Jeffrey Han b54886a379 Follow-up to #126 .

- Fix the XDG directory flag that got removed with JarSplice. To enable XDG directories, set the 'Use-XDG' property in either build file to 'true'.
- Always re-build jars in the Gradle script (disable "up to date" for the task).
- Delete JarSplicePlus.jar since it's no longer being used.

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

opsu! runs on Windows, OS X, and Linux platforms. A libGDX port additionally supports Android devices.

Getting Started

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

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 both a Maven and Gradle project.

Maven

Maven builds are built to the target directory.

To run the project, execute the Maven goal compile.
To create a single executable JAR file, execute the Maven goal package -Djar. This will compile a jar to target/opsu-${version}.jar with the libraries, resources and natives packed inside the jar.

Gradle

Gradle builds are built to the build directory.

To run the project, execute the Gradle task run.
To create a single executable JAR file, execute the Gradle task build. This will compile a jar to build/libs/opsu-${version}.jar with the libraries, resources and natives packed inside the jar.
