How to lock roll axis

Good day, all!

Maybe some can give me some help here, please?

I'm working on flying vehicle controller with physics and I encounter one problem. While using addRelativeTorque to yaw and pitch axes ship also rotating by roll axis at some point.

So here's my simple code:

Code (CSharp):

1.     void LateUpdate()
2.     {
3.         float mouseH = Input.GetAxis("Mouse X");
4.         float mouseV = Input.GetAxis("Mouse Y");
5.         float hRotation = mouseH * rotationSpeed * Time.deltaTime;
6.         float vRotation = mouseV * rotationSpeed * Time.deltaTime;
7.            
8.         if (InvertY == true) {
9.             vRotation = -vRotation;
10.         }  
11.    
12.         m_Rigidbody.AddRelativeTorque(Vector3.up * hRotation);
13.         m_Rigidbody.AddRelativeTorque(Vector3.right * vRotation);

Can I somehow substract Vector3.forward maybe? Or how else can I lock one axis?

Thanks!

 

Okay.. I figured this out. Not sure if it's a right way to do it, but.. If someone will encounter same problem:

Code (CSharp):

1.    
2. public class ShipController : MonoBehaviour
3. {
4.     private float xRot;
5.     private float yRot;
6.  
7. void LateUpdate()
8.     {    
9.         xRot = transform.rotation.eulerAngles.x;
10.         yRot = transform.rotation.eulerAngles.y;
11.      
12.         transform.rotation = Quaternion.Euler(xRot, yRot, 0);
13.  
14.        m_Rigidbody.AddRelativeTorque(Vector3.up * hRotation);
15.        m_Rigidbody.AddRelativeTorque(Vector3.right * vRotation);
16.     }
17. }

And after transform.rotation you can addTorque to x and y axes.
