How can I move an Actor to another Actor?

hi, I have a problem, I want an actor to detect when there is a certain other actor in the world and then automatically move to it. Is that possible somehow?

You can get a list of all actors of any type with: 
java.util.List actors = getWorld().getObjects(Actor.class);
Replace Actor with any Actor subclass name for a specific type of actor. If the list, actors, is not empty, you can get a reference to the actor listed (presuming no more than one is ever in the world). With that reference, you can get the coordinates to turn toward (or move toward): 
if (! actors.isEmpty())
{
    Actor actor = (Actor)actors.get(0);
    turnTowards(actor.getX(), actor.getY());
    move(3);
    // setRotation(0); // to maintain upright actor
}
