Jeffrey Han b0c0b44ef1 Major track length-related updates. - Parse and store the end time for every beatmap (i.e. end time of last hit object). - Added a 'length' sorting tab. - Added 'length' search condition. - Removed 'getTrackLength()' and 'getTrackLengthString()' methods, as they are no longer needed. - Added a loader spritesheet animation to render during MP3 conversions (in place of track length rendering upon completion). Other changes: - Added a yellow progress circle during lead-in time. - Fixed sorting tab positioning. - Slightly increased button animation speed in "Main Menu Exit" state.

README.md

opsu!

opsu! is an unofficial open-source client for osu!, a rhythm game based on popular commercial games such as Ouendan and Elite Beat Agents.

opsu! is written in Java using Slick2D and LWJGL, wrappers around the OpenGL and OpenAL libraries.

Getting Started

Java Setup

The Java Runtime Environment (JRE) must be installed in order to run opsu!. The download page can be found here.

Beatmaps

opsu! also requires beatmaps to run, which are available for download on the osu! website and mirror sites such as osu!Mirror or Bloodcat.

If osu! is already installed, this application will attempt to load songs directly from the osu! program folder. Otherwise, place songs in the generated Songs folder or set the BeatmapDirectory value in the generated configuration file to the path of the root song directory.

Note that beatmaps are typically delivered as OSZ files. These can be extracted with any ZIP tool, and opsu! will automatically extract them into the songs folder if placed in the SongPacks directory.

First Run

The Music Offset value will likely need to be adjusted when playing for the first time, or whenever hit objects are out of sync with the music. This and other game options can be accessed by clicking the wrench icon in the song menu.

Building

The LWJGL native libraries must be linked and distributed with this application. JarSplice is included in the tools directory to merge the files into a single executable fat jar for distribution.
