is there an onSit event handler or something?

basically i want to change the state when someone 'sits' on the object. but i'm not at all sure how to do that. i was modifying an existing code, and i was able to achieve the effect i needed to by using the changed() event handler, but it had a problem or two. anyway, i can post the code if you need it, but i don't think it's especially relevant to my question.

You can use CHANGED_LINK to determine sit, in combination with llAvatarOnSitTarget()!=NULL_KEY.

there is an example about half way down on this wiki page

Oh, cool, thanks. that did the trick.

one other quesiton, though. what does llResetScript() do exactly?

It resets the script to the original state and memory status it had when you clicked "save" and it compiled. See the wiki for more.
