homing device

I have a jeep. I would like to add some "homing" script that beeps (or something) as it gets closer to a known object (x,y,z).

Can anyone point me to a script that does something like this that I can modify.

Thanks

sue dough code...

CODE

vector T = < x,y,z>;
float close=255;


default
{
state_entry()
{
     llSettimerEvent(10);
}

timer(...)
{
      if( llVecDist( llGetPos(), T) < close )
      {
             ***Beep***
             close = llVecDist( llGetPos(), T);
     }
}

My interpretation was that Nichiren wanted something more like a Geigger counter. Maybe just keep checking the distance and altering a timer interval, like:

CODE

vector T = < x,y,z>;

default
{
     state_entry()
     {
          // Just to get the timer going
          llSetTimerEvent(1);
     }

     timer(...)
     {
          // Get the current distance to target
          float dist = llVecDist( llGetPos(), T);
     
          // Make the beep noise

          // Set pause before next beep
          if (dist < 1) llSetTimerEvent(0.2);
          else if (dist < 3) llSetTimerEvent(0.4);
          else if (dist < 5) llSetTimerEvent(1.0);
          else if (dist < 9) llSetTimerEvent(2.0);
          else llSettimerEvent(3.0);
     }
}


Or do some maths to convert the target distance to a time interval, so you get a smoother transition, e.g. timePulse = dist/10.0. Be sure to set a reasonable lower limit though; it could already be a lag-inducing script.

Getting error :name not defined within scope on the last ELSE statement. I noticed that
the SettimerEvent on that line is not colored liked the ELSE IF statements. any clue what is wrong?

vector T = < 118,245,57>;
float gap = 2.0;

default
{
state_entry()
{
// Just to get the timer going
llSetTimerEvent(gap);
}

timer()
{
// Get the current distance to target
float dist = llVecDist( llGetPos(), T);

// Make the beep noise

// Set pause before next beep
if (dist < 1) llSetTimerEvent(0.2);
else if (dist < 3) llSetTimerEvent(0.4);
else if (dist < 5) llSetTimerEvent(1.0);
else if (dist < 9) llSetTimerEvent(2.0);
else llSettimerEvent(3.0);
}
}

else llSettimerEvent(3.0); should probably be else llSetTimerEvent(3.0); :p

modified to use touch as a start/stop mechanism.

CODE

vector T = < x,y,z>;
integer running=1;

default{
     state_entry(){
          // Just to get the timer going
          llSetTimerEvent(1);
     }

     timer(...){
          // Get the current distance to target
          float dist = llVecDist( llGetPos(), T);
     
          // Make the beep noise

          // Set pause before next beep
          if (dist < 1) llSetTimerEvent(0.2);
          else if (dist < 3) llSetTimerEvent(0.4);
          else if (dist < 5) llSetTimerEvent(1.0);
          else if (dist < 9) llSetTimerEvent(2.0);
          else llSetTimerEvent(3.0);
     }

     touch_start(integer touches){
          integer i=0;
          do{
               if(llDetectedKey(i)==llGetOwner()){
                    if(running){
                         llSetTimerEvent(0);
                         running=0;
                    }else{
                         llSetTimerEvent(1);
                         running=1;
                    }
               }
               i++;
          } while(i<touches);
     }

}

Thanks..I will go try this now.

I have also played with trying to turn the beeping off if it is out of reasonable distance.
For some reason the code below turns it off..but permanently. even when I am right on the x,y,z. due..to the >9 statement.


// Set pause before next beep
if (dist < 1) llSetTimerEvent(0.2);
else if (dist < 3) llSetTimerEvent(0.4);
else if (dist < 5) llSetTimerEvent(1.0);
else if (dist > 9) llSetTimerEvent(0);

else llSetTimerEvent(3.0);

Yep setting timer to 0 turns it off.

Did you solve your problem?

Don't call llSetTimer(0) or it will never enter the timer funciton again to check distance. Instead just use an IF statement to stop it playing the sound over a certain distance.

e.g.

if (dist<9) llPlaySound(...);
