Bar Camp08 Guitar Hero Clone

How to build a Guitar Hero/Rock band clone in a week Rob Kischuk @rkischuk | http://blog.kischuk.com

What’s already out there? • JamLegend - http://jamlegend.com • Obviously - Guitar Hero, Rock Band, etc. • Frets on Fire - a good head start

Why Do this? • Hacking Fun Of It Launch a JamLegend Competitor • Marketing Sites Mini-game

Day 1 - MIDI (or - Are you sure?) • Goal - know MIDI cold • Tools - http://fretsonfire.net, Hex Editor (HexEdit), Audio Player, Audacity • http://faydoc.tripod.com/formats/mid.htm Dig into the spec, understand it, read it like The Matrix • FoF Song - small metadata file, .ogg audio file, MIDI sequencing

Day 2 - Get Your MIDI On • Goal: Recognize most Frets on Fire songs with plausible results and no errors Draw some boundaries - start with one single track • Find the language of your choice & write a parser - no OS alternative? • Find a few Frets on Fire tracked songs that you don’t mind listening to a billion times Transcode the song (if needed) • Pay attention to “running mode”

Day 3 - Verify With a UI • Goal: Work out the kinks and imperfections between your parser and what _should_ show up Store your parsed midi data in a format that is going to suit your UI language • Play the audio and find a way to represent the notes in sync with the audio In Flash, better to build an absolute timeline for note data and base notes off of playback progress

Day 4 - Build Out the UI • Goal: Display all notes in synch with the music Show the notes that are coming and confirm that they hit them • Key Considerations • how to display longer notes? How forgiving do you want to be • To strum or not to strum?

Day 5 - Time For A Scoring System • Goal: Award a score for how well the user did Point per note • How much for held notes? • Bonus multipliers? • Extra Credit: “Star Power”

Day 6/7 - What Now? • High Scores Song Selector • Add more instruments (Drums, cow bell?) • Vocals (Midi does have a Karaoke Format) • Sequence Your Own Songs - http://fretsonfire.wikidot.com/
