GetWaypoint() returns the transform of the waypoint at the index passed in via the
integer index.
public Transform GetWaypoint(int index)
{
if( shouldReverse )
{
This is the only place in the class where shouldReverse is used. GetWaypoint will
reverse the index numbers of the waypoints when shouldReverse is true (i.e., using
GetWaypoint to get a waypoint with the index number of zero would return the last way-
point in the path, instead of the first).
To reverse the index passed in to this function, the variable index is modified by sub-
tracting it from the number of transforms in totalTransforms.
// send back the reverse index'd waypoint
index=(totalTransforms)-index;
if(index<0)
index=0;
}
