Please elaborate. How many of this type actor can be in the world at one time? Is there always at least one in the world? What is the class name that the actor is created from? What have you tried in your world in an attempt to access the actor and execute its method?

I need to be able to access a certain method from a "Person" actor which only ever has one instance in the world at any one time. I was wondering how to find the actor's equivalent to GetWorld(parameter).BasicExample(parameter), but still haven't caught on whether it's even a thing. Thanks in advance.

Person person = (Person) getObjects(Person.class).get(0);
person.<< method name >>();

or

((Person) getObjects(Person.class).get(0)).<< method name >>();

To avoid the complications, you could just keep a reference to the person in your world:

public class MyWorld extends World
{
    Person person = new Person();
    
    public MyWorld()
    {
        super(600, 400, 1);
        addObject(person, getWidth()/2, getHeight()/2);
        ...
    }
    
    ...
    
    public void whatever()
    {
        ...
        person.<< method name >>();
    ...
