llDetectedPos

Summary

Function: vector llDetectedPos( integer number );

35	Function ID
0.0	Forced Delay
10.0	Energy

Returns a vector that is the position (in region coordinates) of detected object number.

• integer

number

–

Index of detection information

number does not support negative indexes. Returns <0.0, 0.0, 0.0> if number is not valid sensed object.

Specification

llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.

Caveats

• If number is out of bounds this function returns <0.0, 0.0, 0.0> and the script continues to execute without an error message.
• Events that enable the llDetected* functions always return at least one detected item.
  • Detection events are not raised if there is nothing detected.^[1]
  • The detection event's items detected parameter is initially never less than 1.^[2]

<lsl>// get name and sim position of Avatars within "say" range

default {

       llSensor( "", "", AGENT, 20, PI );
   }

   sensor( integer vIntFound )

       integer vIntCounter = 0;
       //-- loop through all avatars found
       do

               + (string) llDetectedPos( vIntCounter ) );
       } while (++vIntCounter < vIntFound); 
   }

   // sensor does not detect owner if it's attached
   no_sensor()
   {
       llOwnerSay( "I couldn't find anybody" );
   }

1. ^ The exception is no_sensor but it doesn't enable llDetected* functions.
2. ^ Like all event parameters, the user can overwrite the initial value.
