AVsitter1 LSL Examples (Advanced)

/******************************************************************
 * This AVsitter™ example will start a sequence of animations when a BUTTON is pressed on the menu.
 * Alternately, the sequence can start automatically when a set number of avatars sit (see AVATARS_TRIGGER below).
 * If you have multiple sequences in your furniture you can use one copy of this script for each sequence.
 * The script will stop playing the sequence when any new animation or sequence is selected with the menu.
 * Please read the notes for each setting below.
******************************************************************/

// SEQUENCE_NAME should match the BUTTON name in your AVpos notecard you are using to trigger the sequence.
string SEQUENCE_NAME = "Sequence1";

// SEQUENCE_POSES is the list of POSES you want in the sequence. These should match the menu names you have given the poses, not the animation names. If using a SYNC pose, place "S:" in front of the name.
list SEQUENCE_POSES = ["S:couples1","S:couples2","Sit1","Sit2"];

// SEQUENCE_TIMES lists how long each pose will be played in seconds, and should match the list length of SEQUENCE_POSES.
list SEQUENCE_TIMES = [5,5,5,5];

// SEQUENCE_LINKNUMBER should match the sequence trigger BUTTON's link number (should be the same for all sequences) e.g. BUTTON Sequence1|99
integer SEQUENCE_LINKNUMBER=99;

// REPEAT_SEQUENCE can be set to TRUE or FALSE depending on if you want the sequence to loop back to the beginning.
integer REPEAT_SEQUENCE = TRUE;

// AVATARS_TRIGGER can auto-trigger the sequence when a certain number of avatars are sitting. e.g. AVATARS_TRIGGER = 2;
integer AVATARS_TRIGGER = FALSE;

// VERBOSE simply controls if you want the script to say "Sequence Stopped!" and "Sequence Started!" in local chat.
integer VERBOSE = TRUE;

/******************************************************************
* This AVsitter™ example will auto-play a SYNC pose when 2 avatars sit,
* and automatically play a different POSE when 1 avatar stands up.
* (This is for a two person cuddle chair in mind)
* We'll say for this example that the two animations are as follows:
*            1: a SYNC animation named "Close"
*            2: a POSE called "Sit1"
* Note that the "S:" is required to play the SYNC animation
