Change background on collision

I am trying to get it so that when the player object runs into a portal the background image the level switches. All objects are gone and a new screen appears. I need the player to be able to go through a first portal to get to the "equipment screen" and then go through a second portal to get back to the game. The second portal essentially starts the next level. At the moment, I can get the first portal to work the very first time I load up the scenario and then after that when you run the scenario the background image switches immediately without running into the portal at all. This is the code for the first Portal.

        Sworde a = (Sworde) getOneIntersectingObject(Sworde.class);

        {
            newLevel = true;
             
        }
        else
        {
            newLevel = false;
        }
    }
This is currently the world code.

Any help is greatly appreciated. I am really not sure why this is is not working.

Fields that are declared 'static' are not re-initialized when the project is reset -- only when the project is compiled. You need to initialize it in your initial world constructor. Place the following at line 25 in your MyWorld class:
?

Portal.newLevel = false;

Okay, I have done this and the problem still persists. Again, when I remove the methods that are supposed to be operated by a boolean switch this issue doesn't occur but the values shouldn't allow a switching of the background to happen.

Sorry I meant when I check the values they say they are false and if that is true the if block shouldnt happen at all.

I am so confused by this because it was working and I am saying that these values should be false all over the place but it still changes.

Apparently you have 'static' fields in other classes that will need to be initialized in the MyWorld class as well (to mention one, PortaltoPlanet.nextLevel).
