need help with llMessageLinked

im good with scripting but new to sl, i would apprectiate any help on this. ive read that when making an object that consist of other objects, it reduces alot of sim lag if i use llmessage linked instead of talking about objects.

im having two problems with this, first, i tried to make it the main object talk to three other objects, but one seems to respond, and the other two dont. How would i seperate which object gets which message?

second, im sending a integer, but llmessagelinked works with strings. Ive found how to send a string of my integer, but how would i convert it back to integer on recieve end...


________heres a basic layout of send object code

// finds values for the three reels

integer r1;
integer r2;
integer r3;


default

{
touch_start(integer reels) // starts the number gen by touch

{
r1=llFloor(llFrand(22));
r2=llFloor(llFrand(22));
r3=llFloor(llFrand(22));
llOwnerSay((string)r1); // temp, tells me r1 val
llOwnerSay((string)r2); // temp, tells me r2 val
llOwnerSay((string)r3); // temp, tells me r3 val
state talking; // change to the "talking" state
}

}
state talking
{
state_entry()
{

llMessageLinked(-1, 0,(string)r1, "id";
state default;

}
}

________heres a basic layout of receive object code


// finds values for the three objects

integer r1;

default
{
// Waits for another script to send a link message.
link_message(integer sender_num, integer num, string str, key id)



{
llOwnerSay((string)str);





state default;
}
}

ive had a similar problem with sending a link message to all prims in an object, i resorted to referencing directly since there were only a couple of prims i needed to contact at the moment but it would be nice to know if anyone could shed some light on it.

To send a integer use the second parameter for llMessageLinked:

llMessageLinked(-1,10,"",id);

should send the integer 10 to all the prims.

well with 3 variables you can do:

integer r1;
 integer r2;
 integer r3;
 default{
 	touch_start(integer reels) // starts the number gen by touch
 	{
 		r1=llFloor(llFrand(22));
 		r2=llFloor(llFrand(22));
 		r3=llFloor(llFrand(22));
 		llOwnerSay((string)r1); // temp, tells me r1 val
 		llOwnerSay((string)r2); // temp, tells me r2 val
 		llOwnerSay((string)r3); // temp, tells me r3 val
 		llMessageLinked(LINK_SET, r1,(string)r2,(string)r3);
 	}
 }
 
 // finds values for the three objects
 
 
 default{
 // Waits for another script to send a link message.
 	link_message(integer sender_num, integer num, string str, key id){
 		llOwnerSay((string)num);
 		llOwnerSay(str);
 		llOwnerSay((string)id);
 	}
 }
 
 

You seem to have alot of unneeded code in yours

I guess you have seen the wiki on this:
http://secondlife.com/badgeo/wakka.php?wakka=llMessageLinked

Notice that it is better to use LINK_SET rather than -1. Note the other constants.



As for your other questions:
1. Put in llOwnerSay statements in each linked prim so you can see what is going on. You would need to preface each statement with the name of the script it is in. Make sure you use the correct LINK_X constant.

   link_message(integer sender_num, integer num, string str, key id)
    {
        llOwnerSay("Script name " +
                         " sender_num=" + (string) sender_num +
                         " num="             + (string) num +
                         " str="               +  str +
                          " key="             + (string) key);
    }

2. just use "integer) str" to extract the number.

I also use if statements to make different scripts respond to different ranges of num.

hth (the above code not tested in world)

I'm not shure about the rest of the problem, but you seem to have some confusion between objects and primitives.

1. Objects are built from one or more primitives.
   
2. llmessageLinked only works between scripts in primitives within the same object.
   

Does this help clear things up? [I hope so!]


Toodle-oo!

i understand difference between objects and primitivtes, ive just been up without sleep all night trying to get it to work

my problem is i have the three variables for now (maybe more later)
and i want each prim to get and use 1 variable

now i know using the typed out constant is ezer for ppl begining the wild world of LSL but other than that how is it better?

okay Pru Xingjian & ed44 Gupte helped me get each of three prims to have seperate integer passed to it,

i just seperated each prim to part of the message, for eample prim1


default
{
link_message(integer sender_num, integer num, string str, key id){
llOwnerSay((string)num);
}

just uses the integer num, and prim2 uses the string num, etc

**this still leaves the question of how do i then revert thewse three items
integer num, string str, and ket id back to integer a, b, c

and new question

this seems like a shortcut way, it might be the only way that works, but it only has rom for three variables. what if i want to work with say 6 prims and 6 variables? is it possible?

i know i can do it with alk and listen, but im trying to doit this way to minimize the lag on my sim

you could do it with a list as a string.

in your root script you have a list ie:

list values = [1,4,9,3,4,9];

string str_values = llDumpList2String(values, "+"); // creates a string "1+4+9+3+4+9"

llMessageLinked(-1,0,str_values,id);

then for each child prim:

message(integer sender, integer num, string msg, key id)
{
   list values = llParseString2List(msg, ["+"],[]); //convert string back to list

...
...
...

with the list in the client you then just pull the value relevant to the prim its in, so if it is prim 2 you would need to take the second value from the list which would actually be position 1 within the list.

0 1 2 3 4 5
1+4+9+3+4+9

to convert back just use the relevant functions for lists.

integer r1 = llList2Integer(values[1])

Hope this makes sense, its 2am over here in UK and i can barely keep my eyes open.

that makes perfect sense, ill have to try that. thank you all for ur help... ill post again if i need more but i think with all ur ideas ill make it work

i like the possibilites the list strings will give me, that will allow me to have many things going on at the same time.

i run into one problem, on part of code

integer r1 = llList2Integer(values[1])

i get a syntax error between the s and [ after values
am i missing something?

Higher readability? doesn't really need more reason than that... ^^;

i took out he [] around the list name and it works... this is perfect, thanks
