'''''StepMania''''' is a [[cross-platform]] [[Rhythm game|rhythm video game]] and [[game engine|engine]]. It was originally developed as a clone of [[Konami]]'s [[arcade game]] series ''[[Dance Dance Revolution]]'', and has since evolved into an extensible rhythm game engine capable of supporting a variety of rhythm-based game types. Released under the [[MIT License]], ''StepMania'' is [[open-source software|open-source]] [[free software]].<ref>{{Cite news |url=http://news.spong.com/article/12240/Rock_Bands_Guitar_Heroes_Recriminations_and_Comedy_Litigation?cb=767 |title=Rock Bands, Guitar Heroes, Recriminations and Comedy Litigation |date=2007-04-04 |work=Sprong |access-date=2008-11-02}}</ref>

Several video game series use ''StepMania'' as their game engines. This includes [[In the Groove (series)|''In the Groove'']], ''[[Pump It Up Pro]]'', ''Pump It Up Infinity'', and ''[[StepManiaX]]''. ''StepMania'' was included in a video game exhibition at New York's [[American Museum of the Moving Image|Museum of the Moving Image]] in 2005.<ref>{{Cite web |url=http://www.movingimage.us/site/screenings/content/2005/digital_play_reloaded.html |title=Museum of the Moving Image article |access-date=2006-12-26 |archive-date=2007-01-02 |archive-url=https://web.archive.org/web/20070102151009/http://www.movingimage.us/site/screenings/content/2005/digital_play_reloaded.html |url-status=dead }}</ref><ref>{{Cite web|url=http://www.movingimage.us/site/screenings/content/2005/digital_play_reloaded.html |title=Museum of the Moving Image |date=2005-10-24 |access-date=2017-05-11 |url-status=bot: unknown |archive-url=https://web.archive.org/web/20051024022925/http://www.movingimage.us/site/screenings/content/2005/digital_play_reloaded.html |archive-date=2005-10-24 }}</ref>

==Development==
''StepMania'' was originally developed as an open-source clone of [[Konami]]'s [[arcade game]] series ''[[Dance Dance Revolution]]'' (DDR). During the first three major versions, the Interface was based heavily on DDR's. New versions were released relatively quickly at first, culminating in version 3.9 in 2005. In 2010, after almost 5 years of work without a stable release, ''StepMania'' creator Chris Danford forked a 2006 build of ''StepMania'',<ref name="Danford08-10">{{cite web|last=Danford|first=Chris|title=StepMania project reboot: opinions wanted|url=http://www.stepmania.com/forums/showthread.php?t=24111|work=StepMania.com|access-date=15 August 2010|url-status=dead|archive-url=https://web.archive.org/web/20110222071621/http://www.stepmania.com/forums/showthread.php?t=24111|archive-date=22 February 2011}}</ref> paused development on the [[bleeding edge]] branch, and labeled the new branch ''StepMania'' 4 beta. A separate development team called the Spinal Shark Collective [[Fork (software development)|fork]]ed the bleeding-edge branch and continued work on it, branding it sm-ssc. On 30 May 2011, sm-ssc gained official status and was renamed ''StepMania'' 5.0. Development on the upcoming version, 5.1, has gone cold over the past few years after a couple of betas were released over at GitHub.<ref>{{Cite web|url=https://github.com/stepmania/stepmania/releases|title = Releases · stepmania/Stepmania|website = [[GitHub]]}}</ref> ''[[Project OutFox]]'' (formerly known as ''StepMania'' 5.3, initially labeled as ''FoxMania'') is a currently closed-source fork of the 5.0 and 5.1 codebase originally planned to reintegrate in StepMania, however further in development, it was decided to become an independent project due to its larger scope of goals while still sharing codebase improvements to future versions of StepMania.<ref>{{Cite web|url=https://projectoutfox.com/news/new-community-policies|title = New community policies}}</ref> These improvements include modernizing the original codebase to improve performance and graphical fidelity, refurbishing aspects of the engine that have been neglected, and to improve and expand its support for other game types and styles.

==Gameplay==
The primary game type features the following game play: as arrows scroll upwards (or downwards if the player has selected the "Reverse" scroll modifier) on the [[Display device|screen]], they meet a normally stationary set of target arrows.  When they do, the player presses the corresponding arrows on their keyboard or [[dance mat]]. The moving arrows meet the targets based on the beat of the song. The game is scored based upon how accurately the player can trigger the arrows in time to the beat of the song. The player's efforts are given a letter [[Grading in education|grade]] and a number score that tell how well they have done. An award of AAA+ (triple A plus, formerly AAAA or quadruple A) is the highest possible award available on a standard installation and indicates that a player has triggered all arrows with "Flawless" timing (within 0.0225 seconds under official [[Computer configuration|settings]]) and avoided all mines and completed all hold (freeze) arrows. An E indicates failure for a player to survive the length of the song without completely draining their life gauge. Default scoring and grading for ''StepMania'' is similar to scoring in ''Dance Dance Revolution''; however, timing and scoring settings can easily be changed.

During a song, if the player successfully triggers all arrows with "great" or better timing, the player will receive the message "Full combo" alongside their grade. Players can also achieve "Full perfect combo" for completing a song with all arrows triggered with perfect timing or better, and a "Full flawless combo" if all arrows are triggered with "flawless" timing.

''StepMania'' allows for several input options. Specialized adapters that connect console peripherals like [[PS2]] and [[Xbox (console)|Xbox]] controllers or dance pads to one's computer can be used. Alternatively, the [[Keyboard (computing)|keyboard]] can be used to tap out the rhythms using arrow or other keys. Many song charts designed for keyboard are unable to be passed using a pad. In addition, the game possesses the capability to emulate other music games, such as ''[[Beatmania]]'' itself, o2Jam and [[DJMAX|''DJMax'']]'s 7-key arrangement, [[Pump It Up (video game)|''Pump It Up'']] and [[Techno Motion|''TechnoMotion'']] - scoring however, remains similar to old DDR-style play by default (i.e. more weight is given for later notes).

==Features==
*Custom Songs ("Stepfiles") also known as "Simfiles": StepMania allows users to create their own custom dance patterns to any song in [[.ogg]] or [[.mp3]] format. The program includes a comprehensive Step editor to aid the creation of these stepfiles. Many Simfile websites exist where users share and distributed Simfiles for songs. Additionally, official [[Dance Dance Revolution|DDR]] and [[In the Groove (video game)|''In The Groove'']] songs with their original steps are commonly available for StepMania.
*Background [[animation]]s: Support for many types of animations behind the arrows onscreen, including sprite-based animation sequences, a single full-motion video or multiple FMV visualization overlays but are disabled if the song contains exclusive video.
*Modifiers: Visual mods that affect the scroll of arrows and either increase or decrease difficulty. StepMania includes multiple modifiers featured in Dance Dance Revolution as well as dozens of additional modifiers created exclusively for StepMania, including custom SPEED options.
*Multiple arrow types:
** Mines ("Shock" arrows in [[Dance Dance Revolution X|''DDR X'']]): An object that scrolls onto the screen along with the arrows. If a player triggers the mines, they will be penalized by having their dance gauge reduced and, customizing a theme, breaks the current combo chain that the player had going. However, the mines in ''StepMania'' are different from the Shock Arrows in ''DDR X i''n that the latter also turns the notes invisible for a brief period of time and breaks the current combo chain that the player had going. This step type was developed for the ''StepMania''-based arcade game ''[[In the Groove (game)|In The Groove]]'', and was ported into ''StepMania'' itself during development of that title. There are several variations of these objects that effect scoring in different ways.
** Holds (also called Freeze Arrows): A long arrow that requires you to keep your feet or finger on the corresponding panel for its duration.
** Rolls: A special hold arrow which requires a rapid tap on to keep alive. This step type was developed for the sequel to ''In The Groove'', ''[[In the Groove 2]]''.
** Lift: a special type of arrow (colored Gray by default) which requires the key (or panel) to be held down '''before''' the note passes and released when the note passes the target arrows. This is different from freeze arrows in that the timing of the press is not important, only when the note is released.
* Multiple game types, including partial simulation of other rhythm games like ''Pump It Up'', ''[[ParaParaParadise]]'' and ''[[beatmania IIDX]]''.
* Real-time lyrics, which display on the opposite side of the screen for stepfiles that have [[LRC (file format)|accompanying lyric data]].
* Custom themes: users can create their own [[Skin (computing)|skins]] for ''StepMania''. Themes can vary from simple replacement of images to drastic changes that can be implemented by scripting its [[Lua (programming language)|Lua]] backend.
* Dancing characters: 2-dimensional and 3-dimensional character models that dance in the background according to a pre-defined routine.
* Infinite BPMs: an official implementation in ''StepMania'' 4 of a bug in the 3.9 series that could be exploited to create "warps" in stepcharts using negative speeds.
* Network play: support for lobby-based online play, dubbed ''StepMania Online.'' Typically, users connect through the ''StepMania Online''<ref>[https://www.stepmaniaonline.net StepMania Online official website]</ref> centralized server. Support for network play was added to the ''StepMania'' tree in 2005 and is available in all later builds. All players must have a copy of the song chosen by the host in order to play.

==Availability==

[[File:Stepmania-arcade.jpg|thumb|right|StepMania-based arcade machine in a Chinese amusement park]]

Some versions of ''StepMania'' will run on most common operating systems ([[Microsoft Windows]] [[Windows 98|98]]/[[Windows Me|Me]]/[[Windows 2000|2000]]/[[Windows XP|XP]]/[[Windows Vista|Vista]]/[[Windows 7|7]]/[[Windows 8|8]], [[Linux]], [[FreeBSD]], [[Mac OS X]]), as well as the [[Xbox]] console. It has also been used as the base engine in a variety of [[free software]] and [[proprietary software|proprietary]] products for various platforms.

===Use in products===
Several ''StepMania''-based commercial games have been released due to its open nature:

*''[[In the Groove (game)|In the Groove]]'' (ITG) is an arcade dance game series developed by the core ''StepMania'' developers, and is based on 3.9 and a CVS build of StepMania often known as version 3.95. To prevent [[Copyright infringement of software|unauthorized copying]], ''StepMania'' was re-licensed under a more permissive license (changed from [[GNU General Public License|GPL]] to the [[MIT License]] with the agreement of all coders, in exchange for their names appearing on the ITG credits screen), not requiring source code to be published on derivative works, and thus allowing ITG's [[copy control]] to remain proprietary and [[closed source software|closed source]].
*''[[Pump It Up Pro]]'' is a spinoff of the [[List of Pump it Up video games|''Pump it Up'']] series headed by former ITG developers and musicians. The game utilizes a build of StepMania 4 for its engine, which also led to improved Pump support in ''StepMania'' itself.
*''Pump It Up Infinity'' is another spinoff of the ''Pump it Up'' series aimed primarily at North American audiences. Unlike the Pro series, however, it is managed directly by [[Andamiro]]. The game is based on ''StepMania'' 5.
* ''[[StepManiaX]]'' is a spiritual successor to In The Groove, with the addition of the Center panel and other features.

==StepMix==
''StepMania'' developers conducted StepMix contest for step builders to create stepcharts/stepfiles that can be played using ''StepMania''. StepMix 1, 2, 3, and 4 were run successfully. Participants need to have a song to be used in the stepchart/stepfile. The song must be under a compatible license for distribution or be authorized for use in StepMix 4, or the entry is automatically disqualified.<ref>[http://www.stepmaniawiki.com/wiki/StepMix_4_Contest#Entry_requirements StepMix 4 Contest Entry requirements] {{webarchive|url=https://web.archive.org/web/20080819182452/http://www.stepmaniawiki.com/wiki/StepMix_4_Contest |date=2008-08-19 }}</ref> Additionally, if the graphics used in the entry are found to have been copied from another artist and used without their authorization (as happened once in StepMix 2<ref>[http://www.stepmania.com/boards/viewtopic.php?t=4063 My art is in a song...but I dont know who took it! - StepMania Forums] {{webarchive|url=https://web.archive.org/web/20071013041138/http://www.stepmania.com/boards/viewtopic.php?t=4063 |date=2007-10-13 }}</ref><ref>[http://www.stepmania.com/forums/showpost.php?p=70791&postcount=14 StepMania Forums - View Single Post - 20070310|Dokodemo Kawaii] {{webarchive|url=https://web.archive.org/web/20081216124423/http://www.stepmania.com/forums/showpost.php?p=70791&postcount=14 |date=2008-12-16 }}</ref>), the entry may be disqualified.

The scoring is determined by the overall quality of the song, steps and graphics.<ref>[http://www.stepmaniawiki.com/wiki/StepMix_4_Contest#Judging StepMix 4 Contest Judging] {{webarchive|url=https://web.archive.org/web/20080819182452/http://www.stepmaniawiki.com/wiki/StepMix_4_Contest |date=2008-08-19 }}</ref>
