I’m a bit stuck… I want to make my spaceship roll to the left and to the right (on the z-axis I think, with the usage of Q and E), sorta like this: Do A Barrel Roll! - YouTube But I don’t really know how to go about this… I tried something with tilting, which doesn’t work at all… plus if you look up and tilt then my spaceship goes ape shit!

using UnityEngine;
using System.Collections;

public class FirstPersonController : MonoBehaviour {
	
	public float movementSpeed;
	public float mouseSensitivity;
	private float upDownSpeed;
	//public float rolling;
	
	//CharacterController cc;
	Rigidbody rb;
	
	void Start() {
		Screen.lockCursor = true;
		//cc = GetComponent<CharacterController>();
		rb = GetComponent<Rigidbody>();
	}//start end
	void FixedUpdate() {
		
		//Rotation
		float rotLeftRight = Input.GetAxis("Mouse X") * mouseSensitivity;
		transform.Rotate(0, rotLeftRight, 0);
		
		float rotUpDown = Input.GetAxis("Mouse Y") * mouseSensitivity;
		transform.Rotate(-rotUpDown, 0, 0);
		
		//Roll //doesn't work right at the moment!
		//transform.Rotate(0,0,Input.GetAxis("Horizontal") * - tilt - transform.eulerAngles.z);
		
		//Movement
		float forwardSpeed = Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime;
		float sideSpeed = Input.GetAxis("Horizontal") * movementSpeed * Time.deltaTime;
		
		//Up and Down
		if(Input.GetKey("space")) {
			upDownSpeed = movementSpeed * Time.deltaTime;
		} else {
			if(Input.GetKey("left ctrl")) {
				upDownSpeed = -movementSpeed * Time.deltaTime;
			} else {
				upDownSpeed = 0.0f;
			}
		}
		                        //(left/right, up/down, forward)
		//Vector3 speed = new Vector3(sideSpeed,0,forwardSpeed);
		Vector3 speed = new Vector3(sideSpeed,upDownSpeed,forwardSpeed);
		
		speed = transform.rotation * speed;
		
		//cc.Move(speed * Time.deltaTime);
		rb.velocity = movementSpeed * speed * Time.deltaTime;
		
	}//update end
}//class end

It shouldn’t be much different than turning left/right or up/down. Line 29 would be something like:

rollLeftRight = Input.GetAxis("Roll") * tilt;
transform.Rotate(0, 0, rollLeftRight);

You are trying to use the current rotation in your commented out code. You didn’t need to do that for the X and Y rotation, therefore you don’t need to for Z rotation .
