How do I create a thumbstick with custom movement

I'm trying to combine these two examples (not to mention the awesome example i got from Cipriux)

Kyatric's Asteroid clone in less than 100 events

and

LittleStain's Thumbstick-template (with capx)

The reason is because in Kyatric's great example it only uses key's for movement, not a thumbstick or touch. And in LittleStain's it doesn't use the custom movement i need for the rocket, like accelerate and rotate.

Even if i only had a round sprite object that used a touch input for the angle, rotate and custom movement would work. I spent all day yesterday trying to combine 3 or 4 different examples/ tutorials but can not replicate the custom movement.

If anyone could help me with this problem, it would be greatly appreciated.
