BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset can not find bitmap files when file has underscores in the name #53

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Try to load a bitmap file with underscore _ in the name:

    @Override
    public void onLoadResources() {

        this.mTexture = new BitmapTextureAtlas(256, 256, TextureOptions.BILINEAR_PREMULTIPLYALPHA);

        // Create the ball:
        this.mBallTextureRegion = BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset(this.mTexture, this, "gfx/ui_ball.png", 0, 0, 2, 4);

        // Create the player:
        this.mPlayerTextureRegion = BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset(this.mTexture, this, "gfx/uiPlayer.png", 128, 0, 2, 4);

        this.mEngine.getTextureManager().loadTexture(this.mTexture);
    }

ui_ball.png triggers the following error:

When file is renamed it works fine.
I'm using latest version from the trunk

when i add files and build a sample, i got the same problem. But when i rename 
file to other name and revert it back, than all works fine. i think its not 
appengine source problem, it is something with eclipse resources update or 
something else. i'm newbie in android programming so maybe i'm wrong.

Hi all.
I think that the reason of the error has been caused by the code which opening 
asset file.
Please look code below.

http://code.google.com/p/andengine/source/browse/src/org/anddev/andengine/opengl
/texture/atlas/bitmap/source/AssetBitmapTextureAtlasSource.java?r=ea4ff643a0e588
57e92738a6e5449b6a362190cd#55
54: try {
  :-        in = pContext.getAssets().open(pAssetPath);
  :+        in = pContext.getAssets().open(BitmapTextureAtlasTextureRegionFactory.sAssetBasePath + pAssetPath);
56:     BitmapFactory.decodeStream(in, null, decodeOptions);

The origin code has not considered behaviour which does not contain the 
assetBasePath.
