simple scanner bug

Hello, i've this simple scanner script with a bug inside...its attached on me and if i type "/1list" give me the list of agents near me (range 96mt), and this is exactly what i want from this script..xD

but sometimes, when i change sim or simply relog, keep in memory the last scanning data..
i call "bug" this issue but i'm sure that is a programming fault...

string data ;
key lastOwner;

default {
    
    attach(key id) {
        llOwnerSay("type /1 list on chat to start the scanning");
        if(lastOwner!=llGetOwner()) {
            llResetScript();
        }
    }
    
  state_entry() {
   lastOwner=llGetOwner();
   llSetAlpha(0.0, ALL_SIDES);
   llSensorRepeat("", NULL_KEY, AGENT, 96.0, 2*PI, 0.1);
   llListen(1,"",llGetOwner(),"");
   }

  sensor(integer num_detected) {
     data = "--" + (string)num_detected + " agents detected 96mt--\n "; 

     integer p = 0;
     for(p = 0; p< num_detected; ++p) {
         string status = ""; 
         integer s = llGetAgentInfo( llDetectedKey(p) );

         if(s & AGENT_AWAY){status += "A ";} 
         if(s & AGENT_BUSY){status += "B ";}
         if(s & (AGENT_FLYING | AGENT_IN_AIR)){status += "F ";}
         if(s & AGENT_MOUSELOOK){status += "M ";}
         if(s & AGENT_ON_OBJECT){status += "O ";}
         if(s & AGENT_SITTING){status += "S ";}
         if(s & AGENT_TYPING){status += "T ";}
         if(s & AGENT_WALKING){status += "W ";}
      data += llDetectedName(p) + " (" + (string)llRound(llVecDist(llDetectedPos(p), llGetPos())) + "m) " + status + "\n ";
        }
    }
    
    listen(integer a, string b, key c, string msg) {
        if(msg == "list") {
            llOwnerSay(data);
        }
    } 
}

I'm not really clear what you're saying the problem is but...

The 'data' gets refreshed with every scan, which is set VERY aggressively. At 0.1 seconds per scan I doubt the code even has time to compile its list before it has queued several further scans.

I would try triggering the scan from the command:

default
{
state_entry()
{
llSetAlpha(0.0, ALL_SIDES);
llListen(1,"",llGetOwner(),"";
}

attach(key id)
{
llOwnerSay("type /1 list on chat to start the scanning";
}

listen(integer a, string b, key c, string msg)
{
if(msg == "list" llSensor("", NULL_KEY, AGENT, 96, TWO_PI);
}

sensor(integer num_detected)
{
llOwnerSay("--" + (string)num_detected + " agents detected 96mt--";

integer p = 0;
for(p = 0; p< num_detected; ++p)
{
string status = "";
integer s = llGetAgentInfo( llDetectedKey(p) );

if(s & AGENT_AWAY){status += "A ";}
if(s & AGENT_BUSY){status += "B ";}
if(s & (AGENT_FLYING | AGENT_IN_AIR)){status += "F ";}
if(s & AGENT_MOUSELOOK){status += "M ";}
if(s & AGENT_ON_OBJECT){status += "O ";}
if(s & AGENT_SITTING){status += "S ";}
if(s & AGENT_TYPING){status += "T ";}
if(s & AGENT_WALKING){status += "W ";}
llOwnerSay(llDetectedName(p) + " (" + (string)llRound(llVecDist(llDetectedPos(p), llGetPos())) + "m) " + status);
}
}

changed(integer change)
{
if(change & CHANGED_OWNER) llResetScript();
}
}

...and the Lag Monster won't thank you, but everyone else will!

thx Pale!!...now work perfectly..xD

the code is object orientated.
the timer floods the query and the datas-variables get out of sync with the variable-data processing.

In practice, fast timers and sensors actually don't really get out of sync.
