(UUID) AV vs Object

[Mia Puddles]

is there a way to know if its a AV or object talking. Working on a script that I need to send messages on to other commands based off its a av or object talking? Basically skipping commands on objects sending select commands being I have no reason to run more than one listener.

Avatar UUIDs (mostly) follow RFC-4122 for Version 4 UUIDs - so you can test if a given key is an avatar if the first character in the 3rd block is the number 4.

Example:

a4c8e920-db28-40a7-ab0d-6dc5c178b095 - Mia Puddles

There are some exceptions to this however (I believe older avatar UUIDs do not follow this pattern - pre 2006 (?)):

Another way to test is to pass the key off to a function like llRequestUsername to see if a value is returned (key is an avatar); or if it times out (key is any other asset type).

I recommend llGetAgentSize() for agents and llGetOwnerKey() for objects if the source is in the same region.

Most other functions have edge cases that can yield failures or false negatives.

I.E.

key thing = llDetectedKey(n); // for example.
if(llGetOwnerKey(thing)!=thing)
{ // is an object, and is in same region, (or the key was not a valid key)
  /*
  if(thing)
  { // gratuitous check that thing was actually a valid key, probably unneccessary.
  }else
  { // thing wasn't actually a key, probably a scripting error.
  } */
}else if(llGetAgentSize(thing))
{ // is an avatar, and is in the same region.
}else
{ // is not in the same region.
}

If I'm reading the caveats correctly, then

if(llList2Integer(llGetObjectDetails(thing,[OBJECT_BODY_SHAPE_TYPE]),0)==-1)
{ // (assuming a valid key) thing is an object and may or may not be in the current region.
  // or possibly an avatar shouting from over 34 feet on the other side of the region border.
}
// alternatively 
if(llList2Key(llGetObjectDetails(thing,[OBJECT_CREATOR]),0))
{ // (assuming a valid key) thing is an object and may or may not be in the current region.
  // or possibly an avatar shouting from over 34 feet on the other side of the region border.
}
