General[]

Font
  • Added unihex glyph provider.
    • A new glyph provider for reading Unifont HEX files.
      • HEX format describes bitmap font glyphs.
        • Height of every glyph is 16 pixels.
        • Width of glyph can be 8, 16, 24 or 32 pixels.
      • Every line is made of two hexadecimal numbers separated by :.
      • First value describes codepoint - it must have 4, 5 or 6 hex digits.
      • Second value describes glyph as a stream of bits, line by line.
    • When rendering, empty columns on left and right side of glyph are removed.
      • Custom glyph widths can be set with size_overrides.
    • Provider requires two fields:
      • hex_file: Path to ZIP archive containing one or more *.hex files (files in archive with different extensions are ignored).
      • size_overrides: List of codepoint ranges that should have width different that auto-detected (based on empty space in glyph). Fields:
        • from, to: Start and end of codepoint range (inclusive).
        • left, right: Integers describing position of left-most and right-most columns of glyph in range.
          • Any bits in columns outside this range will be discarded.
  • Added reference glyph provider.
    • New glyph provider can be used to include providers from other fonts.
      • Providers are guaranteed to be loaded only once, no matter how many times they are included.
    • Provider has one field id, that describes other font to be included in currently loaded one.
      • Inclusion is performed after all fonts are loaded, so it will include all providers for a given font defined in all datapacks.
Loot tables
  • Added sniffer_digging: contains torchflower_seeds, and pitcher_pod.
    • Controls what can be found by sniffers when digging.
Music
