我正在AndEngine中练习。
我制作了一个背景,一个精灵,并添加了运动和重力。
所以我决定对背景音乐和声音进行一些练习,但是我遇到了问题。现在,当我启动该应用程序时,我得到了黑屏,并且精灵扭曲了,当然音乐不响了。
你能帮我吗?这是代码:
public class MainActivity extends BaseGameActivity {
Scene scene;
private Music music;
protected static final int CAMERA_WIDTH = 850;
protected static final int CAMERA_HEIGHT = 480;
BitmapTextureAtlas playerTexture;
ITextureRegion playerTexureRegion;
PhysicsWorld physicsWorld;
@Override
public EngineOptions onCreateEngineOptions() {
// TODO Auto-generated method stub
Camera mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
EngineOptions options = new EngineOptions(true,
ScreenOrientation.LANDSCAPE_FIXED, new FillResolutionPolicy(), mCamera);
return options;
}
@Override
public void onCreateResources(
OnCreateResourcesCallback pOnCreateResourcesCallback)
throws Exception {
// TODO Auto-generated method stub
loadGfx();
loadSounds();
// resource
pOnCreateResourcesCallback.onCreateResourcesFinished();
}
private void loadSounds() {
// TODO Auto-generated method stub
try
{
music = MusicFactory.createMusicFromAsset(mEngine.getMusicManager(), this,"mfx/oldf.ogg");
}
catch (IOException e)
{
e.printStackTrace();
}
}
private void loadGfx() {
// TODO Auto-generated method stub
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
// width and height power of 2^x
playerTexture = new BitmapTextureAtlas(getTextureManager(), 64, 64);
playerTexureRegion = BitmapTextureAtlasTextureRegionFactory
.createFromAsset(playerTexture, this, "player.png", 0, 0);
playerTexture.load();
}
@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
throws Exception {
this.scene = new Scene();
this.scene.setBackground(new Background(0.09804f, 0.6274f, 0.8784f));
this.music.play();
physicsWorld = new PhysicsWorld(new com.badlogic.gdx.math.Vector2(0, SensorManager.GRAVITY_EARTH), false);
this.scene.registerUpdateHandler(physicsWorld);
createWalls();
pOnCreateSceneCallback.onCreateSceneFinished(this.scene);
}
private void createWalls() {
// TODO Auto-generated method stub
FixtureDef WALL_FIX = PhysicsFactory.createFixtureDef(0.0f, 1.0f, 0.0f);
Rectangle ground = new Rectangle(0, CAMERA_HEIGHT - 15, CAMERA_WIDTH,
15, this.mEngine.getVertexBufferObjectManager());
ground.setColor(new Color(15, 50, 0));
PhysicsFactory.createBoxBody(physicsWorld, ground, BodyType.StaticBody,
WALL_FIX);
this.scene.attachChild(ground);
}
@Override
public void onPopulateScene(Scene pScene,
OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
// TODO Auto-generated method stub
Sprite sPlayer = new Sprite(CAMERA_WIDTH / 2, CAMERA_HEIGHT / 2,
playerTexureRegion, this.mEngine.getVertexBufferObjectManager());
sPlayer.setRotation(45.0f);
final FixtureDef PLAYER_FIX = PhysicsFactory.createFixtureDef(10.0f,
1.0f, 0.0f);
Body body = PhysicsFactory.createCircleBody(physicsWorld, sPlayer,
BodyType.DynamicBody, PLAYER_FIX);
this.scene.attachChild(sPlayer);
physicsWorld.registerPhysicsConnector(new PhysicsConnector(sPlayer,
body, true, false));
pOnPopulateSceneCallback.onPopulateSceneFinished();
}
谢谢!

最佳答案
OOOoooo我现在知道您的问题,将其添加到您的EngineOptions类中
options.getAudioOptions().setNeedsMusic(true);
options.getAudioOptions().setNeedsSound(true);
启动
EngineOptions
时,必须指出您将需要场景声音。您对EngineOptions
方法进行了轻微的疏忽。
