Setting up Virtual Joysticks to move player?

Hi

I've been trying to set up a control system like Geometry Wars for my game and had a lot of problems with travelling and having it face the direction it was travelling in. I was doing this with just the keyboard and it wasn't going all that well so as I was going to have to redo it for Joysticks anyway I thought sod it.

I've never done joysticks before and am pretty crap at it.

I'm using the Dual Joysticks from the Standard Assets but how do I control the player character. Just trying to use the left stick for movement on the X and Z axis and have him face the direction he is travelling in.

I'm trying to replicate this sort of movement. https://www.youtube.com/watch?v=y-_qlaywKBs

Any help or ideas would be fantastic please.
