modifier

ModifierSelector is a panel that lets the player configure gameplay modifiers before starting a song. It appears on the song_select screen when the player selects the Modifier tile in the difficulty selector.

The five modifiers cycle through values with left/right input:

Modifier	Options
Auto	Off / On
Speed	0.5× – 4.0× (0.1 steps)
Display	Normal / Hidden
Inverse	Off / On (swaps left and right notes)
Random	Off / Kimagure / Detarame

ModifierSelector

ModifierSelector(PlayerNum player_num);

Loads the player's current modifier settings from persistent data, initialises current_mod_index to the first modifier, and creates all text objects for each option value.

Members

Member	Type	Description
is_finished	bool	true once the exit animation has completed

move	MoveAnimation*	Panel slide-in / slide-out animation, driven externally by SongSelectPlayer

Methods
