score_history

The ScoreHistory class displays the player's saved score for the currently selected song in the song-select screen. When scores exist for multiple difficulties it cycles through them automatically, showing each one for one second. Owned by box_song.

Construction

ScoreHistory(const array<optional<Score>, 5>& scores, double current_ms);

Parameter	Description
scores	Array of five optional Score values, one per difficulty slot (Easy through Ura)
current_ms	Current song-select timestamp, used as the starting reference for the one-second timer

Filters out empty slots and populates available with only the difficulties that have a recorded score. curr_index starts at 1 % available.size() so the first score shown on the next cycle is not the same as the initial one.

Members

Member	Type	Description
available	vector<DiffScore>	Scores that actually exist, each paired with their difficulty index
curr_index	int	Index into available for the currently displayed entry
last_ms	double	Timestamp of the last cycle step

DiffScore

Private helper struct.

Field	Type	Description
diff	int	Difficulty index (0 = Easy, 4 = Ura)
score	Score	The saved score data for that difficulty

Methods

void update(double current_ms);

Does nothing if available is empty. Otherwise advances curr_index by one (wrapping) whenever at least 1000 ms has elapsed since last_ms, then updates last_ms.

void draw();

Does nothing if available is empty. Calls draw_long() to render the full score panel for the current entry.

Private methods

void draw_long();

Renders the full score panel using LEADERBOARD textures. Shows:

• Background and title strip.
• Score mode indicator (SHINUCHI or NORMAL) and PTS label with colour adjusted for the mode.
• Difficulty badge for curr_diff.
• Four row backgrounds for the judge lines.
• JUDGE_GOOD, JUDGE_OK, JUDGE_BAD, and JUDGE_DRUMROLL label textures.
• Score, good, ok, bad, and drumroll values as right-aligned digit strings using LEADERBOARD::COUNTER and LEADERBOARD::JUDGE_NUM textures.

void draw_short();

Renders a compact single-score panel (score only, no per-judge breakdown). Used when the panel area is too narrow for the full view. Currently not called by draw() but available for callers that need the short form.
