Returns a key that is the UUID of the user seated on the prim.
If the prim lacks a sit target or there is no avatar sitting on the prim, then NULL_KEY is returned.
Caveats
- If the prim lacks a sit target or the avatar is seated upon a different prim, the only way to determine how many and which avatars are seated upon the object is to scan the link set1.
Examples
default { state_entry() { // set sit target, otherwise this will not work llSitTarget(<0.0, 0.0, 0.1>, ZERO_ROTATION); } changed(integer change) { if (change & CHANGED_LINK) { key av = llAvatarOnSitTarget(); if (av) {//evaluated as true if not NULL_KEY or invalid llSay(0, "Hello " + llKey2Name(av) + ", thank you for sitting down"); } } } }
Useful Snippets
//Gets the link number of a seated avatar integer GetAgentLinkNumber(key avatar) { integer linkNum = 1 + llGetNumberOfPrims(); key linkKey; //Next we get the linkKey and make sure it's not null, if it's null we are done. while((linkKey = llGetLinkKey( --linkNum )))//is the key valid? if(avatar == linkKey)//is it the avatar we want? return linkNum;//It's the avatar we want so return. //avatar wasn not found //return a number that isn't a LINK_* flag not a valid link number either. return 0x7FFFFFFF;//max int. }//Written by Strife Onizuka
Notes
- To scan a link set using a function such as llGetLinkKey (see llGetNumberOfPrims#Useful_Snippets for examples).
- The position of an avatar on a sit target can be determined with the use of llGetObjectDetails (see llSitTarget#Useful_Snippets for example).
