Dialog menu ok, won't return values though

Thank you to everyone who helped me get this going, I went and added another feature that I ALSO can't seem to get working. I am feeling a bit on the frustrated and stupid side right now... I feel like I am learning things, and better ways to format my code, but lately it seems like I am losing my way... sorry to keep bugging everyone...

Here is the new code and information:

integer listPos; // Just to be sure I wasn't mising something... all main variables are now global.
vector targetPos;
integer channel = -10;
list avatarsDetected = [ ];
list keysDetected = [ ];
list posDetected = [ ];
string Gname;
string tool;
integer nextStep;
string nextAvatarName;
string nextAvatarKey;
vector nextAvatarPos;

string menuText = "Select the person to receive surprise coupon!!";

useKey(key targetKey)
{
//Just wanted to check my data, and lo and behold.. no targetPos...
llSay(0,(string)targetKey); //Returns valid key
llSay(0,(string)targetPos); //Returns <0,0,0> everytime no matter who you pick
llSay(0,(string)listPos); //Returns position in list (as far as I can tell it must be right since name and key match
llSay(0,Gname); //Returns correct name when clicked on Dialog Menu
//Since I got it working I thought it would be cool to rez a "coupon" next to a customer
//that would be of just whoever one randomly chose to be the lucky person that could get
//a full sale copy of an item in the store or something... kind of draw attention to things, etc.
//---You could even oversize your sale panel for a big effect I really like this idea the more
//I thought on it....
}

default
{
state_entry(){
llListen(channel, "", llGetOwner(), "";
}

link_message(integer sender_num, integer num, string str, key id)
{
if (str == "GetCustomer"{
llSensor("", NULL_KEY, AGENT, 30, PI);
}
}

listen(integer channel, string name, key id, string message)
{
Gname = message;
listPos = llListFindList(avatarsDetected, (list)message);
targetPos = llList2Vector(posDetected, listPos);
useKey(llList2Key(keysDetected, listPos));
}

sensor(integer numDetected)
{
if (numDetected > 12) numDetected = 12;
avatarsDetected = [ ];
keysDetected = [ ];
posDetected = [ ];

for (nextStep = 0; nextStep < numDetected; nextStep++)
{
nextAvatarName = llDetectedName(nextStep);
nextAvatarKey = llDetectedKey(nextStep);
nextAvatarPos = llDetectedPos(nextStep);

if (llStringLength(nextAvatarName) > 24) nextAvatarName = llGetSubString(nextAvatarName, 0, 23);
avatarsDetected = (avatarsDetected=[]) + avatarsDetected + nextAvatarName;
keysDetected = (keysDetected=[]) + keysDetected + nextAvatarKey;
posDetected = (posDetected=[]) + posDetected + (string)nextAvatarPos;
}

llDialog(llGetOwner(), menuText, avatarsDetected, channel);
}
}

Basically, all I added was a THIRD LIST.
All it is supposed to do is grab the vector position of the very SAME avatars it is already recording.
Granted I have never used the DetectedPos function before, but there really isn't much info on the wikki... from what I gleaned from it, and the fact that I didn't get any errors, I think it is right though on format.

All I get are zeros for vectors. Everything else works like it did before, so I am using the script as it sits just fine, but after I came up with the 'coupon / "Nth" visitor today' idea... I really like it.

Although I do plan to make a nifty gadget with this and the scripts linked to it, (Well basically a HUD with options for auto-rez inventory, updating your store, etc.) I plan to make this and everything publicly available because of everyones help. I can't thank everyone enough.

Take care,

You don't appear to have set up a listen. I would expect to see something like this:

llListen(channel, "", llGetOwner(), "";

...often to be found in state_entry() but not always.

Try setting

state_entry()
{
llListen(channel, "", NULL_KEY, "";
}

Worked for me in a test in LSL Editor, but resulted (in the test environment) in an error within the llList2Key()-call in listen(...) - maybe due to the test environment. But at least the listen(...) part is reached that way

Yep, that pretty much fixed it with a little extra tweaking on my end as well. I appreciate it, I knew it was something staring me in the face.. been working on it too long and needed to give up the ghost.

Thanks a mint!

I've added another bug to the system ... I have edited the original post with updated code and information... so sorry to bother anyone again, thanks for helping me out again.

Your bugs are getting cunning.


You start with this line:

posDetected = (posDetected=[]) + posDetected + (string)nextAvatarPos;

...where you put the llDetectedPos into the posDetected list as a string. So you have a list of strings. However, later on you try and transform this string into a vector:

targetPos = llList2Vector(posDetected, listPos);

...and then report it as a string:

llSay(0,(string)targetPos);


Now, I'm not going to defend this but the Wiki states (the Wiki I can get working just now):

I would suggest you simply collect the posDetected list as vectors:

posDetected = (posDetected=[]) + posDetected + (vector)nextAvatarPos;

...but I suspect there are several ways to skin this cat and I have no idea where you're going with this script.
