Interface MinecraftDayTime

public interface MinecraftDayTime
Represents an in-game time of day.

  • Method Details

    • minecraftEpoch

      static MinecraftDayTime minecraftEpoch()
      A MinecraftDayTime that represents the Minecraft Epoch, which is 6:00am on Day 1.
      Returns:
      The MinecraftDayTime

    • ofInGameDuration

      static MinecraftDayTime ofInGameDuration(Engine engine, Duration duration)
      Creates a MinecraftDayTime based on the in-game time since the Minecraft epoch (6:00am on Day 1) for the given Engine.

      For example, if the supplied Duration was 1 day, 3 hours and 40 minutes, this would correspond to an in game time of 9:40am on Day 2.

      In the case where the supplied Duration does not completely align with a valid MinecraftDayTime, the nearest valid time will be returned.

      Parameters:
      engine - The Engine to use in calculating the day time
      duration - The duration since the Minecraft Epoch.
      Returns:
      The MinecraftDayTime
      Throws:
      IllegalArgumentException - if the duration is negative

    • ofWallClockDuration

      static MinecraftDayTime ofWallClockDuration(Engine engine, Duration duration)
      Creates a MinecraftDayTime that represents the world time if the world has been running for the supplied Duration in real world time under idealised conditions for the given Engine.

      For example, if the supplied Duration was 1 day, 3 hours and 40 minutes and each Minecraft day lasts 20 minutes in the vanilla game, this would correspond to 6:00am on day 84 (1 day, 3 hours and 40 minutes is 1660 minutes, which is 83 20-minute chunks).

      In the case where the supplied Duration does not completely align with a valid MinecraftDayTime, the nearest valid time will be returned.

      Parameters:
      engine - The Engine to use in calculating the day time
      duration - The wall-clock duration
      Returns:
      The MinecraftDayTime
      Throws:
      IllegalArgumentException - if the duration is negative

      The parameters are subject to the following constraints:

      • day must be positive;
      • hours is in 24-hour time, and so must be between 0 and 23, except on day 1, where it must be between 6 and 23; and
      • minutes must be between 0 and 59.

      In the case where the supplied time does not completely align with a valid MinecraftDayTime, the nearest valid time will be returned.

      Parameters:
      day - The day to set. Must be positive.
      hours - The hour to set in 24 hour time.
      minutes - The minute to set.

    • of

      static MinecraftDayTime of(Engine engine, Ticks ticks)
      Creates a MinecraftDayTime based on the number of Ticks elapsed since the Minecraft epoch (6:00am on Day 1) for the given Engine.

      For example, if the supplied Ticks was Ticks.of(18000) on the vanilla server, this would correspond to an in game time of 12:00am on Day 2 (18 hours after Minecraft epoch).

      Parameters:
      engine - The Engine to calculate the time for.
      ticks - The Ticks since the Minecraft Epoch.
