Libgdxのシーンを変更しても前のシーンは破棄されない

シーンAIにはボタンが少なく、そのうちの1つがシーンBになります。シーンBを開くと、テーブル要素が正しく配置されず、前のシーンのボタンは見えません前のシーンからそのボタンの位置をタップすると、シーンAで開くシーンが開きます。Libgdxのシーンを変更しても前のシーンは破棄されない

これはあなたにとって意味があると思います。

私は問題が処理方法にあると考えています。

は、ここに私のシーンBのコードです：

public class Postavke implements Screen { 

    Main main = null; 

    // KONSTRUKTOR ZA MJENJANJE SCENE 
    public Postavke(Main gm){ 
     main = gm; 
    } 

    Stage postavkeStage = null; 
    private Image pozadina = null; 


    @Override 
    public void show() { 
     postavkeStage = new Stage(new StretchViewport(1920, 1080)); 
     pozadina = new Image(new Texture(Gdx.files.internal("pozadinaPostavke.png"))); 
     postavkeStage.addActor(pozadina); 
     postavkeButtoni(); 
    } 

    @Override 
    public void render(float delta) { 
     Gdx.gl.glClearColor(0, 0, 0, 0); 
     Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); 
     postavkeStage.draw(); 
     postavkeStage.act(); 
    } 

    @Override 
    public void resize(int width, int height) { 

    } 

    @Override 
    public void pause() { 

    } 

    @Override 
    public void resume() { 

    } 

    @Override 
    public void hide() { 

    } 

    @Override 
    public void dispose() { 
     postavkeStage.dispose(); 

    } 

    private void postavkeButtoni(){ 
     Table postavkeButtoni = new Table(); 
     postavkeButtoni.setFillParent(true); 

     final Image zvukButton = new Image(new Texture(Gdx.files.internal("postavkemutebutton.png"))); 
     final Image homeButton = new Image(new Texture(Gdx.files.internal("homebutton.png"))); 
     final Image mailButton = new Image(new Texture(Gdx.files.internal("postavkegmailbutton.png")));

     final Image zaslugeButton = new Image(new Texture(Gdx.files.internal("postavkezaslugebutton.png"))); 



     zvukButton.addListener(new InputListener() { 
      public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){ 
       zvukButton.addAction(Actions.scaleTo(1, 1.1f,.1f)); 
       return true; 
      } 

      public void touchUp (InputEvent event, float x, float y, int pointer, int button){ 
       zvukButton.addAction(Actions.scaleTo(1, 1,.1f)); 
       main.setScreen(new MainMenu(main)); 
      } 
     }); 

     homeButton.addListener(new InputListener() { 
      public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){ 
       homeButton.addAction(Actions.scaleTo(1, 1.1f,.1f)); 
       return true; 
      } 

      public void touchUp (InputEvent event, float x, float y, int pointer, int button){ 
       homeButton.addAction(Actions.scaleTo(1, 1,.1f)); 
      } 
     }); 

     mailButton.addListener(new InputListener() { 
      public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){ 
       mailButton.addAction(Actions.scaleTo(1, 1.1f,.1f)); 
       return true; 
      } 

      public void touchUp (InputEvent event, float x, float y, int pointer, int button){ 
       mailButton.addAction(Actions.scaleTo(1, 1,.1f)); 
      } 
     }); 

     instagramButton.addListener(new InputListener() { 
      public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){ 
       instagramButton.addAction(Actions.scaleTo(1, 1.1f,.1f)); 
       return true; 
      } 

      public void touchUp (InputEvent event, float x, float y, int pointer, int button){ 
       instagramButton.addAction(Actions.scaleTo(1, 1,.1f)); 
      } 
     }); 

     zaslugeButton.addListener(new InputListener() { 
      public boolean touchDown (InputEvent event, float x, float y, int pointer, int button){ 
       zaslugeButton.addAction(Actions.scaleTo(1, 1.1f,.1f)); 
       return true; 
      } 

      public void touchUp (InputEvent event, float x, float y, int pointer, int button){ 
       zaslugeButton.addAction(Actions.scaleTo(1, 1,.1f)); 
      } 
     }); 

     postavkeButtoni.add(homeButton).expand().top().left().pad(20); 
     // postavkeButtoni.row(); 
     postavkeButtoni.add(zvukButton); 
     //postavkeButtoni.row(); 
     HorizontalGroup drustveneMrezeIZasluge = new HorizontalGroup(); 
     postavkeButtoni.addActor(mailButton); 
     postavkeButtoni.addActor(instagramButton); 
     postavkeButtoni.addActor(zaslugeButton); 

     postavkeStage.addActor(postavkeButtoni); 

    } 
}

は、なぜそれが適切なものを配置し、シーンAを破壊されていませんか？

あなたは私 'SceneA'を提供することができますか？ – Crowni

これは最初の投稿にあります – DaxHR

mainMenu = new Stage（new StretchViewport（1920、1080））;コンストラクタに。 – Hllink

シンプルコード：

1- MainGameの作成はGameを拡張：

public class Main extends Game { 

    @Override 
    public void create() { 
     setScreen(new SceneA()); 
    } 
    @Override 
    public void dispose() { 
    // your SceneA and SceneB here will dispose here after you call setScreen(new ____()); 
     getScreen().dispose(); 
     System.out.println("\n" + getScreen().getClass().getSimpleName() + " disopsed"); 
     System.out.println("========================================================="); 
    } 
}

2 - Craete SceneAはScreenを実装します。

public class SceneA implements Screen { 

    private Stage stage; 

    @Override 
    public void show() { 
     System.out.println("\nshow SceneA"); 

     stage = new Stage(new StretchViewport(1920, 1080)); 

     Image button = new Image(new Texture("____.png")); 
     button.addListener(new ClickListener() { 
      public void clicked(InputEvent event, float x, float y) { 
       ((Game) Gdx.app.getApplicationListener()).dispose(); 
       ((Game) Gdx.app.getApplicationListener()).setScreen(new SceneB()); 
      } 
     }); 

     stage.addActor(button); 

     // don't forget to call this to be able to handle stage inputs 
     Gdx.input.setInputProcessor(stage); 
    } 

    // ........ here remaining methods (resize(), resume(), pause(), hide()) 
    @Override 
    public void dispose() { 
     stage.dispose(); 
     System.out.println("\ndispose SceneA"); 
    } 
}

の

、3-作成SceneB実装Screen：

public class SceneB implements Screen { 

    private Stage stage; 

    @Override 
    public void show() { 
     System.out.println("\nshow SceneB"); 

     stage = new Stage(new StretchViewport(1920, 1080)); 

     Image button = new Image(new Texture("____.png")); 
     button.addListener(new ClickListener() { 
      public void clicked(InputEvent event, float x, float y) { 
       ((Game) Gdx.app.getApplicationListener()).dispose(); 
       ((Game) Gdx.app.getApplicationListener()).setScreen(new SceneA()); 
      } 
     }); 

     stage.addActor(button); 

     // don't forget to call this to be able to handle stage inputs 
     Gdx.input.setInputProcessor(stage); 
    } 

    // ........ here remaining methods (resize(), resume(), pause(), hide()) 
    @Override 
    public void dispose() { 
     stage.dispose(); 
     System.out.println("\ndispose SceneB"); 
    } 
}

ありがとう！入力プロセッサーを設定するのを忘れてしまったようですが、1行のコードを追加するだけでうまく動作します！ – DaxHR
