Preload

--Library created by RickG00 and WD200019

--  WARNING: this library requires the version of CYF 0.6.3 or higher, lower versions or Unitale won't work.

--  How to use:
--      1)Put this file into the "Libraries" folder of your mod;
--      2)In the encounter script, write " require "Libraries/Preload" " in the "EncounterStarting" function;
--      3)Profit??

--  Mods with tons of sprites, musics and sounds might take a while to start, but they will be lag-free when those files are used later.
