Part 8. Creating loading scene:

Warning: If you are reading this article, and you were reading and using previous articles before today's date (21/01/2012) please BE AWARE of the fact that articles 4, 5 and 6 have been UPDATED and RE-FACTORED (please read them again and update your code, otherwise you will encourage many issues/errors) Those updates were necessary!

1. Loading scene:

• lets first create a loading scene class, lets call it LoadingScene. As previously, use our BaseScene class as an extension and add unimplemented methods.  Lets also create a white background for our scene.

package com.matimdev.scene;

import org.andengine.entity.scene.background.Background;
import org.andengine.util.adt.color.Color;

import com.matimdev.base.BaseScene;
import com.matimdev.manager.SceneManager.SceneType;

public class LoadingScene extends BaseScene
{
    @Override
    public void createScene()
    {
        setBackground(new Background(Color.WHITE));
    }

    @Override
    public void onBackKeyPressed()
    {
        return;
    }

    @Override
    public SceneType getSceneType()
    {
        return SceneType.SCENE_LOADING;
    }

    @Override
    public void disposeScene()
    {

    }
}

As you probably noticed, inside onBackKeyPressed() we just return, which means we do not perform any actions (because we do not want to do anything while the loading scene is being displayed and the player touches the phone`s back button)

3. Creating "loading..." text:

• Open our ResourcesManager class, lets create a new method responsible for loading our Font, we also create our Font in a public field.

public Font font;

private void loadMenuFonts()
{
    FontFactory.setAssetBasePath("font/");
    final ITexture mainFontTexture = new BitmapTextureAtlas(activity.getTextureManager(), 256, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);

    font = FontFactory.createStrokeFromAsset(activity.getFontManager(), mainFontTexture, activity.getAssets(), "font.ttf", 50, true, Color.WHITE, 2, Color.BLACK);
    font.load();
}

• Now lets execute our method responsible for loading fonts inside the loadMenuResources() method, so it should now look like this:

public void loadMenuResources()
{
    loadMenuGraphics();
    loadMenuAudio();
    loadMenuFonts();
}

@Override
public void createScene()
{
    setBackground(new Background(Color.WHITE));
    attachChild(new Text(400, 240, resourcesManager.font, "Loading...", vbom));
}

• Initialize the loading scene inside our SceneManager, inside createMenuScene()

public void createMenuScene()
{
    ResourcesManager.getInstance().loadMenuResources();
    menuScene = new MainMenuScene();
    loadingScene = new LoadingScene();
    SceneManager.getInstance().setScene(menuScene);
    disposeSplashScene();
}
