Direction Sensor

I think it'd be a great addition to Sackbots if we could have a sensor that detects which direction they are facing. (Left or right)

But... sack people don't face left or right when standing still?

If you wanted something that detected whether they are MOVING left or right, you could use a floating piece of hologram on a rocket rotator that follows the sackbot. Some clever system of key tags could make that work...

Aha, thanks for that...
