sensor

Description

Event: sensor( integer num_detected ){ ; }

13	Event ID
	Delay

Results from a call to either llSensor or llSensorRepeat.

• integer

num_detected

–

number of objects/avatars found

The results are ordered from nearest to furthest.
num_detected is always greater than zero, the no_sensor event is triggered if no objects/avatars were found.

Caveats

• Lindens in administrative mode cannot be sensed by sensors in the same region as the Linden.
• When used in an object attached to an avatar, the sensor occurs not at the object, but at the avatar.
• A sensor running in an attachment will not detect the avatar wearing it.

Examples

<lsl>float range = 10.0; // meters

default {

   touch_start(integer numberDetected)
   {
        llSensor("", "", AGENT, range, PI); // activates the sensor.
        // look for avatars (i.e. not moving objects) on all sides of the object
   }
   
   sensor (integer numberDetected)
   {
       string msg = "Detected " + (string)numberDetected + " avatar(s): " + llDetectedName(0);
       integer i = 0;
       while(numberDetected > ++i)//skips the first item which suits this application
       {
           msg += ", " + llDetectedName(i);
       }
       llWhisper(0, msg);
   }
   
   no_sensor()
   {
       llWhisper(0, "Nobody is near me at present.");
   }
