**
|
||||
** A SoundSequence actor has two modes of operation:
|
||||
**
|
||||
** 1. If the sound sequence assigned to it has a slot, then a separate
|
||||
** SoundSequenceSlot actor is spawned (if not already present), and
|
||||
** this actor's sound sequence is added to its list of choices. This
|
||||
** actor is then destroyed, never to be heard from again. The sound
|
||||
** sequence for the slot is automatically played on the new
|
||||
** SoundSequenceSlot actor, and it should at some point execute the
|
||||
** randomsequence command so that it can pick one of the other
|
||||
** sequences to play. The slot sequence should also end with restart
|
||||
** so that more than one sequence will have a chance to play.
|
||||
**
|
||||
** In this mode, it is very much like world $ambient sounds defined
|
||||
** in SNDINFO but more flexible.
|
||||
**
|
||||
** 2. If the sound sequence assigned to it has no slot, then it will play
|
||||
** the sequence when activated and cease playing the sequence when
|
||||
** deactivated.
|
||||
**
|
||||
** In this mode, it is very much like point $ambient sounds defined
|
||||
** in SNDINFO but more flexible.
|
||||
**
|
||||
** To assign a sound sequence, set the SoundSequence's first argument to
|
||||
** the ID of the corresponding environment sequence you want to use. If
|
||||
** that sequence is a multiple-choice sequence, then the second argument
|
||||
** selects which choice it picks.
