Play Field Imaging with Patterns

Pattern API

Using PFDrawLines.from_combo you can directly render lines in combinations.

It's recommended to use the recipe below and modify to your liking. The implementation is complex but easily modifiable.

from reamber.algorithms.pattern.Pattern import Pattern from reamber.algorithms.pattern.combos import PtnCombo from reamber.algorithms.playField import PlayField from reamber.algorithms.playField.parts import * from reamber.osu.OsuMap import OsuMap osu = OsuMap.read_file("path/to/map.osu") ptn = Pattern.from_note_lists([osu.notes.hits, osu.notes.holds]) grp = ptn.group(h_window=None, v_window=50, avoid_jack=True) keys = osu.stack().column.max() + 1 pf = ( PlayField(m=osu, duration_per_px=5) + PFDrawLines.from_combo(keys=keys, **PFDrawLines.Colors.RED, combo=PtnCombo(grp).template_chord_stream( primary=3, secondary=2, keys=keys, and_lower=True) ) + PFDrawLines.from_combo(keys=keys, **PFDrawLines.Colors.BLUE, combo=PtnCombo(grp).template_chord_stream( primary=2, secondary=1, keys=keys, and_lower=True) ) + PFDrawLines.from_combo(keys=keys, **PFDrawLines.Colors.PURPLE, combo=PtnCombo(grp).template_jacks( minimum_length=2, keys=keys) ) ) pf.export_fold(maxHeight=1750, stageLineWidth=0).save("osu.png")

Understanding the Recipe

We firstly group by hits and holds of the read osu map with a Vertical Window of 50.

ptn.group(h_window=None, v_window=50, avoid_jack=True)

Using that group, we construct lines for Chordstreams. The first chordstream template looks for all pairs that are [3, 2], [2, 3], [2, 2], [2, 1], [1, 2], [1, 1]

PFDrawLines.from_combo(
    ...,
    combo=PtnCombo(grp).template_chord_stream(primary=3,
                                              secondary=2,
                                              keys=keys,
                                              andLower=True))

The second one looks for all pairs that are [2, 1], [1, 2], [1, 1]

PFDrawLines.from_combo(
    ...,
    combo=PtnCombo(grp).template_chord_stream(primary=2,
                                              secondary=1,
                                              keys=keys,
                                              andLower=True))

The third locates jacks that are at least a minimum length of 2 (i.e. all jacks)

PFDrawLines.from_combo(..., combo=PtnCombo(grp).template_jacks(minimumLength=2,
                                                               keys=keys))

The last line folds the image so that it's more squarey then saves as osu.png

pf.export_fold(maxHeight=1750, stageLineWidth=0).save("osu.png")
