Here're some resources for this part besides some in previous part (AnalogOnScreenControlExample):
Create new class named AnalogOnScreenControlsExample in the package org.anddev.andengine.examples of the AndEngineDemo project, here is the code of this class:
package org.anddev.andengine.examples;import javax.microedition.khronos.opengles.GL10;import org.anddev.andengine.engine.Engine;import org.anddev.andengine.engine.camera.Camera;import org.anddev.andengine.engine.camera.hud.controls.AnalogOnScreenControl;import org.anddev.andengine.engine.camera.hud.controls.AnalogOnScreenControl.IAnalogOnScreenControlListener;
Open the AndroidManifest.xml and insert the activity element below the previous activity element like this:import org.anddev.andengine.engine.camera.hud.controls.BaseOnScreenControl;import org.anddev.andengine.engine.handler.physics.PhysicsHandler;import org.anddev.andengine.engine.options.EngineOptions;import org.anddev.andengine.engine.options.EngineOptions.ScreenOrientation;import org.anddev.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;import org.anddev.andengine.entity.scene.Scene;import org.anddev.andengine.entity.scene.background.ColorBackground;import org.anddev.andengine.entity.sprite.Sprite;import org.anddev.andengine.entity.util.FPSLogger;import org.anddev.andengine.extension.input.touch.controller.MultiTouch;import org.anddev.andengine.extension.input.touch.controller.MultiTouchController;import org.anddev.andengine.extension.input.touch.exception.MultiTouchException;import org.anddev.andengine.opengl.texture.TextureOptions;import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;import org.anddev.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;import org.anddev.andengine.opengl.texture.region.TextureRegion;import org.anddev.andengine.util.MathUtils;import android.widget.Toast;/*** (c) 2010 Nicolas Gramlich* (c) 2011 Zynga** @author Nicolas Gramlich* @since 00:06:23 -

Run the project (in debug mode) to re-generate apk file in the bin folder<activity android:name=".AnalogOnScreenControlExample" android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN"/><category android:name="android.intent.category.LAUNCHER"/></intent-filter></activity><activityandroid:name=".AnalogOnScreenControlsExample"android:label="@string/app_name" ><intent-filter><action android:name="org.anddev.andengine.examples.ANALOGONSCREENCONTROLSEXAMPLE" /><category android:name="android.intent.category.DEFAULT" /></intent-filter></activity>
Open and Edit the batch command file named r.bat in the bin folder with some commands like this:
Then run the batch file r.bat
adb install -r AndEngineDemo.apkRun android emulator with virtualbox
adb shell am start -n org.anddev.andengine.examples/.AnalogOnScreenControlsExample
Then run the batch file r.bat
The result's like this
Here's the multitouch demo with 2 control base, you can both control the picture with some direction movement with the left and control by turning round the picture.
