    • applyToDye

      public static double[] applyToDye(double[] currentDye, double[] dyeToApply, float factor)
      Subtracts a dye to another dye. It does this by subtracting the multiplied value of the other color planes from a plane.
      Parameters:
      currentDye - The dye to subtract the dyeToApply from. (3-element array with 0-1 values).
      dyeToApply - The dye that will be subtracted from currentDye (3-element array 0-1 values).
      factor - A float which will be multiplied by each color plane's end result. Used to apply intensity on an individual basis.
      Returns:
      The resulting dye (3-element double array).

    • applyDye

      public static Color applyDye(Color color, double[] dye)
      Applies a dye to a color by multiplying each color plane with their dye counterparts.
      Parameters:
      color - The color to apply the dye to.
      dye - The dye that will be multiplied with the color (3-element array).
      Returns:
      The resulting color.

    • getColorFromImage

      public static Color getColorFromImage(BufferedImage bi)
      Calculates the average color from an image. Inspired by: https://stackoverflow.com/questions/28162488/get-average-color-on-bufferedimage-and-bufferedimage-portion-as-fast-as-possible.
      Parameters:
      bi - The image that the color will be sampled from.
      Returns:
      The average color of the image.

    • colorFromType

      public static Color colorFromType(org.bukkit.block.Block block, double[] dye)
      Gets the color for a block and applies a dye to it.
      Parameters:
      block - The block to get the color for.
      dye - The dye to apply to the color for the block (3-element array).
      Returns:
      The ready-to-use color from the block with the dye applied.

    • isWithinBlockIgnoreY

      public static boolean isWithinBlockIgnoreY(org.bukkit.Location loc1, org.bukkit.Location loc2)
      Checks if the two locations are inside the same block, ignoring the Y-axis.
      Parameters:
      loc1 - The location to check against loc2.
      loc2 - The location to check against loc1.
      Returns:
      A boolean that only is true when the locations are both in the same X and Z value.

    • positiveYaw

      public static float positiveYaw(float rawYaw)
      Returns a yaw that is always a positive number. The returned value will resemble a 360-degree output.
      Parameters:
      rawYaw - The yaw gotten from spigot (-180 to 180)
      Returns:
      The transformed yaw (0 to 360).

    • difference

      public static double difference(double val1, double val2)
      Returns the difference between two numbers regardless of one or the other being negative.
      Parameters:
      val1 - The first value.
      val2 - The second value.
      Returns:
      The difference between the two values.
