NanAO is a compact Animation Overrider (AO) replacement HUD. It loads AO notecards designed for the ZHAO-II, Vista, and Oracul (Kuso) systems, and caches them in a compact LinksetData storage format for instant switching. NanAO can store dozens of AOs this way, all from a single HUD attachment with a tiny script footprint. Additionally, NanAO supports integrations with OpenCollar (and derivatives), and with other Nanite Systems products like the Companion and ARES robot operating systems.

Basic Usage

To install a new AO:

Rez NanAO on the ground.
Make a new folder in your SL inventory named after the AO.
Copy the notecard and animations from your old AO HUD into this folder. Some AOs (especially Oracul) will have multiple notecards; you probably only want one.
Rename the notecard to something terse. It must begin with "ao_" and should have no spaces in it. For example, if you have an AO named "VISTA ANIMATIONS *HUD 5.32*MIRIAM BENTO AO-V.3", then you should just rename the notecard to "ao_miriam".
Select all of the animations and the notecard in your inventory, then (while holding the Ctrl key) drag them into NanAO. You may need to do this in chunks; SL will have difficulties if you move more than 40 or so items at once.
Repeat steps 2-5 as many times as necessary. If your NanAO has many files inside it already, you should Edit it and switch to the "Contents" tab so you can see when SL is done refreshing its inventory after each copy operation.
Pick your NanAO HUD back up. It will appear in your inventory as a new copy, probably without Modify or Transfer permissions. (This is to be expected.)
If you are using Firestorm, you can right-click on your old AO HUDs and choose "Replace Links" to update your outfits.

To switch AOs, click the HUD, then the "select AO" button.

Advanced Usage

(Requires an NS robot controller)

Try the command '@kinematics <name>' (without the 'ao_' prefix) to switch profiles on the fly. You could even put kinematics commands (without the @) in persona and action scripts for your users' convenience!
The command '@kinematics uncache ao_<name>' can be used to forget about a deleted AO and free up memory.
The command '@kinematics uncache all' will forget all cached AOs.
The command '@kinematics list' will list which AOs have been cached.
The command '@kinematics' will list all available AOs.
The command '@kinematics cycle' will switch to a new, randomly-selected animation for the current locomotion pattern.
The command '@kinematics cycle <time>' will set automatic animation cycling to occur every <name> seconds (0 = off)
The command '@kinematics cleanup all' will delete any animations that aren't referenced by a cached notecard. This takes a LONG time to complete. (Do this if a manufacturer may have shared animations between multiple AOs that you've loaded, or accidentally included unused animations.) Make sure you've activated each of your AOs at least once, first, or their animations will be pruned.

Notes

If you are authoring a custom AO, NanAO will attempt to re-load the file when it detects that the UUID has changed.
When removing files, you may see a few script errors about missing animations or notecards (either things you've just deleted or things with no names.) Don't Panic! These are harmless and won't occur during normal usage.
The AO HUD will use the quaternary color (aka color #4 or color D) if available, to match the ARES look and feel.

Update History

2024-03-12 - 9.0.4: Implemented llGetNotecardLineSync(). Now AOs are cached in less than a second. Also added support for HW-CAPS device discovery protocol.
2023-11-09 - 9.0.2: Fixed error messages when cycling is enabled but sits aren't.
2023-11-09 - 9.0.1: Added basic controls for triggering animation cycling. NanAO will also default to assuming you are powered on when attached, so it won't be useless if you attach it to a non-robot avatar after it's been worn with a robot avatar.
2023-11-01 - 9.0: Initial release.
