Jeffrey Han 25a7a826f1 More graphical updates, some code cleanup, and minor fixes. - The MenuButton class now fully supports hover effects (scale, fade, rotate) for Animations. - Used a fixed location for the selection buttons in the song menu (previously based on the "back" button width, which varies widely in different skins). - Added hover effects for "retry" and "exit" buttons in the ranking screen. - Changed animation speed of back/skip buttons. - Fixed a bug where main menu showed the incorrect number of songs loaded during searches. - Removed unneeded draw() methods in Utils for color filters (since `69f5aa5`). - Moved Utils.drawCentered(Image, ...) into the Image class. - Added overwritten Image class to Maven excludes.

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

Precompiled binaries for opsu! can be found on the releases page, with the latest builds at the top.

Java Setup

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

Beatmaps

opsu! requires beatmaps to run, which are available for download on the osu! website and mirror sites such as osu!Mirror or Bloodcat. Beatmaps can also be downloaded directly through opsu! in the downloads menu.

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 "Other Options" button in the song menu.

Building

opsu! is distributed as a Maven project.

To run the project, execute the Maven goal compile exec:exec.
To create a single executable JAR file, execute the Maven goal install -Djar. This will link the LWJGL native libraries using a modified version of JarSplice, which is included in the tools directory in both its original and modified forms. The resulting file will be located in target/opsu-${version}-runnable.jar.
