Font with shadows crashes

[fgnm]

When I set shadow parameters in FreeTypeFontParameter the app crashes.

Here is a sample code:

    private void createFonts() {
        FreeTypeFontGenerator.setMaxTextureSize(1024);

        FreeTypeFontGenerator fontGenerator = mAssetManager.get(mTextFontDesc);
        FreeTypeFontGenerator.FreeTypeFontParameter fontParameter;
        BitmapFont font;

        fontParameter = new FreeTypeFontGenerator.FreeTypeFontParameter();
        fontParameter.size = 64;
        //fontParameter.shadowColor = Color.BLACK;
        //fontParameter.shadowOffsetX = 6;
        //fontParameter.shadowOffsetY = 6;
        fontParameter.genMipMaps = true;
        fontParameter.minFilter = Texture.TextureFilter.MipMapLinearNearest;
        fontParameter.magFilter = Texture.TextureFilter.MipMapLinearNearest;

        font = fontGenerator.generateFont(fontParameter);
        font.setUseIntegerPositions(true);

        mMainTitleFontStyle = new Label.LabelStyle(font, new Color(0xf9f901ff));
    }

If I uncomment any of shadow parameter GWT application crashes with the following error:
Error: java.lang.RuntimeException: java.lang.ClassCastException.

I'm really confused about that.. what could be the cause?

Please create a minimal runnable example.

Well, it is a very basic asset manager class:

public class Assets {
    private final AssetDescriptor<FreeTypeFontGenerator> mTextFontDesc = new AssetDescriptor<FreeTypeFontGenerator>("font/Mecha_Bold.ttf", FreeTypeFontGenerator.class);

    private AssetManager mAssetManager;
    public Label.LabelStyle mMainTitleFontStyle;

    public Assets() {
        mAssetManager = new AssetManager();
        mAssetManager.setLoader(FreeTypeFontGenerator.class, new FreeTypeFontGeneratorLoader(new InternalFileHandleResolver()));
        mAssetManager.setLoader(BitmapFont.class, ".ttf", new FreetypeFontLoader(new InternalFileHandleResolver()));
    }

    public void createAssets() {
        //Skip all other assets
        createFonts();
    }

    private void createFonts() {
        FreeTypeFontGenerator.setMaxTextureSize(1024);

        FreeTypeFontGenerator fontGenerator = mAssetManager.get(mTextFontDesc);
        FreeTypeFontGenerator.FreeTypeFontParameter fontParameter;
        BitmapFont font;

        fontParameter = new FreeTypeFontGenerator.FreeTypeFontParameter();
        fontParameter.size = 64;
        //fontParameter.shadowColor = Color.BLACK;
        //fontParameter.shadowOffsetX = 6;
        //fontParameter.shadowOffsetY = 6;
        fontParameter.genMipMaps = true;
        fontParameter.minFilter = Texture.TextureFilter.MipMapLinearNearest;
        fontParameter.magFilter = Texture.TextureFilter.MipMapLinearNearest;

        font = fontGenerator.generateFont(fontParameter);
        font.setUseIntegerPositions(true);

        mMainTitleFontStyle = new Label.LabelStyle(font, new Color(0xf9f901ff));
    }

    public void dispose() {
        mAssetManager.dispose();
    }

    public boolean update() {
        return mAssetManager.update();
    }
}

Just create a new instance of Assets, call mAssets.load(), wait untile mAssets.update() becomes true and finally mAssets.createAssets();
On Android and iOS same code works fine.

I can confirm that stuff explodes when shadow is set to something.

[intrigus]

That's great to know that stuff explodes when shadows are used.
I'll look into it some time.

[piotr-j]

Not very useful, I'm aware. Sadly the exception seems to occur in the freetype.js code which makes it hard to debug.

@piotr-j do you by chance have a runnable and web accessible gwt version?
Or could you provide a more debug friendly stacktrace?
(I currently haven't setup libgdx or gwt^^)

[piotr-j]

Ill make one today. Is there more readable freetype.js somewhere?

Let me know if there is anything else I can do to make this easier

[intrigus]

Please try the new version "1.9.10.1" when it has reached maven central.
That may take up to one day.

Using your test it works.
@fgnm please confirm that it also works for you.

[piotr-j]

1.9.10.1 works, fantastic! How did you figure it out? Seems the cast was one of the issues, but i didnt get reasonable stacktraces for this...

[intrigus]

I told eclipse to compile gwt using -style PRETTY.
That produced readable enough stacktraces.
As soon as I saw the code the problem was clear :)

Closing as fixed.
