Module types

Core type definitions for RPE chart structures.

All chart data is stored and serialized as RpeJson. The primary sub-structures are:

• RpeJson — the root chart object
• JudgeLine — an animated line that spawns notes
• Note — a tap, hold, flick, or drag note
• Event / SpeedEvent — keyframe animation entries
• EventLayer — one layer of animation channels per line
• Bpm — a BPM change entry
• RpeMeta — song/chart metadata

Beat format

All time positions use the Beat tuple [measure, numerator, denominator], which represents the rational number measure + numerator/denominator. For example, beat 2.5 is [2, 1, 2].
