YES! Audio prototyping builds of games exist! Now just to get a copy working on a school computer without any of the ultra-violence. Sounds like a summer project to me!
This particular one works with a special demo build of Quake 3 Arena that sends OSC messages over a network connection to PD. I’m sure there are other implementations out there too. This would enable students to program action sounds like footsteps and firing a weapon, but also would enable music ‘scene changes’ such as creepier music upon entering a dungeon, for instance. I’M SO GLAD THIS EXISTS!!!
