Description
Event: sensor( integer num_detected ){ ; }| 13 | Event ID |
Results from a call to either llSensor or llSensorRepeat.
| • integer | num_detected | – | number of objects and avatars found |
The results are ordered from nearest to furthest. num_detected is never zero, the no_sensor event is triggered instead.
Caveats
Examples
<lsl>float range = 10.0; // metres
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
}

{
string msg = "Detected " + (string)numberDetected + " avatar(s): " + llDetectedName(0);
integer i = 0;
