LlSensor

De DigiWiki.

This sensor scans a 45 degree cone about the x-axis. (PI/2 or PI_BY_TWO scans a hemisphere. PI is a spherical scan.)

llSensor( "Gigs Taggart", NULL_KEY, AGENT, 96.0, PI/4 );

This sensor detects all prims and agents with a given name within 15m of the sensor. (AGENT, PASSIVE and ACTIVE behave inclusively. SCRIPTED is not inclusive and will exclude non-scripted targets (like avatars) from the detected set.)

llSensor( "", NULL_KEY, ( AGENT | PASSIVE | ACTIVE ), 15.0, PI );

Sensor pi by four.png arc = PI / 4

Sensor pi by two.png arc = PI / 2

Sensor pi.png arc = PI

Basic example script that when touched executes a sensor scan of agents. When the sensor event is processed it spits out messages to the owner of each detected agents' name.
