I am working on a game using LibGdx and Java. While I play the game, sometimes I get this run-time error that I never saw before and I have no idea what it means.

EDIT: I was able to find out that the application crashes (only sometimes) in the function below:

@Override
    public void defineItem() {
        System.out.println("mushroom going to be created");
        BodyDef bdef = new BodyDef();
        System.out.println("1");
        bdef.position.set(getX(), getY());
        System.out.println("2");
        bdef.type = BodyDef.BodyType.DynamicBody; 
        System.out.println("3");
        _body = _world.createBody(bdef); //The application crashes here...
        System.out.println("4");
        FixtureDef fdef = new FixtureDef();
        CircleShape circle = new CircleShape();
        circle.setRadius(6 / MarioBros.PPM);

        fdef.filter.categoryBits = MarioBros.ENEMY_BIT;
        fdef.filter.maskBits = MarioBros.GROUND_BIT |
                MarioBros.COIN_BIT |
                MarioBros.BRICK_BIT |
                MarioBros.ENEMY_BIT |
                MarioBros.OBJECT_BIT |
                MarioBros.MARIO_BIT;

        fdef.shape = circle;
        _body.createFixture(fdef).setUserData(this);
        System.out.println("mushroom added");
    }

Can someone give me some help? Please let me know if I need to show any more details or code from my application.

Thank you and merry Christmas!

  • I also would like to say that it looks some kind of segmentation fault, but I don´t even know how it is possible in java. Commented Dec 25, 2016 at 2:06

After some debugging and some talking with other friend we found out the problem was that I was removing a Body from the World (both Box2D classes) and after that I was calling a method on that body (the method was setActive(true)).

The solution was to set the Body to null after he destruction, this allowed me to get a NullPointerException when if I tried to use that body after his destruction and finally find the bug on the application.

In conclusion: If you use Box2D always set a Body to null after it gets destroyed in the World.

I'm getting the same error using almost identical code. I've tried setting the body to null but I'm not getting an exception. Have you got any more info on this? I'm really struggling.
In my case I just set the body to null IN EVERY SINGLE ENTITY of my game and It worked. Maybe the problem in your application is other?
FOUND IT !!!! You were right, the issue seemed to be with one of the other entities, not the one I thought most likely or the one most recently added. Thank you. Hours of frustration - resolved.
