It's pretty easy to do, go to the Party Script(UI_Party if using v19+)
And find the line:
addBackgroundPlane(@sprites,"partybg","Party/bg",@viewport) and replace it with the next lines:
Code:
@sprites["partybg"]=AnimatedPlane.new(@viewport)
@sprites["partybg"].bitmap=RPG::Cache.picture("Party/bg")
Next, find
pbUpdateSpriteHash(@sprites), and paste this below it.
Code:
if @sprites["partybg"]
@sprites["partybg"].ox+=1
@sprites["partybg"].oy+=1
end
To change the speed of the animation, edit the 1 at @sprites["partybg"].ox+=1 or @sprites["partybg"].oy+=1.
