no_sensor

Description

Event: no_sensor( ){ ; }

14	Event ID
	Delay

Result of a call to llSensor or llSensorRepeat.

Caveats

• sensor/no_sensor are not always the best solution:
  • To determine if something is in/out of range is overkill. For this situation use: llGetObjectDetails as you will see in the Useful Snippets section.
  • To determine if an avatar is in the region, try llGetAgentSize

Examples

//List all avatars in range.
default 
{
     on_rez(integer i) 
     {
          llSensor("", "", AGENT_BY_LEGACY_NAME, 96.0, PI);   // Detect any avatars within a 96 metre radius sphere
     }
     sensor(integer number_detected) 
     {
          integer i = 0;
          do 
          {
               llOwnerSay(llDetectedName(i) + " is " + (string) llVecDist(llGetPos(), llDetectedPos(i) ) + "m away.");
          }
          while(++i < number_detected);
     }
     no_sensor() 
     {
          llOwnerSay("No avatars in range.");
     }
}

Useful Snippets

//An alternative solution for find out if a user is not in range
//No sensor is used so the above caveat doesn't apply.

integer InRange(key uuid, float distance)
{
    list data = llGetObjectDetails(uuid, [OBJECT_POS]);
    if(data == [])
        return 0;
    return llVecDist(llList2Vector(data, 0), llGetPos()) <= distance;
}
