Level model not load in BaseAppState help please

Where do you attach it?

Also:

Dont konow.
I need two classes for:1) movind in world 2) battle
how to do this with BaseAppState
how to attach BaseAppState?

4

Where did you learn about BaseAppState?

Have you done the tutorials?

Did you try a simpler example first?

5

I learn Application States :: jMonkeyEngine Docs

this is a simple example

  1. create state
  2. load model
6

Read carefully:

Look at step 3.

7

try this

       
       Level level = new Level();
       stateManager.attach(level);
       level.setEnabled(true);
}

    @Override
    protected void initialize(Application app) {
        app = (SimpleApplication)app;


        super.initialize(app.getStateManager(),app);
}```

error

What told you to do that? Don’t do that. It’s an endless loop because super.initialize will call initialize which now calls super.initialize(), and so on.

Get a simple working example without any extra stuff.

Add log messages to see what’s happening or step through in the debugger.

I think it’s the only way you will learn what’s happening.

Simplest example possible:

public class SimpleState extends BaseAppState {

    public SimpleState() {        
    }
    
    @Override
    protected void initialize( Application app ) {
        System.out.println("I'm being initialized:" + this);
    }
    
    @Override
    protected void cleanup( Application app ) {
        System.out.println("I'm being cleaned up:" + this);
    }
    
    @Override
    protected void onEnable() {
        System.out.println("I'm being enabled:" + this);
    }
    
    @Override
    protected void onDisable() {
        System.out.println("I'm being disabled:" + this);
    }
}

Then in simple init:

    stateManager.attach(new SimpleState());
