Follow + Random Walk

  OnHeartbeat can be possible, but I would use some other. For example OnPerception and use a pseudo heartbeat....
  You should check the position of the PC, with a saved position from him. If it has changed, clear all actions and follow/move to the new position, or if not walk randomly. At last, redo this check and action.
  Yet, I'm not at the toolset, so I have no script handy...

  That sounds pretty interesting, the OnPerception idea. I'll do some experimenting. Thanks for that!

  Thought I'd share what I came up with... I ended up using only a heartbeat script but it worked beautifully! It could probably be tweaked and improved though.
  
  The creature in question is a Lantern Archon that will follow the PC around to provide light. My next step is creating my own RandomWalk function to have more control, as I'm willing to incorporate this system to the henchman in my module.
  
  

  const int FOLLOW = 0;
  const int WANDER = 1;
  
  void SetFollowMode(int iMode, object oPC)
  {
      SetLocalInt(OBJECT_SELF, "FollowMode", iMode);
  
      ClearAllActions();
      switch (iMode)
      {
          case FOLLOW:
          ActionForceFollowObject(oPC, 2.0f);
          break;
  
          case WANDER:
          ActionRandomWalk();
          break;
      }
  }
  
  int GetFollowMode()
  {
      int iMode = GetLocalInt(OBJECT_SELF, "FollowMode");
  
      return iMode;
  }
  
  void main()
  {
      object oPC = GetFirstPC();
  
      /// Get current PC position.
      vector vPC1 = GetPosition(oPC);
  
      /// Get stored PC position.
      float vPCx = GetLocalFloat(OBJECT_SELF, "vPC.x");
      float vPCy = GetLocalFloat(OBJECT_SELF, "vPC.y");
      float vPCz = GetLocalFloat(OBJECT_SELF, "vPC.z");
      vector vPC2 = Vector(vPCx, vPCy, vPCz);
  
      /// Are they the same?
      if (vPC1 == vPC2)
      {
          if (GetFollowMode() != WANDER)
          {
              SetFollowMode(WANDER, oPC);
          }
      }
      else
      {
          if (GetDistanceBetween(OBJECT_SELF, oPC) > 5.0)
          {
              if (GetFollowMode() != FOLLOW)
              {
                  SetFollowMode(FOLLOW, oPC);
              }
          }
      }
  
      /// Store new position.
      SetLocalFloat(OBJECT_SELF, "vPC.x", vPC1.x);
      SetLocalFloat(OBJECT_SELF, "vPC.y", vPC1.y);
      SetLocalFloat(OBJECT_SELF, "vPC.z", vPC1.z);
  }
