LlSensorRepeat

Performs a single scan for name and id with type within range meters and arc radians of forward vector and repeats every rate seconds. It does not perform the first scan until rate seconds have passed.

If name, id, and/or type are empty or 0, they are ignored.
If id is an invalid key or NULL_KEY it is treated as empty.

See: llSensor for an excellent explanation of arc.

• no_sensor will not be triggered unless the script has a sensor event ~ SVC-2409
  • An empty sensor event is enough to satisfy this condition and cause no_sensor to be triggered.
• The repeat of the sensor event is adversely affected by time dilation (lag).
• Sensors placed in attachments will use the direction the avatar is facing as their forward vector. In mouselook, this means that it will be wherever the avatar is looking, while out of mouselook, this means whichever way the avatar is pointing. This does not include where the avatar's head is pointing, or what animation the avatar is doing, just the direction the avatar would move in if you walked forward. This is the case, regardless of where the object is attached.
• When a sensor event is queued, it dequeues all other sensor events in the queue.

                }
            }
            else if (llSubStringIndex(AllAgents+"\n", "\n"+thisAgent+"\n") < 0)
            {
                AllAgents = AllAgents + "\n" + thisAgent;
            }
        }
    }
}

Lag tip: Consider llVolumeDetect as a less resource intensive alternative to llSensorRepeat in many cases.
