== Theme ==

The theme for this challenge is "One Way Trip." So there.

== Coordination ==

'''Face-to-face:''' we will kick this off on Sunday, 2012-09-09 around 5pm at the [[http://metalab.at/|Metalab]]. The time is only tentative, so watch this page for last-minute updates. Another get-together will probably follow on Monday.

'''Email:''' we are going to hijack the [[MailingLists|PyUGAT discuss mailing list]] for the duration.

'''Chat:''' come to our [[http://webchat.freenode.net/?channels=%23pyugat|IRC channel on freenode]].

== Idea ==

Something like [[https://www.youtube.com/watch?v=m0CbuRX02Bs|Jump'n'Roll]], [[https://www.youtube.com/watch?v=F6Rovi9QSDk|Skyroads]], the Bit.Trip games or even "Guitar Hero." Something that scrolls back to front, gameplay consists mainly of learning long sequences of moves, the rhythm of the soundtrack may influence the gameplay or may depend on it. ([[kirill]], [[hop]])

== Design: Whales ==

Whales, ocean, submarines, petunias!, under water

== Gameplay ==
After the first meeting we are trending towards the "underwater" theme due to it's novelty.

The gameplay consists of the world advancing onto the player front-to-back (as in Skyroads, Desert Bus). Occasional '''Goodies''' that the player has to collect and '''Baddies''' that the player has to avoid advance on the player as the level progresses. Due to perspective, as objects get closer they get bigger.

Top 10% of screen is above water - for deco. Bottom 30% - sea ground. The middle - the playable area. The 20% on either side are not accessible to the player.

Some possible entities (deco or game-affecting): starfish, divers, whales, sharks, dolphins, mermaids, seahorses, shells, bubbles, seaweed, ...

== Story ==
Something about the love of a Whale and a Submarine? Maybe a robotic-whale-submarine-villain kidnapped the whale's girlfriend? :)


== Prerequisits ==

=== PyGame (before 2016) ===

Installing PyGame on OS X with SDL from homebrew takes some fiddling. Follow this guide: http://www.daskrachen.com/2011/03/installing-pygame-using-homebrew.html

=== SDL2/SDL2_mixer/OpenGL (2016) ===

The current default branch on our Mercurial repository doesn't depend on PyGame anymore. Instead, it has a self-contained "core" module that builds against SDL2, SDL2_mixer and OpenGL. On OS X, install the dependencies using:

{{{
brew install sdl2 sdl2_mixer
}}}

then build it using

{{{
make -C core
}}}

== Features ==
|| '''Feature''' || '''Priority''' ||
|| Scenes || High ||
|| Text skipping in scenes || High ||
|| Darker further enemies || Medium ||
|| Pearl counter (score) || High ||
|| Life indicator || High ||
|| Level Design || High !! ||
|| Enemies should disappear earlier || Low ||
|| Random Level || Low ||
|| Enemies size problem when close || Medium ||
