Realms in Time - Programmable Song Player ( V2 )

Programmable Song Player ( V2 )

Published: 03 August 2013

Written by Kitsune

Due the the 10 second limit on sounds we need to play whole songs as a sequence of clips. This does that.

You can add up to 11 (inclusive) complete songs (however many sound files there are per song) and select which to play.
If a song is playing you can select the next to play and a playlist is formed. The playlist can be added to at anytime during playback.
The volume is adjustable at anytime, including during playback.
Reads the song snippets from the sound files placed in the object inventory. They will be played in alphabetical/numerical order.

Follow the instructions at the top of the script. Very little editing is needed.

There is a chance that the memory will break if the playlist is made too long. V3 will include a measure against that but I have to sleep occasionally.

// V2 //
 
// This list is all you need to edit. List the names of the songs (each collection of sound files that makes one song)
// followed by the length of those sound clips (each song should contain clips of equal length)
 
// The list should be structured like so -
 
// list songs = ["First Song", 9.0, "Second Song", 9.65, "Third Song", 9.45];
 
// The names of the songs must be identical to some part of the sound files used for that song like so -
 
//// In the prim inventory (along with this script) -
 
////// Box_Of_Rain_wav_1
////// Box_Of_Rain_wav_2
////// Box_Of_Rain_wav_3
////// Servant 1
////// Servant 2
////// Servant 3
 
//// In the script -
 
////// list songs = ["Box_Of_Rain", 9.2, "Servant", 9.8];
 
// The script will play the clips in alpha/numerical order so name them wisely.
