将TTF字体加载到AssetManager时出现异常

https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/extensions/FreeTypeFontLoaderTest.java

使用不同的参数和文件名将一个ttf文件放入AssetManager .

public class LoadingScreen implements Screen {

    private final GdxAsternets game;

    private float progress;

    public LoadingScreen(final GdxAsternets game){
        this.game = game;

        game.bitmapFont = new BitmapFont(Gdx.files.internal("font/myFont.fnt"));

        queueAssets();
    }

    @Override
    public void show() {
        progress = 0f;
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(0, 0, 0, 0);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        update(delta);
    }

    private void update(float delta){
        progress = MathUtils.lerp(progress, game.assetManager.getProgress(), 0.1f);
        if(game.assetManager.update() && progress >= game.assetManager.getProgress()- 0.1f){
            game.setScreen(game.menuScreen);
        }
    }

    private void queueAssets(){
        //Fontloader/Filehandler
        FileHandleResolver resolver = new InternalFileHandleResolver();
        game.assetManager.setLoader(FreeTypeFontGenerator.class, new FreeTypeFontGeneratorLoader(resolver));
        game.assetManager.setLoader(BitmapFont.class, ".ttf", new FreetypeFontLoader(resolver));

        //load timer font
        FreetypeFontLoader.FreeTypeFontLoaderParameter smallFontParams = new FreetypeFontLoader.FreeTypeFontLoaderParameter();
        smallFontParams.fontFileName = "font/Montserrat-SemiBold.ttf";
        smallFontParams.fontParameters.size = 40;
        game.assetManager.load("smallFont.ttf", BitmapFont.class, smallFontParams);

        //load game msg font
        FreetypeFontLoader.FreeTypeFontLoaderParameter bigFontParams = new FreetypeFontLoader.FreeTypeFontLoaderParameter();
        smallFontParams.fontFileName = "font/Montserrat-SemiBold.ttf";
        smallFontParams.fontParameters.size = 85;
        game.assetManager.load("bigFont.ttf", BitmapFont.class, bigFontParams);
    }
    /**Overring methods...*/
}

查看方法 . 引用我上面的链接: “字体名称是任意的,不指向文件盘” 我利用了

game.assetManager.load("font/Montserrat-SemiBold.ttf", BitmapFont.class, smallFontParams);

game.assetManager.load("smallFont.ttf", BitmapFont.class, smallFontParams);

一 更新(浮点增量)方法引发异常。资产管理人。正在调用update() .

例外情况:
