        public static void drawFont3D​(BitmapFont font,
                                      ExtSpriteBatch batch,

                                      boolean faceCamera)
        Draws the given text using the given font in the given 3D position using the 3D coordinate space. If faceCamera is true, the text is rendered always facing the camera. It assumes that ExtSpriteBatch.begin() has been called. This enables 3D techniques such as z-buffering to be applied to the text textures.
        Parameters:
        font - The font.
        batch - The sprite batch to use.
        text - The text to write.
        position - The 3D position.
        camera - The camera.
