  • Method Details

    • ceil

      public static int ceil​(float floatNumber)
      Round the given float to the next whole number
      Parameters:
      floatNumber - Float to round
      Returns:
      Rounded number

    • constrain

      public static double constrain​(double num, double min, double max)
      If number is greater than the max, set it to max, and if number is lower than low, set it to low.
      Parameters:
      num - number to calculate
      min - the lowest value the number can be
      max - the greatest value the number can be
      Returns:
      - min if num is lower than min
      - max if num is greater than max
      - num otherwise

    • constrain

      public static int constrain​(int num, int min, int max)
      If number is greater than the max, set it to max, and if number is lower than low, set it to low.
      Parameters:
      num - number to calculate
      min - the lowest value the number can be
      max - the greatest value the number can be
      Returns:
      - min if num is lower than min
      - max if num is greater than max
      - num otherwise

    • getNbtByte

      public static byte getNbtByte​(Object value)
      Ensures the resulting object is a byte. Java Edition does not care whether a byte is encoded as an integer or not; it converts it into a byte anyway.
      Parameters:
      value - The value to convert
      Returns:
      The converted byte

    • chunkPositionToLong

      public static long chunkPositionToLong​(int x, int z)
      Packs a chunk's X and Z coordinates into a single long.
      Parameters:
      x - the X coordinate
      z - the Z coordinate
      Returns:
      the packed coordinates

    • getGlobalPaletteForSize

      public static int getGlobalPaletteForSize​(int size)
      Returns:
      the bits per entry used when this number is the maximum amount of entries.
