I would just like a notecard, to be able to be read and for a script to be able to define something using that line, A settings notecard!

integer time = notecardline 1

Or something, i have tried experimenting with the dataserver, but i cant get my head around it.

Thanks for any help in advanced.

here is a simple script that reads a notecard (that can be found on the wiki: llGetNotecardLine)
CODE

string gName = "Testnotecard";    // name of a notecard in the object's inventory
integer gLine = 0;        // current line number
key gQueryID; // id used to identify dataserver queries

default {
    state_entry() {
        gQueryID = llGetNotecardLine(gName, gLine);    // request first line
    }

    dataserver(key query_id, string data) {
        if (query_id == gQueryID) {
            if (data != EOF) {    // not at the end of the notecard
                llSay(0, (string)line+": "+data);    // output the line
                ++gLine;                // increase line count
                gQueryID = llGetNotecardLine(gName, gLine);    // request next line
            }
        }
    }
}

To only read one line of the notecard, change the code just a bit...

CODE

string gName = "Testnotecard";    // name of a notecard in the object's inventory 
integer gLine = 0;        // current line number 
key gQueryID; // id used to identify dataserver queries 

default { 
    state_entry() { 
        gQueryID = llGetNotecardLine(gName, gLine);    // request first line 
    } 

    dataserver(key query_id, string data) 
    { 
        if (query_id == gQueryID) 
        { 
            if (data != EOF) 
                {    
                llSay(0, (string)line+": "+data);    
                } 
        } 
    } 
}


BAsically...just take the read all lines loop out.

Am I missing something?

Where did the variable "line" come from in the llSay statement:
CODE
                llSay(0, (string)line+": "+data);


Is that a type for gLine? Or am I just not understanding or missing something?

I see its the same in the Wiki example, so I presume I'm missing something and its not a typo...

But would like someone to tell me what I'm missing!

Thanks! :confused:

i'm very sorry about that, your right it should be gLine, i've corrected the example

CODE

string gName = "Testnotecard";    // name of a notecard in the object's inventory
integer gLine = 0;        // current line number
key gQueryID; // id used to identify dataserver queries

default {
    state_entry() {
        gQueryID = llGetNotecardLine(gName, gLine);    // request first line
    }

    dataserver(key query_id, string data) {
        if (query_id == gQueryID) {
            if (data != EOF) {    // not at the end of the notecard
                llSay(0, (string)gLine+": "+data);    // output the line
                ++gLine;                // increase line count
                gQueryID = llGetNotecardLine(gName, gLine);    // request next line
            }
        }
    }
}

Well, I had the same problem getting a grip on how it works, so I'll share too in a bit more direct way than using the wiki example. I think it makes more sense to see a couple lines than just one, but just cut out the extra to get what you need.

Say you want to read line numbers 2 and 4....


CODE

string card_name = "your_notecard";
key query_line_two;   //create a query id for line two
key query_line_four;  //create a query id for line four

default 
{
    state_entry() 
   {
       //Here we set up two queries to the notecard.  One to line 2, one to line 4
        query_line_two = llGetNotecardLine(card_name, 2);    // request line 2
        query_line_four = llGetNotecardLine(card_name, 4);  //Same deal, line 4
    }

    dataserver(key query_id, string data) 
    {
        //What to do when you "run" your queries
        //The if statement checks to see which query you want by comparing keys
        //of course, in the state entry we've said we want both, so as each request
        //is processed, the correct action is taken
        //You could add an "if (data != EOF)" if you wanted, but it's redundant IMO 
        //since you are calling a known line

        if (query_id == query_line_two)  llSay(0, "line two: " + data); 
        else if (query_id == query_line_four)  llSay(0, "line four: " + data); 

    }
}



I hope this makes sense and is a bit more intuitive.

You guys are just pulling my leg right, (thouh I know how hard it is to avoid typos :-)

I presume Sol wanted to say instead of:



CODE

query_line_two = llGetNotecardLine(card_name, 2);    // request line 2 
query_line_two = llGetNotecardLine(card_name, 4);  //Same deal, line 4


Sol had a typo for the second line and meant to say:

CODE

query_line_two = llGetNotecardLine(card_name, 2);    // request line 2 
query_line_four = llGetNotecardLine(card_name, 4);  //Same deal, line 4

Oops, yes. Thank you. Cut/paste can also be your enemy! =)
Fixed it in the code.
