• New system for detecting when the player is outdoors, indoors, or deep indoors
• A new soundpack making use of the new features: Matmos 2020 "Zen"
• Update checking for sound packs which support it
• Versions are now also built for Forge
• Made large_scanner more responsive
• Many bug fixes and performance improvements

Changes for soundpack authors

• Finished implementing streamed sounds
• New scanner: scan_raycast scans the blocks near the hits of roughly uniformly distributed rays. Has a weighted version (raycast_w) which gives a smaller weight the further away the block is.
  Variables:
  • .spaciousness: Larger the more spacious the player's environment is
    (e.g. low in a cave, high in an expansive area)
  • .is_outdoors: boolean which is true if the player is outdoors
• New scanner: scan_air finds nearby skylit air blocks using a flood fill until a threshold is reached. Used internally for indoor detection. It exposes the .is_near_surface boolean variable
• scan_large and scan_raycast have _above and _below versions which only count blocks above and below the player, respectively
• w_general has 4 new fields: can_snow_here, biome_is_snowy, biome_temperature, biome_rainfall
• Additions to json format (see the mat_zen soundpack for examples):
  • New built-in sets: _OUTDOORS, _INDOORS and _DEEP_INDOORS
  • A machine can have multiple streams which will all be played when the machine is active (stream can be a list)
  • Machines can be dual machines (using stream_pair and event_pair), which is a shorthand for having an indoors and and outdoors variation of the machine
  • Prefixing a set with ! in a machine means its negated version
• mat_pack.json:
  • Required MAtmos version can be specified (engineversion)
  • updatejson URL can be specified (uniquename and version must also be specified)
• expansions.json:
  • Global volume for the expansion can be set through the volumemodifier property
