ACTIVE

Description

Constant: integer ACTIVE = 0x2;

The integer constant ACTIVE has the value 0x2

If it is contained in the result of llDetectedType(), it means it is physical tasks. (Physical objects & agents)
If it is used as an filter of llSensor() or llSensorRepeat(), it will search for physical objects that are moving or objects containing an active script. Thus, it is using SL server resources now.

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

Using llDetectedType in collision event:

integer type;
 
default
{
    state_entry()
    {
        llVolumeDetect(TRUE);
    }
    collision_start(integer detected)
    {
        type = llDetectedType(0);
        if (type == AGENT)// = 1
        {
            llSay(0, "This is impossible. Since there is no avatar who doesn't require the physical calculation.");
        }
        else if (type == ACTIVE)// = 2
        {
            llSay(0, "I have been struck by a physical object not containing any script.");
        }
        else if (type == PASSIVE)// = 4
        {
            llSay(0, "This is impossible. Non-physical objects cannot trigger this event.");
        }
        else if (type == SCRIPTED)// = 8
        {
            llSay(0, "This is impossible. Since there is no object which isn't physical nor non-physical.");
        }
        else if (type == (AGENT | ACTIVE) ) // 1 + 2
        {
            llSay(0, "I have been struck by an avatar.");
        }
        else if (type == (SCRIPTED | ACTIVE) ) // = 8 + 2
        {
            llSay(0, "I have been struck by a physical object containing any script.");
        }
        else if (type == (SCRIPTED | PASSIVE) ) // = 8 + 4
        {
            llSay(0, "This is impossible. Non-physical objects cannot trigger this event.");
        }
    }
}

Using llDetectedType in sensor event:

default
{
    touch_start(integer numberDetected)
    {
         llSensor("", "", ACTIVE | PASSIVE | AGENT, 20.0, PI); // activates the sensor.
    }
 
    sensor (integer numberDetected)
    {
        integer i;
        while(i < numberDetected)
        {
            integer type = llDetectedType(i);
            string message;
            message += (string)i + ", " + llDetectedName(i) + ", ";
            list typeList;
            if (type & AGENT)
            {
                typeList += "AGENT";
            }
            if (type & ACTIVE)
            {
                typeList += "ACTIVE";
            }
            if (type & PASSIVE)
            {
                typeList += "PASSIVE";
            }
            if (type & SCRIPTED)
            {
                typeList += "SCRIPTED";
            }
            message += llDumpList2String(typeList, "|");
            llWhisper(0, message);
            ++i;
        }
    }
 
    no_sensor()
    {
        // This is impossible if range = 20.0 and you are standing within 10m!
        llWhisper(0, "Nothing is near me at present."); 
    }
}

Using filter in llSensor* functions:

// Report nearby sensed objects and avatars under sundry categories
 
list     SenseTypes;
integer  gIndex;
 
SenseNextType()
{
    string  text = llList2String( SenseTypes, gIndex);
    integer tipe = llList2Integer(SenseTypes, gIndex + 1);
    if (tipe)
    {
        llWhisper(0, text);
        llSensor("", NULL_KEY, tipe, 20.0, PI);
        gIndex += 2;   // increment by stride
    }
    else
        llWhisper(0, "--- Finished ---");
}
 
default
{
    touch_start(integer detected)
    {
        // Make a Strided list of text and sensor type combinations
        // (Can't use '|' in Global, unfortunately)
        SenseTypes = [
            "AGENT_BY_LEGACY_NAME", AGENT_BY_LEGACY_NAME,
            "ACTIVE", ACTIVE,
            "AGENT_BY_LEGACY_NAME|ACTIVE", AGENT_BY_LEGACY_NAME|ACTIVE,
            "PASSIVE", PASSIVE,

            "", 0 ];
        gIndex = 0;
        SenseNextType();        // Kick off the sensing sequence
    }
    sensor(integer detected)
    {
        integer x;
        while (x < detected)
