I want the code to look somethings like this but this didnt work either 
    
    private void GetNextWaypoint()
        {
        if(wavepointIndex >= Waypoints.points.Length - 1)
            {
            EndPath();
            return;
            }
            
    
    private void GetNextWaypoint()
        {
        if(wavepointIndex >= Waypoints.points.Length - 1)
            {
            EndPath();
            return;

causes problems in the waypoint scripts I think i have to start over on the scripts... I'm just trying to get the enemy to follow waypoints and point in the correct direct at each turn
