Question

I have a notecard with a different word on each line, and I’d like to be able to select from the lines randomly. How can I do that?

Answer 1

First, as you mention, you need a notecard. For this example, I’m using one named “colors” with the following contents:

red
blue
green
yellow
orange
purple

With that notecard present, the following script will read and chat a random line from the card each time the prim is touched.

//this script will grab and chat a random line from the "colors" notecard each time the prim is touched.

string card = "colors";
key linecountid;
key lineid;
integer linemax;

integer random_integer( integer min, integer max )
{
  return min + (integer)( llFrand( max - min + 1 ) );
}


default
{
    state_entry()
    {
        //get the number of notecard lines
        linecountid = llGetNumberOfNotecardLines(card);
    }

    touch_start(integer total_number)
    {
        lineid = llGetNotecardLine(card, random_integer(0, linemax));
    }

    dataserver(key id, string data)
    {
        if (id == linecountid)
        {
            linemax = (integer)data - 1;
        }
        else if (id == lineid)
        {
            llSay(0, data);
        }
    }
}
