Getting the correct movement vector to fire a bullet from a rotated sprite

Hi,

I'm using a SKNode to represent a ship sprite. This sprite can be rotated and moved by touch events. This sprite should fire a bullet (another SKNode object) every second.

I plan to use SKAction to move the bullet.

The zRotation method of SKNode objects returns the rotation around the z-Axis. But how can I transform this into the right vector?

Thanks for your help Stefan
