Show detectHuman method.

this is the detectHuman method 
public void detectHuman()
    {
        int dist = 100;
        Actor closest = null;

        if(!getObjectsInRange(dist, Betty.class).isEmpty())
        {
            for (Object obj: getObjectsInRange(dist, Betty.class))
            {
                Actor guy = (Actor) obj;
                int guyDist = (int) Math.hypot(guy.getX() - getX(), guy.getY() - getY());
                if (closest == null || guyDist< dist)
                {
                    closest = guy;
                    dist = guyDist;
                }
            }
            turnTowards(closest.getX(),closest.getY());
        }   
    }

Your fire method treats the detectHuman method as if it returns a boolean value, when in fact, it does not. Side note: closest in detectHuman could still be null by line 18.

You could invoke fire from the detectHuman method (instead of from act).

Remove lines 17 thru 20. Replace lines 28, 48 and 68 with: 
if (closest != null)
{
    turnTowards ...
    shoot();
}
