//      Random walk script

//      (c) weecc 2002

//***********************************

//This script goes into the area's OnHeartbeat event

//You need to create a bunch of NPCs, all bearing the same "NPC1" tag

//as well as a number of waypoints whose tags are in the format

//of "way_1", "way_2", etc. Make sure that the number of waypoints that you

//use corresponds with the number in the random function under the

//wander() subroutine. You can keep adding NPCs to this script as long as they

//all have the same "NPC1" tag. I tried this with about 20 NPCs, and they

//seemed to behave properly.

//All comments -> weecc@roots.com.my

void wander (int count)

{

    //This script randomly chooses one out of eight waypoints and assigns

    //it as a destination for a NPC to walk to

    int s;

    for (s=0; s<=count; ++s)

        {

        object oNPCw                    = GetObjectByTag("NPC1", s);

        //Change the number inside the random function to reflect the number

        //of waypoints that you are using. For example, if I had only five

        //waypoints, it would read Random (5)

        int i                           = Random(8);

        string si                       = IntToString(i);
