Summary

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

Performs a single scan for name and id with type (AGENT, ACTIVE, PASSIVE, and/or SCRIPTED) within range meters and arc radians of forward vector (name, id, and/or keytype can be empty or 0)

• string name
• key id
• integer type
• float range
• float arc
Flag Mask Description (llDetectedType()) Description (llSensor() and llSensorRepeat() mask)
AGENT_BY_LEGACY_NAME 0x1 Agents This is used to find agents by legacy name.
AGENT 0x1 Agents This is also used to find agents by legacy name, and is functionally identical to AGENT_BY_LEGACY_NAME
AGENT_BY_USERNAME 0x10 Reserved This is used to find agents by username.
ACTIVE 0x2 Physical tasks. (Physical objects & agents) Physical objects that are moving or objects containing an active script. Thus, it is using SL server resources now.
PASSIVE 0x4 Non-physical objects. Non-scripted or script is inactive and non-physical or, if physical, not moving. Thus, it is not using SL server resources now.
SCRIPTED 0x8 Objects containing any active script. Objects that has any script, which is doing anything in simulator just now.
llDetectedType() Scripted Not Scripted Agent Standing Agent Sitting
Physical Movement 10 (ACTIVE|SCRIPTED) 2 (ACTIVE) 3 (ACTIVE|AGENT) 3 (ACTIVE|AGENT)
Non-Physical 12 (PASSIVE|SCRIPTED) 4 (PASSIVE) 1 (AGENT) 5 (PASSIVE|AGENT)

Examples

This sensor scans a 45 degree cone about the x-axis.

llSensor( "Gigs Taggart", NULL_KEY, AGENT, 96.0, PI/4 );
PI/2 or PI_BY_TWO constant is 90 degrees, aka a hemisphere. PI is a spherical scan.
