Instructions


each line is in the format of:<br>
<time>|<color>|<text><br>
for example<br>
3|<1,1,1>|testing text<br>
will display a white "testing text" for 3 seconds.
IMPORTANT INFORMATION:
Each line in the notecard cannot be more than 255 characters in length. That includes the timer interval, color, and "|" symbols.
Do not use "|" symbols anywhere in your text. It is used to determind where timer, color, and text begin.
The names of the notecards cannot be more than 24 characters in length.
Do not have any empty lines in the notecard or lines in the wrong format
I have provided some sample notecards. Each sample contains a line that has numbers such as 012345678901234 as the text.. these lines are 255 characters in length.
One of the sample notecards is named similarily. It is 24 characters in length.
The Script:
<lsl>
vector defcolor = <1,1,1>; //default color, used for the infoline.
string infoline = "Click me for Info"; //infoline self-explanatory I think.
integer wrap = 40;  //how many characters to wrap at for word-wrapping
//shouldnt need to edit below this line
key qID; //key of notecard for dataserver event
integer linenum; //current line to read
string notecard; //current selected notecard
integer num_cards; //total number of notecards
integer chan;      //channel to listen on for dialog
integer MenuOffset; //offset for when there are too many notecards to show in one menu.
key currUser;      //currUser of menu
//this function takes the notecard line, parses it, and sets appropriate text and timer.
setMsg(string data)
{
    list tmp = llParseString2List(data,["|"],[]); //parse the line
    float interval = (float)llList2String(tmp,0); //time interval (first entry)
    vector color = (vector)llList2String(tmp,1);  //color (second entry)
    string msg = llList2String(tmp,2);            //the msg itself (third entry)
    msg = format(msg); //this function formats the message (word wrapping)
    llSetText(msg,color,1.0);  //set the text.
    llSetTimerEvent(interval);  //set the timer.
}
//returns a word wrapped string based on passed in value s.
string format(string s)

    integer i = 0; //iterator for our loops
    string tmp;    //used for a substring checking for spaces
    integer j;      //iterator for our nested loop
    //if the length is greater than the wrap size then we need to insert \n's
    //otherwise we will just return the string unmodified
    if(len > wrap) 
    {
        //in the interest of making this function faster we are going to check
        //to see if the string has no spaces at all.. if it does we will simply
        //insert \n's at the wrap setting and then return.
        if(llSubStringIndex(s," ") == -1) //check for spaces

        i = 0; //set our interator at 0.
        do //this loop, like the one above, loops as many times as len / wrap
        {
            j = i * wrap; //j is the index of where to start wrapping from
            //this loop moves backwards from j till it finds a space it then
            //inserts a \n and starts the loop again from the next index.
