you can do it...but its not a supported feature of c2
first off, ALL of your sounds need to be grabbed this way, cannot have any sounds within c2.
when you export your project (html5 web for instance) ....
- open the the data.js file in your favorite text editor and find "/media" (towards the bottom) and change it to "http://www.yoursite.com"
when calling the audio from the c2 audio plug in:
- use play (by name)
- in the "audio file name" put your file path "/myGameSounds/laserShot"
hope this helps!
