comparison engine/core/audio/soundemitter.h @ 487:7f1c42b66aa4

Moved the shooter demo Timer() class to helpers.py. Changed the formula that calculates the length of the audio clip to be correct. The shooter demo now demonstrates the use of the audio clip callbacks correctly. Fixed the fife_timer extension to actually work.
