A lot of people are dazzled about waypoints. Waypoints are nothing more than a reference point in a path or route.
Attached is an example I just coded tonight to show how waypoints are created. If you wanted to do something where an object follows the waypoints you simply create a loop that will point the object at the next waypoint and tell it to move foward.
Hope that helps you out!

DarkScript Source:
// Create waypoint array that will store the x, y, and z locations
global waypoint = array(0);
// These variables will be used as temporary
// variables to hold the x, y, z locations
// that get inserted into the waypoint array
global newX;
global newY;
global newZ;
global AddWaypoint = function()
{
// Obtain the array size
szArray = waypoint.Size();
// Adding 1 to the array size
// so that we can resize it for
// the new waypoint
szArray = szArray + 1;
waypoint.Resize(szArray);
// Position the size back to our original position
szArray = szArray - 1;
// Insert the table into the array
waypoint[szArray] = table(X = 0, Y = 0, Z = 0);
// Putting our x, y, z location into the array
waypoint[szArray].X = newX;
waypoint[szArray].Y = newY;
waypoint[szArray].Z = newZ;
};
global PrintWaypoint = function()
{
// Grab the total number of waypoints stored
szArray = waypoint.Size();
szArray = szArray - 1;
// Check to see if no waypoints are being stored
if (szArray == -1)
{
return;
}
// Print details about the last waypoint clicked
PrintString("Waypoint Number: " + (szArray+1).String());
PrintString("X: " + waypoint[szArray].X.String());
PrintString("Y: " + waypoint[szArray].Y.String());
PrintString("Z: " + waypoint[szArray].Z.String());
};
