How to disable axis rotation?

Question

C++ / C#

I have an object whose rotation along the z axis I need to allow from time to time, I can’t figure out how to correctly refer to the Rigidbody in the script in order to change this parameter.

To make it easier to understand, I will give an example of changing the Is Kinematic parameter through a script . Something like this, is it possible to do the same with rotation lock?

GetComponent<Rigidbody>().IsKinematic = true;

Answer 1

Rigidbody rb;

void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

//запретить
rb.constraints = RigidbodyConstraints.FreezeRotationZ

//разрешить
rb.constraints = RigidbodyConstraints.None;
