I am wondering if it might be possible to use an iProp and the "operate" command to trigger an animation for an avatar when the iprop is moved away from the avatar rather than the avatar coming into proximity (action radius) with it.

The idea being to create a walk controller similar to what Muvizu uses by clever AML scripting. If we could move the iProp 1 meter, and have the avatar animate one walk cycle, it might be possible.;)

Edit:
Or, the iProp could have it's pivot behind the avatar, so it's coming into proximity instead.
