Multiple Touch - How To?

Hi All,

Here's a script that reports all the lines in a notecard, but how do I get it to stop after it has read out the first line, and wait ti be clicked before reading out the next? Any ideas gratefully received...

string NotecardName = "speakme"; // notecard to read out
integer NotecardLine = 0; // line of notecard to start at
key NotecardQueryID; // dataserver query id

default {
state_entry() {
NotecardQueryID = llGetNotecardLine(NotecardName, NotecardLine);
}

dataserver(key query_id, string data) {
if (query_id == NotecardQueryID) {
if (data != EOF) {
llSay(0, ""+data);
++NotecardLine;
NotecardQueryID = llGetNotecardLine(NotecardName, NotecardLine);
}
}
}
}




Thanks in advance

use php tags - in [ and ] and with a / to make your code easier to read on the fora please!

But anyway, I've not tested it, but something like this should help:

integer pointer=0;
string cardName="myCard";
default
{
    touch_start(integer num)
    {
        llGetNotecardLine(cardName, pointer);
    }
    dataserver(key id, string data)
    {
        if(data==EOF)
        {
            pointer=0;
            llGetNotecardLine(cardName, pointer);
        } else
        {
            llSay(0, data);
        }
    }
}

Eloise,

Thanks for that, and sorry for not formatting the code properly. I've added a:

++pointer;

under:

llSay(0, data);

to increment the line number each time the object is clicked and a line is read out. Is this the right way of going about it? It works - just wanted to check that this is the most efficient way.

Pretty much yes ^^ it's possible to make it a bit more tricky:

touch_start(integer num) {

    llGetNotecardLine( cardName, pointer++ );
} 

which should read the card line, then increase the pointer variable by one... it's a small saving though and can make the code somewhat less readable after a while, so not sure if worth the trouble. Increasing variable in separate line makes it more obvious so i'd go with that. o.O

I'd probably do it with ++pointer under llSay... but Jonnah's way works just fine.

The reason I'd do it the other way... easier to debug. As you can see, even in short scripts like this is easy to make dumb mistakes.
