EZvac

Prerelease. The fifth pilot of the 2.0 realism update. The save format is the same as the earlier pilots (format 6), so it's a drop-in upgrade. See the Pilot 1 notes for everything 2.0 adds.

Weather sensors

A birch button is now a fourth kind of sensor:

/hvac create sensor [label]

• It shows Clear, Rain, Thunder or Snow on sensor hubs and in chat.
• Like a rain gauge, it needs open sky. Under a roof, glass or leaves it shows Covered.

Readings vary from spot to spot

A house is no longer one number from wall to wall. Readings differ a little from place to place:

• Humidity follows, so a warmer spot reads a little drier.
• Changes are gradual: they build over a few blocks, and each spot drifts slowly over a few in-game hours.
• Only readings vary: thermometers, sensors, the HUD, /hvac temperature and placeholders. Thermostats and their signs keep the room's own value, so systems never chase it.
• Tuning is in the new variance: section.

Fixed

• Standalone dehumidifiers and humidifiers in one space disagreed. One shed read 54% on one sign and 79% on the other. Units that share air now share one humidity and work on it together, and the water dehumidifiers remove is split between their tanks.
• Long sign lines were cut by the game. EZvac | Dehumidifier showed as EZvac |.
  • Lines are now measured in pixels, the way the game draws them.
  • A header drops EZvac | when the label needs the room.
  • A reading that doesn't fit is left off whole, never cut in half.
  • Hanging signs, which are narrower, work too.

Added

• "Air too cold." A dehumidifier in air too dry for its coil shows Air too cold instead of Running. Its coil works down to a 35 °F dew point, so this happens in snowy biomes. It can't dry that air, the same as a real one, and /hvac info explains why.

• Configurable sounds. Every sound EZvac plays is a "sound volume pitch" line under audio.sounds:

  audio:
    sounds:
      equipment-hum: ["block.beacon.ambient 1.6 0.55"]
      vent-airflow: ["block.conduit.ambient 0.3 0.5"]
  

  • [] silences an event, and resource-pack sounds work too.
  • Pick mono sounds: stereo ones sound the same at any distance.
  • The defaults are the sounds EZvac already played.

• Vent airflow sound. While a system runs, air vents near a player softly play the conduit's hum, at most one per cluster of vents. Pools and water vents stay quiet.

Upgrading

Stop the server, replace the EZvac jar with EzVac-ALPHA-2.0-P5.jar, and start it again. Nothing needs converting.

• New config sections: audio.sounds and variance: are added to your config.yml on startup. Nothing you already have changes, and the old file is kept as config.yml.before-ALPHA-2.0-P5.bak.
• Hum settings: if you tuned audio.hum-volume or audio.hum-pitch, your hum carries over into the new sound lines. Those two settings are no longer read.
• No going back with weather sensors: Pilot 4 can't read a world that has weather sensors in it. As always, downgrading isn't supported.
• Pilot 2 correction: that release raised the default dehumidifier range to 30, but a config.yml written by Pilot 1 keeps range: 12 until you change it.

Verified

• Tests: 212 automated tests.
• Live, on Purpur 1.21.1:
  • Config upgrade: a Pilot 4 config.yml was brought up to date with a backup.
  • Shared humidity: a dehumidifier and a humidifier in one shed read the same 89%.
  • Signs: a dehumidifier sign showed Dehumidifier, and a hanging sign fit without cutting a reading.
  • "Air too cold": a snowy-taiga dehumidifier showed it.
  • Weather sensors: a weather hub went Clear → Rain → Thunder while a roofed sensor stayed Covered.
  • Variance: an AC room read 70.3–70.6 °F while its thermostat kept 70.1 °F; outdoors read 61.9–64.4 °F.
  • Vent sound: running AC vents played the airflow sound and stopped when the system was switched off, and a pool stayed silent.
• In-game: tried before release.
