Since skin version 2.4, the osu!mania mode has been more and more customizable/skinable. Because of this, enabling skin versions 2.3 and below will not enable some features! Notably, skin versions 2.4+ has improved scaling and new commands for the skin.ini file.
osu!mania has a separate lighting image than osu!standard and osu!catch does.
While osu!standard and osu!catch uses a circular one for its hitobjects, osu!mania can use any shape to overlay the keys when they are being pressed against a note.
LightingL are animatable images that appear when you hit a note on judgment bar.
Do note that this can animated, though this is a pretty fast animation.
LightingN appears after a note is hit. Whereas,
LightingL appears after the hold note is pressed.
mania-hit300g are the hitbursts for osu!mania.
These are animatable when playing ingame, but their animations plays very quickly and is not looped, so try to be clever to make them visible.
When the player is viewing the ranking screen, do note that osu! will not animate the animations, if given. Instead, osu! will take the first frame and display that on the scoreboard.
mania-keyS are the keys/buttons.
Be careful when using patterns.
Because later in .ini files you might set length of buttons that can make patterns stretched.
The special button (
mania-keyS) is used in 7k/8k game mod.
mania-keySD are the same as above, but appears when pressed down.
mania-note1/2/S - Skin for mania notes. mania-note1H/2H/SH - Skin for head parts of "slider". mania-note1L/2L/SL - Skin for body (technically called the Length) part of "slider". This one can be animated. mania-note1T/2T/ST - Skin for end parts of "slider".
The osu!mania game mode is composed of a stage. The stage has several parts in it, listed below.
mania-stage-hint - known as judgment bar. Place where you need to hit note correctly. If you have problems with correct position of it use judgment line that you can set in .ini files.
mania-stage-left/right - A left/right part of mania playfield. They aren’t restricted by size, so you can make neat sides by adding something more than border. If you will use it just for border, do a smaller part - rest will be repeated from upper part of screen to bottom.
But if you are going to something larger, set height at 768px and width of your preference.
mania-stage-light - special light that appears on column stage when you hit a button. Game will always try to fit it into column width, making them wide will force game to resize it to size of column.
The osu!mania mode has a few mods of its own.
The key mods changes the number of keys you play up to. However, this does not affect osu!mania maps.
The CO-OP mod splits the stage in two, doubling the number of keys for osu!standard maps. This does work for osu!mania maps, but will only split the stage in two, distributing the keys evenly on both sides.
The random mod will randomly mix the columns around, making maps harder (or easier).
