[SOLVED][Slick2D][States] Problem with entering state.

Newbie & Debugging Questions
#1

Hello, sorry for bad english.
I am working at small java game in slick2D. I have a problem with states. I’m adding them in main class like this:


    public static final int map = 10;
    public static final int recBack = 0;
    public static final int recDiv = 1;
    public static final int Prim = 2;

@Override
    public void initStatesList(GameContainer gc) throws SlickException {
        this.addState(new Level(recBack, new RecursiveBacktracking()));
        this.addState(new Level(recDiv, new RecursiveDivision()));
        this.addState(new Level(Prim, new PrimsAlg()));
        this.addState(new Map(map));
        this.enterState(recBack);  ///<<<<-------------------------------------
        
//        this.getState(recBack).init(gc, this);
//        this.getState(recDiv).init(gc, this);
//        this.getState(Prim).init(gc, this);
//        this.getState(map).init(gc, this);
//        
//        this.enterState(recBack);  
    }

Whatever state I try to enter, it always starts with one with biggest stateID (excluding Map, which doesn’t have anything in init()).

Later in code of state, I try to enter other state if conditions are met, it just restarts the same level, but stateID changes:


            if ((hero.getBlockX() == GridX - 1) && (hero.getBlockY() == GridY - 1) && (grid.getLockState())) {
                    if (state == (Main.getInstance().getStateCount() - 2)) {
                        nextstate = 0;
                    } else {
                        nextstate = state + 1;
                    }
                    //Main.getInstance().getState(state).leave(gc, sbg);
                    //Main.getInstance().getState(nextstate).init(gc, Main.getInstance());
                    //Main.getInstance().getState(nextstate).enter(gc, Main.getInstance());

                    Main.getInstance().enterState(nextstate);  //<<<----------------------------------
                    initialized = false;
            }

I’m quite stressed because this is part of my bachelor work, I really apreciate any help.
