After updating from the version where vertex buffers were added to entities and moving to the newest version my fonts lost their outer stroke. I thought it was an issue on my end but the newest examples seem to have the same issue. One other person that I know of is also having this issue.

I got this errors.

I'm having this error where my Live Wallpaper freezes randomly. Sometimes it takes a few minutes, sometimes when the phone wakes or I do something fast.
I've been looking for this and found others with similar problems like this one:

http://stackoverflow.com/questions/5814002/cpu-may-be-pegged-opengl-live-wallpaper-locks-up

It pointed me to those 2 links:

markfguerra/GLWallpaperService#11

Is it possible that we have the same issues as them?

Hello there,

Just some thing I've noticed while developing my app: Sometimes the OrientationListener just doesn't initialize that well. It doesn't really work correctly at all sometimes. i.e. when tilting it to the right (change of roll) it doesn't recognize that correctly. After restarting the app (finish() and then start it again) normally everything is back to normal and works).

Which leads me to the question:

Is the OrientationSensor stuff being calibrated on each startup (maybe this causes this problem?)? But I don't really think so. Maybe it's a hardware bug on my side.

I think there is something wrong with the ParticleSystem in GLES2 version of the AndEngine. Even i run the AndEngineExamples project on my phone, i see the FPS is around 7-8 at ParticleSystem examples.

Getting this very often (but still intermittently)

Comes in a few flavours

I imported AndEngine from git (gles2) but Eclipse shows many errors:

1. gen folder is missing (ok I added this manually)
2. Buildconfig cannot be resolved to a variable (this error occurs many times)
3. The container 'Library Projects' references non existing library 'XXXX/git/AndEngine/bin/andengine.jar' (xxxx is a path)
4. The import org.andengine.BuildConfig cannot be resolved (this error occurs many times)

Some characters, it seems punctuation symbols in particular, do not have their width's measured correctly by FontUtils.

Expected result: Red rectangle lines up with text width.

Actual result: Perfect for the first string ("TEST"), but too short for the second string ("TEST.").

Text t = new Text(100f, 100f, theme.getMainFont().getFont(), "TEST", getVertexBufferObjectManager());
Rectangle r = new Rectangle(ct.getX(), ct.getY(), ct.getWidth(), ct.getHeight(), getVertexBufferObjectManager());
r.setColor(Color.RED);

scene.attachChild(r);
scene.attachChild(t);

t = new Text(100f, 100f, theme.getMainFont().getFont(), "TEST.", getVertexBufferObjectManager());
r = new Rectangle(ct.getX(), ct.getY(), ct.getWidth(), ct.getHeight(), getVertexBufferObjectManager());
r.setColor(Color.RED);

scene.attachChild(r);
scene.attachChild(t);

First Thanks a lot for this awesome Engine, it helped me very much
Second,
i have used the onKeyDown to handle the back button to pause my game :

if((pKeyCode == KeyEvent.KEYCODE_MENU || pKeyCode == KeyEvent.KEYCODE_BACK  && pEvent.getAction() == KeyEvent.ACTION_DOWN) )
    {
        handlePausing();
    }

the menu button worked fine , but the back button exits the game not pause? how i can solve it

Hello there,

I've switched back to the GLES2 version and now that ChangeableText is gone, I am using Text, but this seems to make the game crash. I don't know when and why, but I will investigate if it's not a misusage of Text that causes crashing. Or to make it precise: Should setText(...) be used on Text objects? Because I get an ArrayIndexOutOfBounds Exception because of that.

I think the issue #33 may not be 100% fixed. I am having the same problem where old letters are being displayed on top or after a text (TickerText in my case) after it has been set to a new string. This occurs when the string is smaller or even larger than the previous string, with random letters appearing in the same space as the new letter.
I have checked that there is nothing wrong with the actual string by outputting it to the log.
Also, the problem is possibly occuring more often when the tick speed is higher (i.e. 60 instead of 15).

Here are some screen shots:

The example EntityModifierExample only shows black box, and always you use alpha.

Edit: The broken modifier is AlphaModifier
Edit2: It seems that all alpha is broken.

Hi, I found a bug appearing when I use compass.

First I add compass in my app:

@Override
    public void onLoadComplete() {
        this.enableOrientationSensor(this);
    }

Then implement method "onOrientationChanged"

@Override
    public void onOrientationChanged(OrientationData pOrientationData) {
pOrientationData

pOrientationData.getYaw() //compass
pOrientationData.getPitch() //one orientation axis
pOrientationData.getRoll() //other orientation axis

}

Then there is a problem which happens spontaneously and SOMETIMES.
I don't know how to provoke the bug yet (except of many attempts to restart the app until success).

The bug has 3 symptoms:

1. Compass returns wrong direction - 90 degrees different from correct.
2. "Pitch" function returns Roll values
3. "Roll" function returns Pitch values

(Samsung Galaxy S GTI-9000)

This is it.

Now the Changeable Text is missing, or is there an other Implementation to use instead?

EDIT: Originally I posted this problem without digging into it and have found out where the problem stems from and what the effects are.

The problem is simply initial textures are not appearing on the screen. Anything that would be attached during the activity launch, for example a background image, would be invisible. It is apparent that the sprites are being drawn, the resources are just missing.

After some snooping around I've come up with some behaviour that I'm sure is the cause of this problem. Here's a link to the post regarding what I've come up with so far for this problem: http://www.andengine.org/forums/gles2/resume-activity-no-texture-reload-maybe-a-bug-t6167.html#p27523

I cloned a new fresh AndEngineExample and have some errors.

ex:
import org.andengine.input.sensor.accelerometer.AccelerometerData;
import org.andengine.input.sensor.accelerometer.IAccelerometerListener;

replace every "accelerometer" by "acceleration" and every "Accelerometer" by "Acceleration"

Search "accelerometer" (18 hits in 9 files)
Search "Accelerometer" (90 hits in 9 files)

After that i have "The type BoundCameraExample must implement the inherited abstract method IAccelerationListener.onAccelerationAccuracyChanged(AccelerationData)"

Eclipse Quick fix worked for that

When you press power button in game the device locks and after unlock it with power button AndEngine reinitialize the whole game and resources and all the level progress is lost. (When you use "home button" and return to the game all the game is on the last state and progress is saved). Is it possible to prevent reinitializing of resources (if android doesn't kill the activity)? (there is a way to save the state with xml\json etc but i think it is not the best solution).

I found that "setAlpha" works incorrect for Particles with AlphaParticleInitializer. It's better to remove IF condition like this:

WAS:

@OverRide
public void setAlpha(final float pAlpha) {
if(this.mColor.setAlphaChecking(pAlpha)) {
this.onUpdateColor();
}
}

SHOULD BE:

@OverRide
public void setAlpha(final float pAlpha) {
this.mColor.setAlphaChecking(pAlpha);
this.onUpdateColor();
}

Hi

I found a strange problem about textures.

To demonstrate it I've created the next two textures:
1 - some complex image
http://jfixbi.files.wordpress.com/2012/01/mid_1.png

2 - a rectangle, filled with the next color:
http://jfixbi.files.wordpress.com/2012/01/front_11.png

Simple code:

protected Scene onCreateScene() {

            this.mEngine.registerUpdateHandler(new FPSLogger());
            this.mScene = new Scene();

            Sprite mountains = new Sprite(0, 0, this.mid_1_png);
            Sprite rectangle = new Sprite(0, 0, this.front_11_png);

            mScene.attachChild(mountains);
            mScene.attachChild(rectangle);

            return mScene;
    }

Here is the result:

http://jfixbi.files.wordpress.com/2012/01/sc20120118-002245.png

Looks like the mountains is visible through the rectangle (in the left part of the image).

Maybe It is hard to see so I increase contrast to get something like this:

I have class which extends Entity and implements Scene.ITouchArea.
My implementation of method ITouchArea.contains(float pX, float pY) returns result of

RectangularShapeCollisionChecker.checkContains(this, 500, 500, pX, pY);

I think that first two params (x,y) of call

RectangularShapeCollisionChecker.fillVertices(pEntity.getX(), pEntity.getY(), pLocalWidth, pLocalHeight, ...);

should be 0,0 as it is in method checkContains with RectangularShape as param.

Hello there,

I have been messing around with andengine examples, i have downloaded the last version of andengine branch GLES2, exported it and tested it with 2 devices.

The first multiplayer example i tested, was the one that makes faces appear when you touch, but when i connected both devices, no faces appeared in phones.

The other one, the pong example, worked better, but i had to click connect fast or the example would close if the ball reaches the other side. Also, when both players are playing, it closes randomly, from 15 seconds to 50, maybe due to wifi packet loss(I was testing it using a third device as ad hoc).

I would like to use the andengine multiplayer extension, and i would like to know the limits of this extension and how much would i have to work on it to have it functional.

I had an issue where I was moving the camera, and adding sprites to the scene. I registered those sprites as touch areas, however the touch listener was not being called. The CameraScene class is translating the CameraScene coordinates in to screen coordinates, and hence not registering the touches on the sprites that had been registered 'off screen'.

The code is in org.anddev.andengine.engine.camera.Camera, line 313:

public void convertSceneToCameraSceneTouchEvent(final TouchEvent pSceneTouchEvent) {

        this.unapplySceneRotation(pSceneTouchEvent);

        this.applySceneToCameraSceneOffset(pSceneTouchEvent);

        this.applyCameraSceneRotation(pSceneTouchEvent);
}

I added a boolean flag to the camera class to switch this on and off, and it seems to work fine. Related form post here: http://www.andengine.org/forums/gles1/registered-toucharea-moves-with-camera-t5018.html

I have a gaming Issue :

I have two Physicsworld :

1. It has no gravity
2. It has Gravity

I like to Do:

I want to use the gravity of the 2nd World to drop the object from something and then disconnect from it's world and connect to the 1st world ...

I need exact as I described above to accomplish my need ...

so how can I add one body from one PhysicsWorld to Another in Android ???

-Thanks for Viewing

I think there is some issue with this line of code in class AnimatedSprite:

this.mAnimationListener.onPerformedFrameAnimation(currentFrameIndex);

It would be better to check if this.mAnimationListener is null or not, when calling onPerformedFrameAnimation. Otherwise, NullPointerException might be thrown.

if you run this code. x will be equal to 2 instead of 1

int x=0;
Sprite mSprite = new Sprite(0,0,Textures,new VertexBufferObjectManager())   {
            @Override
            public boolean onAreaTouched(TouchEvent pSceneTouchEvent,
                    float pTouchAreaLocalX, float pTouchAreaLocalY){
                if (pSceneTouchEvent.getAction() == TouchEvent.ACTION_UP)
                          x++;
                return super.onAreaTouched(pSceneTouchEvent, pTouchAreaLocalX, pTouchAreaLocalY);
            }};
registerTouchArea(mSprite);
registerTouchArea(mSprite);

After using setBlendFunction() on sprite it doesn't changes alpha. If I set alpha(0f) - nothing happens. But without using setBlendFunction() it works.

when pPerformSameTextureSanityCheck is set to true and not all supplied ITextureRegion are same, deepCopy method will throw exception.

After loading a LWP and then returning to it from another activity the system seems to load the texture atlas' instead of the texture regions.

See video below for better description

Reported by @sjvc :

This is the code:

Text text1 = new Text(2, 100, myFont, "ThisIsTextWithoutWhiteSpaces", this.getVertexBufferObjectManager());
text1.setText("This has white spaces");
myScene.attachChild(text1);

Text text2 = new Text(2, 200, myFont, "This has white spaces", this.getVertexBufferObjectManager());
myScene.attachChild(text2);

This screenshot shows "weird result": http://i39.tinypic.com/9lehj4.png
This screenshot shows expected result after remove "if(!letter.isWhitespace())": http://i41.tinypic.com/xdxx5v.png

I don't know the correct way to solve it

Hi.

There is serious issue when we use PhysicalWorld: bodies has problems with updating sprites positions.
That's why moving sprites perform "jumping" during movement.

Looks like a general bug (in architecture) appearing because of difference in time intervals inside onUpdate for the Engine and for the World. Probably it is necessary to redesign the way of using the Box2d.

Here is the code to demonstrate the bug. The flowing is a modification of the FixedStepPhysics example.
I removed walls and add one body falling in the gravity field.

There you can see how the sprite is jumping during movement.

Also it demonstrates the "velocity=double-frame-rate" bug ( see: nicolasgramlich/AndEnginePhysicsBox2DExtension#3 ).

When using this import: import "org.andengine.util.color.Color;" The code does't work, but when using this "android.graphics.Color" works perfectly

/* Load the font we are going to use. */
FontFactory.setAssetBasePath("font/");
final ITexture plokFontTexture = new BitmapTextureAtlas(this.getTextureManager(), 256, 256, TextureOptions.BILINEAR);
Game.this.mDefaultFont = FontFactory.createFromAsset(this.getFontManager(), plokFontTexture, this.getAssets(), "Plok.ttf", 32f, true, Color.WHITE);
Game.this.mDefaultFont.load();

And gets this message:
The method createFromAsset(FontManager, ITexture, AssetManager, String, float, boolean, int) in the type FontFactory is not applicable for the arguments (FontManager, ITexture, AssetManager, String, int, boolean, Color)

I have for my game several sprites with physic bodies for the ground on which the player is running. when i stand still the sprites are displayed correctly nearby each other without distance. But when i move the player and the camera followes the player ther always are distances shown between the sprites.
I have tried all variations of textureoptions and distances in the atlas but nothing fixed the problem.

I have uploaded some screen shots in the forum of andengine at topic:

http://www.andengine.org/forums/bugs-gles2/showing-distance-between-sprites-when-camera-moves-t7105.html

In the method onPause() of class BaseGameActivity call the method onPauseGame(), which stop the engine, however, the method onResume() does not call onResumeGame() and therefore the engine is stopped, and therefore the game is blocked.

I tried overwriting the onPause () with:

onResume public void () {
super.onResume ();

if (isGamePaused ())
onResumeGame ();
}

and now works fine.

Issue: When having an AnimatedSprite bounce around in a PhysicsWorld by setting gravity and turning the device, sometimes it will FC throwing an IndexOutOfBoundsException to the logcat.
Expected: Not to have this issue

Temporary Patch: http://pastebin.com/d1kExwzB

I don't believe this is the best way to fix it since there is an underlying cause. This is just a band-aid. However, it works for my needs currently, and I am strapped for time otherwise I would dig deeper. I haven't checked to see if this is fixed on the GLES2 branch.

Hello there. Sometimes it occurs that in BaseGameActivity this part here:

@Override
   public void onResumeGame() {
      Debug.d(this.getClass().getSimpleName() + ".onResumeGame" + " @(Thread: '" + Thread.currentThread().getName() + "')");

      this.mEngine.start();

      this.mGamePaused = false;
   }

is being executed without mEngine being initialized (at game startup).

sake

There is a strange problem: looks like a sum of two equal forces with opposite directions is not equal to zero.

First of all I use FixedStepPhysics example.
Then I change it for to I apply a force on a single body.

The force is equal but fully opposite to the gravity.

[syntax="java"]

...
this.mPhysicsWorld = new FixedStepPhysicsWorld(30, new Vector2(0,
            10f), false, 3, 2);

...
}

.....
Vector2 Launch = new Vector2(0, -10f);
Vector2 Rocket = new Vector2(0, 0);

@Override
public void onUpdate(float pSecondsElapsed) {
    // TODO Auto-generated method stub
    if (go) {
        Rocket = body.getPosition();
        body.applyForce(Launch, Rocket);
    }
}

[/syntax]

So, when I run the example the body flies UP.
Moreover It is necessary to apply about а "Launch = new Vector2(0, -10f*0.41а);" force
to get the zero-gravity state for the body.

So basically, assuming that the engine works fine we conclude that 0.41f = 1f :)

Here is the full code of the activity, so you can check if I'm wrong:

Just cloned the latest and the examples don't compile. The issue is because you made a change to the textures where they take the texturemanager as a paramater.

My issue is bigger than this change though, since you have a single branch in your project every change you make has the possibility of breaking everything. The preferred solution here is to have multiple branches in for both AndEngine and the examples (a stable and a dev branch). Please branch your project to have a stable release that we (external developers) can rely on without issue and a branch for yourself where you make bugfixes/major changes and push to the stable as needed.

This occurs on particular devices. I'm guessing the native library for the chipset can't be found?
It's not proguard or anything like that, it's a native library not being found.

These are the devices I've found so far:
Fujitsu Toshiba REGZA Phone T01C(tg03)

Pantech Vega X(ef14l)
Pantech IS06(jmasai)

I've looked into Andengine-Examples, and it suggested to change Texture itself into other TextureRegiond. However, in my

opinion, this is not a very effective way when considering the use of resource.

Is any way to change the tiledTextureRegion of animatedSprite at a time when I want?

Someone sent me that error report of my game (Juggle The Doodle):

When resuming from a normal Activity to an AndEngine based one there is a noticeable delay in the default Android view transition. Although the AndEngine activity calls its onResume immediately, the system doesn't "pop" the old Activity off until AndEngine is able to draw the scene. On some devices this results in a delay long enough (~2 seconds) that the user believes that he/she didn't actually hit the back button and presses it again, which will pop the AndEngine activity off the stack.

This behavior is new to the OpenGL ES 2 branch, on ES 1 the normal Activity would be removed immediately and a black screen would appear before the engine was ready to draw again. I preferred the old behavior because the user's action (pressing back) was immediately recognized.

Is there anyway to prevent this delay in the ES 2 branch and force the window transition immediately?

Running on Samsung Galaxy S2, with Android 2.3.6. When I press home button, game goes background, and AndEngine calls onPauseGame and immediately onResumeGame. When I resume the game, onResumeGame is not called.

The problem is in BaseGameActivity, when onWindowFocusChanged event is called, for some reason pHasWindowFocus is true, and onResumeGame is called.

I tried to debug, I added the "Debug.d" line:

@Override
public synchronized void onWindowFocusChanged(final boolean pHasWindowFocus) {
    super.onWindowFocusChanged(pHasWindowFocus);

    Debug.d("pHasWindowFocus:" + String.valueOf(pHasWindowFocus));

    if(pHasWindowFocus && this.mGamePaused && this.mGameCreated) {
        this.onResumeGame();
    }
}

And this is the log I get when I press home button:

02-10 20:04:47.640: D/AndEngine(29438): DoodleJuggleActivity.onPause @(Thread: 'main')
02-10 20:04:47.680: D/AndEngine(29438): DoodleJuggleActivity.onPauseGame @(Thread: 'main')
02-10 20:04:47.725: D/AndEngine(29438): pHasWindowFocus:false
02-10 20:04:47.730: D/AndEngine(29438): pHasWindowFocus:true
02-10 20:04:47.730: D/AndEngine(29438): DoodleJuggleActivity.onResumeGame @(Thread: 'main')
02-10 20:04:47.730: D/AndEngine(29438): pHasWindowFocus:false

Seems that onWindowFocusChanged is called more than once...

Just insert this code into the org.andengine.util.color.Color

//;-------------------------------------------

public static final int FF_VALUE = 0XFFFFFFFF;
public static final int VALUE_255 = 255;
public static final int VALUE_24 = 24;
public static final int VALUE_16 = 16;
public static final int VALUE_8 = 8;

private void pack() {
final int packed = ((int) (VALUE_255 * this.mAlpha) << VALUE_24)
| ((int) (VALUE_255 * this.mBlue) << VALUE_16)
| ((int) (VALUE_255 * this.mGreen) << VALUE_8)
| ((int) (VALUE_255 * this.mRed));
this.mPacked = Float.intBitsToFloat(packed & FF_VALUE);
}

public static float pack(final float pRed, final float pGreen,
final float pBlue, final float pAlpha) {
final int packed = ((int) (VALUE_255 * pAlpha) << VALUE_24)
| ((int) (VALUE_255 * pBlue) << VALUE_16)

return Float.intBitsToFloat(packed & FF_VALUE);

Hi, community!

Sorry for open issue here, but i don't know where it's write.

Problem: AndEngine is not supporting Samsung Galaxy 3 (Samsung GT-I5800). Concerns GLES1 and GLES2.
All games from Android Market has a white textures, such as Bunny Shooter and many others.

Given that this is still not quite a bad phone - I think this is a big problem. How can I help in correcting this problem? Is it possible somehow to fix?

Thanks in advance. I hope for your understanding.

P.s. I recently opened topic at forum with video and screenshots, but none has yet been able to help -> (http://www.andengine.org/forums/gles1/how-to-completly-unload-scene-and-her-resources-t5609.html)

I've noticed something I don't like. The remove method which is passed a reference of an Object normally just removes the given object reference from the List. That's all. Then why do it with a Generic? The default Java Implementation does this and removing something from the list doesn't need a cast and makes code more "uncrashy". Just look at this (from my code):

                public void onModifierFinished(IModifier<IEntity> pModifier, IEntity pItem) {
                    LevelSceneHandler.this.mCue.remove((BlockSprite)pItem);
                    LevelSceneHandler.this.mBlockSpritePool.recyclePoolItem((BlockSprite) pItem);
                }

What if this code is called on an Entity that is no BlockSprite? It will cause an ClassCastException (afaik) instead of not doing anything (which is imo better in this case). And I don't have to use an useless cast.

So why not change the remove method to remove(Object) in all collections?

Hi Nicolas,

I'm using the source code compiled AndEngine to develop a game. But I found it seems onAreaTouched on Sprite has problem.
My game will add about 30 new sprites in that event once touch a special Sprite, but the problem is the screen will hangup when I tapped about 15 times on it.

I checked the TouchDragExample.java in the AndEngineExamples project, found it also show below msg in log when tap that sprite. Is that normal?

03-21 15:25:19.534: V/AndEngine(17152): org.andengine.input.touch.TouchEvent$TouchEventPool was exhausted, with 0 item not yet recycled. Allocated 1 more.
03-21 15:25:19.534: V/AndEngine(17152): org.andengine.util.adt.pool.PoolUpdateHandler$1 was exhausted, with 0 item not yet recycled. Allocated 1 more.

--Updated later
On my another machine, I kept a copy of your source code about 7 weeks ago (labeled as "Bad-ass package refactoring org.anddev.util and related classes/packages (only moved classes around so their new package makes more sense). SortedQueue is now a wrapper encapsulating another IQueue, instead of being a subclass to another specific Queue implementation -> allows for better reusability without duplicating code."). I can ran my same code successfully based on it, although I still can find above msg, but it just appear occasionally.

Hope the new finding are helpful.

Thanks & Regards
