Variables not taking on the proper boolean (true or false)

#
I am trying to create a game that when two pictures are connected and correctly corresponding a new screen or object appears. It seems as though my objects are not taking on the variables that they should be. This is what happens when the 2 objects collide. I know that part of it is working because the new Greenfoot Image "IntAnswer3" is drawn. The problem is that the object Int3 is not taking on the connected or correct variables that I need it to. How do I fix this? 
 private void collision1(){
        LogarithmInteractive interactive = (LogarithmInteractive)getWorld();
        if (removed == false){
            if (!interactive.getObjects(IntPlaceholder2.class).isEmpty()) {
                Actor int2Img = getOneIntersectingObject(IntPlaceholder2.class);
                if (int2Img != null){
                    getWorld().removeObject(int2Img);
                    GreenfootImage image = new GreenfootImage("IntAnswer3.png");
                    getWorld().getBackground().drawImage(image,490,35);
                    getWorld().removeObject(this);
                    connected = true; 
                    correct = false;
                    removed = true;
                }     
            }   
        }        
    }

These variables are set to the correct values, but well, you remove the object, so it is gone.

#
I am no longer removing the object, but the world still is not getting the correct boolean values. Any other suggestions?

Where do you try to give the values to the world?

Here is the world class. The boolean variable values should transfer to this and then enact this code.

        }
    }
    
    /**

     * Once all have been done, a message is displayed.

            GreenfootImage image = new GreenfootImage("cactus.png");
            getBackground().drawImage(image,150, 360);
          
            if (reset == true){
                Greenfoot.setWorld(new LogarithmInteractive());

Please show the entire Int3 class code. I have a feeling that the problem may be elsewhere in the class.

I do not see anything amiss in that class. The most likely place now would be in your LogarithmInteractive class. Let us see that one. The most probable cause in that class would be that you used 'new Int3()' more than once in the class. If that is the case, then you probably did the same with the other int#s as well.

Lines 14 through 16 create the required objects. You need not create more on lines 59, 61 and 63 (removes these lines). Same thing with lines 43, 45 and 47 (remove them).
