  • Field Details

    • DEFAULT_EMBED_TEXTURES

      public static final boolean DEFAULT_EMBED_TEXTURES
      Indicates if textures must be embedded into resulting file.
      See Also:

    • DEFAULT_USE_REMOTE_TEXTURE_URL

      public static final boolean DEFAULT_USE_REMOTE_TEXTURE_URL
      Indicates if by default a URL indicating where the texture can be located should be included into resulting file.
      See Also:

    • DEFAULT_USE_REMOTE_TEXTURE_ID

      public static final boolean DEFAULT_USE_REMOTE_TEXTURE_ID
      Indicates if by default an identifier for the texture should be included into resulting file so that texture image can be fetched by some other mean.
      See Also:

    • charset

      private Charset charset
      Indicates charset to use in resulting JSON file. By default, this will be UTF-8.

    • writer

      private BufferedWriter writer
      Writer to write resulting JSON into output stream.

    • textureCounter

      private int textureCounter
      Counter for the number of textures that have been read.

    • embedTexturesEnabled

      private boolean embedTexturesEnabled
