Function: llSensor( string name, key id, integer type, float range, float arc );

Performs a single scan for name and id with type within range meters and arc radians of forward vector

• string name Object or avatar name
• key id
• integer type mask (AGENT, ACTIVE, PASSIVE, and/or SCRIPTED)
• float range range 0.0 to 96.0m
• float arc the max angle between the local x-axis of the prim and detectable objects, range 0.0 to PI

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.


  • When searching for an avatar but not by name, it doesn't matter which AGENT flag is used.

This sensor scans a 45 degree cone about the x-axis. <lsl>llSensor( "Gigs Taggart", NULL_KEY, AGENT, 96.0, PI/4 );</lsl>

PI/2 or PI_BY_TWO scans a hemisphere. PI is a spherical scan.
