<p>I am trying to add particle effect in my game. No error but showing logcat when running. Below is my code and logcat.</p> <pre><code>@Override public void onLoadResources() { //prepare a container for particle mParticleBitmapTextureAtlas = new BitmapTextureAtlas(32, 32, TextureOptions.BILINEAR_PREMULTIPLYALPHA); // setting assets path for easy access BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/"); mParticleTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mParticleBitmapTextureAtlas, this, "particle_fire.png", 0,0); // loading textures in the engine mEngine.getTextureManager().loadTexture(this.mParticleBitmapTextureAtlas); } @Override public Scene onLoadScene() { mEngine.registerUpdateHandler(new FPSLogger()); mMainScene = new Scene(); mMainScene.setBackground(new ColorBackground(0f, 0f, 0f)); //particle system /* Left to right Particle System. */ { final ParticleSystem particleSystem = new ParticleSystem(new PointParticleEmitter(0, CAMERA_HEIGHT), 6, 10, 70, this.mParticleTextureRegion); particleSystem.setBlendFunction(GL10.GL_SRC_ALPHA, GL10.GL_ONE); particleSystem.addParticleInitializer(new VelocityInitializer(15, 22, -60, -90)); particleSystem.addParticleInitializer(new AccelerationInitializer(5, 15)); particleSystem.addParticleInitializer(new RotationInitializer(0.0f, 360.0f)); particleSystem.addParticleInitializer(new ColorInitializer(1.0f, 0.0f, 0.0f)); particleSystem.addParticleModifier(new ScaleModifier(0.5f, 2.0f, 0, 5)); particleSystem.addParticleModifier(new ExpireModifier(11.5f)); particleSystem.addParticleModifier(new AlphaModifier(1.0f, 0.0f, 2.5f, 3.5f)); particleSystem.addParticleModifier(new AlphaModifier(0.0f, 1.0f, 3.5f, 4.5f)); particleSystem.addParticleModifier(new ColorModifier(1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f, 11.5f)); particleSystem.addParticleModifier(new AlphaModifier(1.0f, 0.0f, 4.5f, 11.5f)); this.mMainScene.getLastChild().attachChild(particleSystem); } return mMainScene; } </code></pre> <p>////////////////////logcat///////////////////////</p> <pre><code> 06-11 18:51:59.588: E/AndroidRuntime(1539): FATAL EXCEPTION: main 06-11 18:51:59.588: E/AndroidRuntime(1539): java.lang.NullPointerException 06-11 18:51:59.588: E/AndroidRuntime(1539): at com.example.AndEngineTest.AndEngineTest.onLoadScene(AndEngineTest.java:251) 06-11 18:51:59.588: E/AndroidRuntime(1539): at org.anddev.andengine.ui.activity.BaseGameActivity.doResume(BaseGameActivity.java:169) 06-11 18:51:59.588: E/AndroidRuntime(1539): at org.anddev.andengine.ui.activity.BaseGameActivity.onWindowFocusChanged(BaseGameActivity.java:85) 06-11 18:51:59.588: E/AndroidRuntime(1539): at com.android.internal.policy.impl.PhoneWindow$DecorView.onWindowFocusChanged(PhoneWindow.java:2366) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.view.View.dispatchWindowFocusChanged(View.java:5735) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:851) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2557) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.os.Handler.dispatchMessage(Handler.java:99) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.os.Looper.loop(Looper.java:137) 06-11 18:51:59.588: E/AndroidRuntime(1539): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-11 18:51:59.588: E/AndroidRuntime(1539): at java.lang.reflect.Method.invokeNative(Native Method) 06-11 18:51:59.588: E/AndroidRuntime(1539): at java.lang.reflect.Method.invoke(Method.java:511) 06-11 18:51:59.588: E/AndroidRuntime(1539): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-11 18:51:59.588: E/AndroidRuntime(1539): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-11 18:51:59.588: E/AndroidRuntime(1539): at dalvik.system.NativeStart.main(Native Method) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
