NWScript:

SetLocalInt(OBJECT_SELF, "iDoTether", 1);

to the creatures' OnSpawn script

Anyway, here's the script:

NWScript:

//*******************************************************\\
//  Random walk with tether to limit distance travelled  \\
//                                                       \\
//  Created by Perturbatio 16th July 2002                \\

//  Remember to uncomment the line                       \\
//  SetSpawnInCondition(NW_FLAG_HEARTBEAT_EVENT);        \\
//  in the OnSpawn script of the creature you want to    \\
//  affect.                                              \\
//*******************************************************\\
void main()
{
    //get the event number
    int nUserEvent = GetUserDefinedEventNumber();
    // get the object of the calling creature
    object oSelf = OBJECT_SELF;
    if(nUserEvent == 1001) //HEARTBEAT EVENT
    {
        // the following will move the creature a random distance
        // away from the location lTether
        // lTether should be a location with the tag set to TETHER_<CREATURETAG>
        // where <CREATURETAG> is the tag of the creature you want this script to affect
        // i.e. TETHER_NW_GUARD01
        // if there is no tether then it will use the starting location of the creature
        // must set the a local int on the creature object named iDoTether with a value of 1
        // used so that you can prevent them doing a random walk if need be
        // if you want the creature to do it from the start, put
        // SetLocalInt(OBJECT_SELF, "iDoTether", 1);
        // in the creatures OnSpawn event (copy the script first).
        if (GetLocalInt(oSelf,"iDoTether")){
            int iMaxDistance = 9;
            location lTether;
            string sTether = "TETHER_" + GetTag(oSelf);
            object oTetherWaypoint = GetWaypointByTag( sTether );
            if (!(GetLocalInt(oSelf, "iHasTether"))){
                if (GetIsObjectValid( oTetherWaypoint ))
                {
                    lTether = GetLocation( oTetherWaypoint );
                } else {
                    lTether = GetLocation( oSelf );
                }
                // Set the tether location on the creature object
                SetLocalLocation(oSelf, "lTether", lTether);
                // The object now has a tether
                SetLocalInt(oSelf, "iHasTether", 1);
            }
            lTether = GetLocalLocation(oSelf, "lTether");
            vector vLocationVector = GetPositionFromLocation(lTether);
            vLocationVector.x += (Random(iMaxDistance) - Random(iMaxDistance)) ;
            vLocationVector.y += (Random(iMaxDistance) - Random(iMaxDistance)) ;
            location lWalkTo = Location(GetArea(oSelf), vLocationVector, Random(361) * 1.0);
            SetLocalLocation(oSelf, "WalkTo", lWalkTo);
            ActionMoveToLocation(lWalkTo);
        }
    }
    return;
}

Place it in the userdefined event to use it.
