mania)¶

parsecore converts osu! beatmaps to the other rulesets exactly like the game including the legacy osu!mania pattern generator with its osu!stable RNG.

from parsecore.Beatmap.beatmap import Beatmap as UserBeatmap
from parsecore.Performance import Beatmap, Difficulty, GameMode

user_map = UserBeatmap.from_path("path/to/osu_map.osu")

# Play an osu! map in another ruleset
bm = Beatmap.from_user_beatmap(user_map, override_mode=GameMode.MANIA)
attrs = Difficulty().calculate(bm)
print(attrs.stars, attrs.n_objects, attrs.n_hold_notes)

Key mods on mania converts¶

Mania key mods change the column count of a convert, and therefore its star rating and pp (7K is the legacy bit 1 << 18):

attrs = Difficulty().mods(1 << 18).calculate(bm)  # 7K

Note

Key mods only affect osu! → mania converts. On native mania maps they have no effect, which matches the game.
