Inside one of my classes ElevatorDoors there is a interger Elevatorframe public int Elevatorframe = 1; Inside of my world class MainMenu I am trying to change Elevatorframe back to 1 so the doors open again when a certain class dies. I tried int ElevatorFrame = ((ElevatorDoors)(getObjects(ElevatorDoors.class).get(0))).ElevatorFrame(); but could not get it to work public void removeLives() { lives--; showLives(); Akari akari = new Akari(); addObject(akari,67,200); if(lives == 0 ) { Greenfoot.setWorld(new GameOver()); } }

What code do you have for the ElevatorFrame() method in your ElevatorDoors class?

I do not see an ElevatorFrame method in this class. Would it be in your Interactables class or is it that there is no method called ElevatorFrames -- only a field?

Yeah right sorry, only a field

Then, you were sort of close with your initial line; only, I do not see how that could possibly be an attempt to set its value back to 1. Try:

((ElevatorDoors)getObjects(ElevatorDoors.class).get(0)).Elevatorframe = 1;

Your ElevatorDoors class can be simplified to:

import greenfoot.*;

public class ElevatorDoors extends Interactables
{
    private GreenfootImage[] elevators = new GreenfootImage[18];
    private int frame = 1;
    
    public ElevatorDoors()
    {
        for (int i=0; i<18; i++) elevators[i] = new GreenfootImage("ELEVATOR"+(i+1)+".png");
    }
    
    public void act()
    {
        open();
    }
    
    private void open()
    {
        if (frame < 28)
        {
            frame++;
            if (frame > 10) setImage(elevators[frame-10];
        }
    }
}

You never cease to amaze me danpost, thanks for the help I really do appreciate it. And the simplification was something that someone else just suggested to me while i was streaming coding so that really helps a lot man!

import greenfoot.*;
 
public class ElevatorDoors extends Interactables
{
    public int Elevatorframe = 1;
    private GreenfootImage[] allFrames = new GreenfootImage[18];
    public ElevatorDoors()
    {
        for (int i=0; i<18; i++) allFrames[i] = new GreenfootImage("ELEVATOR"+(i+1)+".png");
    }
     
    public void act()
    {
        Elevatorframe++;
        if(Elevatorframe<allFrames.length){
            setImage(allFrames[Elevatorframe]);
        }
    }
}

Did a little bit of adjustment and such
