Hey Professor. Sorry if it's been a while. I've been busy looking for a full time job. Hope all is well. I tried following what you said, but I got stuck. I watched Vimeo and adjusted the WeaponBlast file but that's where I'm confused. Back in Unity, the Blaster SFX section doesn't show up. I made an "Audio" section in the Hierarchy section, but I think I messed up the file selection. Were you sending me the audio files or was I just using the ones I made after using the website? For now I tried those but I'm still getting red errors. When you have a chance, let me know what you think. I'm available the rest of the week and weekend if you want to try a zoom session. 
Thanks, Brian McKenna
