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;
}
