// Transcodes a SIF1/NPPS4 beatmap (array of {timing_sec, effect, effect_value, position})

// into the SIF2 chart JSON the client deserializes into NoteData.
|
|
//
|
|
// SIF1 note effects, from the game's own LiveModel.NoteEffect
|
|
// (m_live/model/note_effect.lua): note_normal 1, note_event 2, note_hold 3, note_bomb_1 4,
|
|
// note_bomb_3 5, note_bomb_5 6, note_bomb_9 7, note_slide 11, note_slide_event 12,
|
|
// note_slide_hold 13, with isHold(e) = e == 3 and isSlide(e) = e >= 11.
|
|
//
|
|
// SIF2 side: `type` only distinguishes an ordinary note (1) from a star/bomb note (3).
|
|
// LiveTimeController.ToMarkerType accepts 1..3 and maps anything else to None; type 2 exists in
|
|
// the enum but appears in ZERO of the 2146 shipped charts, so nothing emits it here.
|
|
//
|
|
// A SLIDE is structural, not a type. MarkerData derives it from the parent/child chain:
|
|
// IsSliderMarker chained and the child is on a DIFFERENT line -> a slide segment
|
|
// IsSliderLongMarker chained, child SAME line, parent different -> a slide ending in a hold
|
|
// IsDistanceMarker has both a parent and a child -> a middle segment
|
|
// So a hold is a chain that stays in its lane and a slide is a chain that moves across lanes;
|
|
// both are type 1. This is also how the client counts combo (NoteData.CalcMaxCombo: a note whose
|
|
// child shares its line does not count, its tail does).
|
|
//
|
|
// Mapping rules:
|
|
// - line = position - 1 (both are right-to-left)
|
|
// - effect 1 (note_normal) and 2 (note_event) -> type 1 (tap). note_event is an ordinary
|
|
// note that also fed SIF1's event scoring; it plays identically and SIF2 has no
|
|
// equivalent, so the distinction is dropped. Simultaneous hits are expressed by sharing
|
|
// a spawn num, not by the effect.
|
|
// - effect 3 (hold) -> head note (type 1) at timing_sec plus a SYNTHESIZED tail note
|
|
// (type 1, same line) at timing_sec + effect_value, linked through parent/child ids
|
|
// - effect 4/5/6/7 (bomb_1/3/5/9, SIF1's star notes) -> type 3, SIF2's bomb note. SIF1
|
|
// varies the blast width per effect; SIF2 has one bomb with one damage value, so the
|
|
// four collapse into type 3 and only the radius is lost. Previously only bomb_1 mapped
|
|
// here and the three wider ones arrived as ordinary taps.
|
|
// - effect 11/12/13 (slide) -> CHAINED across lanes, all type 1. Slides sharing a notes_level
|
|
// form one run: sorted by time and linked parent -> child, so each link crosses lanes and
|
|
// the client sees a slider. A run ends on effect 13 (slide hold), whose synthesized
|
|
// same-line tail then makes it IsSliderLongMarker — the slide settling into a hold the
|
|
// player releases. Verified against a real upload: every notes_level shared by more than
|
|
// one note held exactly the slide-effect notes, each a monotonic sweep like
|
|
// pos 9->8->7->6 with effects 11,11,11,13.
|
|
// A lone slide with no chain partner stays a plain tap: a slider needs a cross-lane child.
|
|
// - effect 0 (random) and anything else unknown -> plain type 1. Every effect the game
|
|
// actually defines is covered above, so this is only a floor for hand-authored charts.
|
|
// - notes_attribute is dropped (SIF2 has no per-note attribute). notes_level is consumed as
|
|
// the chain id above and not emitted; force_sync_group_id stays 0.
|
|
// - ids are sequential from 1 in time order. num is the spawn group: the dummy
|
|
// header occupies 100, real groups count up from 101, and notes that hit
|
|
// simultaneously (equal timing_sec, which covers SIF1 effect 2 pairs) share one num.
|
|
// - notes[0] is ALWAYS the dummy header (id 0, num 100, type 0) - the client
|
|
// deserializes it verbatim.
|
|
// - max_combo_count = all real notes EXCEPT hold heads whose tail is on the same
|
|
// line (the game counts a same-lane hold as one combo for the chain)
