Description
Event: sensor( integer num_detected ){ ; }| 13 | Event ID |
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.
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
}
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.");
}
}</lsl>
