               else
               {
                  // Special case, re-use slide left animation to slide right
				   if (i == PlayerData::SideLeftAnim && -d > curMax) 
                  {
                     curMax = -d;
                     action = i;
                     forward = false;
                  }
			   }
			}
		 }
	  }
   }
   
   //AIPlayer::getMoveSpeed
   //Player::getVelocity;
   //VectorF vel;
   //mWorldToObj.mulV(mVelocity,&vel);
   //F32 d = mDot(vel, anim.dir);
   //if (d < 0.5 &&  d > 0.1)
   //   action = PlayerData::WalkForwardAnim;
   
   setActionThread(action,forward,false,false);
}

I need to be able to get the getMoveSpeed of the AIPlayer that is using this animation. I am going to use it to make the AIPlayer walk if there setMoveSpeed is less than 0.5 and run if there speed is above 0.5. I can't figure out how to get the speed of the Player or AIPlayer that is using this pickActionAnimation. Thanks in advance for any help anyone can provide.
