Changeset 5878 for code/branches/core5

Timestamp:

Oct 5, 2009, 1:36:33 AM (15 years ago)

Author:

Message:

Added GameMode::playsSound(). This function checks whether sound is available. You MUST NEVER assume that the SoundManager exists and ALWAYS check it (even if graphics is all loaded).
Also cleaned SoundManager c'tor to use Exceptions.
