schusslig 1.7 beta

My piece "schusslig 1.7 beta" was shown at the open days of the Academy of Media Arts Cologne. It consists of an abstract 2D bullet hell shoot'em'up game (Psyvariar meets Pong) written in Lua (the engine is about 500 lines of pure Lua, to be published later), graphics projected with Gem and sonified with Pd (with some game sounds courtesy of Obiwannabe) for you to survive.

The piece was shown on a 60 speaker sound wall called 16:9 by Martin Rumori and Daniel Teige. The sound of each game character was "panned" to the nearest of the 60 speakers, so you could actually hear the bullets approach and your ship move.

Pictures don't do it justice but here are some. I also hope to get a video soon, but of course only stereo, not 60 channel. The black dots on the screen are the speakers:

The violet pattern is called "flower"

The game gets faster if you survive longer than 25 seconds. The yellow/red circle on the left with the read line is you, currently firing a laser:

It gets faster again at 30 sec.

Some technical info

Actually the real format of the wall is more like 22:9 instead of 16:9. The projection was 1920px wide. One machine has the game engine and the graphics running (dual screen for two projectors), a second machine with three soundcards drove the speaker wall. This was a Mac OS-X machine because we had to use one RME Fireface which isn't supported on Linux. That's bad customer service, RME: We want to run Linux everywhere. Soundcard access was made with a SVN built of Jackdmp. The two Pd instances communicated with netsend/netreceive.

As a controller I used a PS2 arcade joystick with a PS2->USB converter. Because we had problems with the [hid] object in Pd on OS-X (for unknown reasons the controller became stuck from time to time), we actually used a third machine - finally one with Linux - where the [joystick] object was available just for the controller. Again data was sent with netsend.

Unsharp picture, but with humans for size comparison.

The best high score I saw during the four days the installation was open was 1481 points.
