What is an Animation Overrider?

I have looked at the Franimation ao script and it doesn't do what I thought it did. I was expecting to be able to give a command and have a particular animation play, but there are only 5 commands on the thing and now of them are /62 play flip em off animation

So I tried to figure out the code, but I'm too new to really understand what I'm looking at.

I THINK what it does is replace the standard animations in SL wih other automatic animations. If I understand whats going on, there are 21 animation states that cover the different ways your avatar can stand walk and fly, and the AO changes them to something else. Is that right?

If so, is there something else that will let me 'flip off' other annoying noobs (besides me)?

Maybe something like a HUD that lists say 20 actions your Avie could take?

Sorry for the dumb question, and yes, I already searched the forum and spent more than an hour (more like 3) trying to figure this out before I asked.

An AO is basically an attachment that sits there, looks at you a lot and says "are you flying? if so, start this animation instead. Are you standing still? If so, start this animation" and so on. So yeah, you're basically right.

If you want to perform specific animations for special purposes, what you want are gestures, really, which are free (there are HUD animation-triggerers as well but if gestures will do the trick, use those). If you go to the Edit menu and then select Gestures you can see the ones you've got, and add new ones. Gestures can have speech, animations and sounds in them, and you can trigger them with a / command e.g. /bow, or using a function key if you assign one.
