NAME
Games::EternalLands::Binary::Unitvec16 - 16-bit quantized unit vectors as used by Eternal Lands
SYNOPSIS
use Games::EternalLands::Binary::Unitvec16 qw(pack_unitvec16 unpack_unitvec16);
# Pack to an unsigned short (i.e. a 16-bit unsigned number)
$short = pack_unitvec16([1, 0, 0]);
# Unpack from an unsigned short
$vector = unpack_unitvec16($short);
...ABSTRACT
This module provides functions to pack and unpack 16-bit quantized unit vectors as used in certain game data files by Eternal Lands.
FUNCTIONS
pack_unitvec16
Takes a reference to an array of length 3 and returns a packed 16-bit integer.
unpack_unitvec16
Takes a 16-bit integer and returns a reference to an array with 3 floating-point elements in it.
NOTE
Be sure to use the correct byte order if you are reading the 16-bit integers from a file or network packets. For Eternal Lands data, this will almost certainly be in little-endian byte order. So if your machine is not little-endian, remember to convert the data appropriately (see pack).
