28 * Changed sound stuff to allow low memory usage.
29 * Also, changed so that Sounds isn't an array of digi_sounds, it
30 * is a ubyte pointing into GameSounds, this way the digi.c code that
31 * locks sounds won't accidentally unlock a sound that is already playing, but
32 * since it's Sounds[soundno] is different, it would erroneously be unlocked.
34 * Revision 1.27 1995/02/01 22:20:31 john

50 * Added max_distance passing for sound objects.
52 * Revision 1.21 1994/12/05 12:17:40 john
53 * Added code that locks/unlocks digital sounds on demand.
55 * Revision 1.20 1994/11/28 18:34:57 john
56 * Made the digi_max_channels cut of an old sound instead of
57 * not playing a new sound.
59 * Revision 1.19 1994/11/14 17:53:56 allender
60 * made some digi variables extern
62 * Revision 1.18 1994/10/28 14:42:58 john
63 * Added sound volumes to all sound calls.
65 * Revision 1.17 1994/10/11 15:25:37 john
66 * Added new function to play a sound once...
68 * Revision 1.16 1994/10/03 20:51:44 john

82 * because it doesn't work with MasterVolume stuff.
84 * Revision 1.12 1994/09/29 12:42:34 john
85 * Added sidenum to keep track of sound pos. Made sound functions
86 * not do anything if nosound. Made sounds_init delete currently
89 * Revision 1.11 1994/09/29 12:23:42 john
90 * Added digi_kill_sound_linked_to_segment function.
92 * Revision 1.10 1994/09/29 11:59:04 john
93 * Added digi_kill_sound
95 * Revision 1.9 1994/09/29 10:37:38 john
