  Intro :
  This script allow you to play animation on map sprite, loop it, and follow
  the character
  
  -----------------------------------------------------------------------------
  How to use :
  Put this script below material and above main
  Use these script call in SET MOVE ROUTE (pick one u need)
  
  animloop(id)
  animloop(id, mirror)
  animloop(id, mirror, rate)
  animloop(id, mirror, rate, bottom)
  
  id      > animation id in database
  mirror  > will animation will be mirrored? (true/false)
  rate    > animation speed. Put in from range 1 ~ 4
  bottom  > true/false. If set to true, will play behind the sprite. Default
            is false
  
  If you just want to play animation on the back, just have to fill ALL the
  others even though u don't need it. For example
  
  animloop(66, false, 3, true)
            
  To stop animation, write a script call
  end_animloop

  Terms of use :
  Credit me, TheoAllen. You are free to edit this script by your own. As long
  as you don't claim it yours. For commercial purpose, don't forget to give me
  a free copy of the game.
