Summary

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 or id is empty then that empty constraint is ignored.
If id is an invalid key or NULL_KEY it is treated as empty.

Caveats

  • When searching for an avatar but not by name, it doesn't matter which AGENT flag is used.
  • Attachments cannot not detect their wearer (this includes HUD attachments).
  • If type is zero, the sensor will silently fail, neither sensor or no_sensor will be triggered.

Examples

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.
