#  Animated Parallax#  Version 1.0#  Author: modern algebra (rmrk.net)#  Date: September 27, 2008
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Instructions:#   
#    The script operates by having multiple parallax backgrounds and switching#  between them at the interval set by $game_map.parallax_animation_frames
#    Thus, if you want to use an animated parallax, you need to do a few things:
#      (a) Make or find the parallax backgrounds you want to use and import
#        them into your game. Then, label them all the same with the one
#        distinction that at the end of each should have a _1, _2, etc...
#          Example Naming:
#            BlueSky_1, BlueSky_2, BlueSky_3, etc...
#      (b) Set the parallax background to any given map that you want the
#        animated parallaxes for. Be sure to set it to the first one you want
#        in succession, so BlueSky_1, not BlueSky_2 or _3. If you do set it to
#        BlueSky_2, then it will only animate between images _2 and _3.
#      (c) Scroll down to Line 36 and follow the instructions for setting
#        the animation speed

#  Basically, this method determines how many frames there are between   
# switching parallaxes. So, if you set it to 20, then it will switch   
# to next parallax in the animation every 20 frames.   
#      To do this, place this code below:   
#    when map_ID then frame_num   
#  So:   
#    when 1 then 20   
#  means that on Map 1, the parallax will switch to the next one   
#  every 20 frames. There are 60 frames in a second.   
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++   
# For Map 1   
when 1 then 20   
# For Map 2   
when 2 then 40   
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++   
#      END EDITABLE REGION   
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++    else     
# Default if Map not set and the parallax is animated      30    end    return frames  endend
