Moveset
Movesets are defined on a per-character basis in a custom scripting engine developed by Arc System Works. These scripts are called BBScript, but are often abbreviated to BBS.
BBS is a very well-documented and understood format, allowing us to not just alter characters, but create entirely new ones as well.
We highly recommend you read A Sketch of the Arc System Works Engine Script, by Pangaea, first.
For the sake of consistency, all example code uses internal ArcSys nomenclature. Game-specific code might be included where deemed necessary.
