Background Scripting

Background Scripting is the general ideal of using BGAnimations and RandomMovies to "script" songs, giving them something nice to display while the game goes on. a good example of these would be DDR 3rd Mix, using BGAnimations, and DDR Extreme and In The Groove, both using RandomMovies.

These can be either handled by using StepMania 3.0's version of BGAnimation, or 3.9 and above's support for BGAnimation scripting. Collections of movies that provide the background with a file to animate in the background. These are usually paired with transitions or live effects.
