SoundCraft - Framework for Transducing a StarCraft 2 Game¶ ↑

SOUNDCRAFT IN ACTION¶ ↑

Watch this quick demo video the SoundCraft framework in its first performance piece - GG Music!

RUNNING SOUNDCRAFT¶ ↑

1. Clone this repository onto your computer.

2. Run bundle install from the root of the directory to get the required gems.

3. Run ruby bank_parser.rb to start the bank parser/OSC dispatcher.

4. Run any programs that will receive OSC messages (the audio folder contains our sample audio implementation)

5. Play the custom maps from the Galaxy Editor or upload it to StarCraft 2 and play it from there!

FILES¶ ↑

• maps folder - Contains maps featuring the custom data-collecting triggers created for SoundCraft; play against an AI opponent when played from the Galaxy Editor or publish this map and play against others online

• bank_parser.rb - Ruby script that parses the XML bank files written by our custom map and dispatches OSC messages

• audio folder - our sample sonic mappings written in ChucK that receives OSC messages from the bank parser to produce sound

DATA FLOW¶ ↑

User data is collected as events occur (e.g. minerals collected, units die) or at fixed polling intervals (collecting APM, unit build progress) and written to XML bank files. Unfortunately, this is the only legitimate way to get data out of StarCraft 2, but the latency was found to be acceptable given we can control how often we poll for changes to these bank files. A Ruby script monitors the folder containing the bank files using guard/listen and when those files are modified, the XML files are parsed using Nokogiri and OSC messages are dispatched. Any OSC listener can catch those messages and process them to display data or produce sound.

If PRINT_DATA is defined in bank_parser.rb, data for each OSC message sent will be printed out. The print statements include the time in seconds since the program started running, OSC address, tags, and content sent. A blank line will be printed after an entire XML bank has been parsed. Debug print statements be disabled for live performances, but can be useful while developing. Here is some sample output for reference:
