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.
- A sensor running in an attachment will not detect the avatar wearing it.
Examples
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."); } }
