I'm fairly new to AndEngine Android programming and I don't know how to convert my SimpleBaseGameActivity code to BaseGameActivity. I want to convert it to match the tutorial i found on BaseGameActivity Splash + Menu tutorial so that I'll be able to merge it all.
Here's the code for the Tower of Hanoi Game:
public class MainActivity extends SimpleBaseGameActivity {
private ITexture main_font_texture;
Text countText;
Font main_font;
int movesCount;
Scene scene = new Scene();
private static int CAMERA_WIDTH = 800;
private static int CAMERA_HEIGHT = 480;
private ITextureRegion mBackgroundTextureRegion, mTowerTextureRegion, mRing1, mRing2, mRing3;
private Stack<Ring> mStack1, mStack2, mStack3;
private Sprite mTower1, mTower2, mTower3;
@Override
public EngineOptions onCreateEngineOptions() {
final Camera camera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), camera);
}
@Override
protected void onCreateResources() {
try {
main_font = FontFactory.create(this.getFontManager(), this.getTextureManager(), 256, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA, Typeface.DEFAULT, 60, true, Color.BLACK_ABGR_PACKED_INT);
main_font.load();
ITexture backgroundTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/background.png");
}
});
ITexture towerTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/tower.png");
}
});
ITexture ring1 = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {

Here's for the Ring.java :
@SuppressWarnings("unused")
public class Ring extends Sprite {
private int mWeight;
private Stack<Ring> mStack; //this represents the stack that this ring belongs to
private Sprite mTower;
public Ring(int weight, float pX, float pY, ITextureRegion pTextureRegion, VertexBufferObjectManager pVertexBufferObjectManager) {
super(pX, pY, pTextureRegion, pVertexBufferObjectManager);
this.mWeight = weight;
}
public int getmWeight() {
return mWeight;
}
public Stack<Ring> getmStack() {
return mStack;
}
public void setmStack(Stack<Ring> mStack) {
this.mStack = mStack;
}
public Sprite getmTower() {
return mTower;
}
public void setmTower(Sprite mTower) {
this.mTower = mTower;
}
}
