Made it possible to in a smooth motion tilt the ship 90 degrees to either side using L and R.
A camera now follows the ship from a slight distance.
Still just flying in a straight line through empty space.
Had some troubles implementing the tilt. At first the camera node was attached to the character node which caused the entire thing to rotate, including the camera. Added a small script to the camera to set it to not rotate but instead the began rotating strangely, following the trajectory of a circle. Turned out it was because when i wanted to rotate the ship, instead the entire node including the camera and the space between the ship and the camera rotated. Now, with the camera following as a separate node, the ship tilts as intended!
