cannot have all constraints on in rigidbody?

Questions & Answers
1

I have a script that is meant to have the players, rigidbodies, rotation always locked, and when you click, but only while clicking, the position is frozen, but when I freeze the position it unfreezes rotation, is there a way to solve this?

void Start()
{
    rb.constraints = RigidbodyConstraints.FreezeRotation;
    time = starttime;
    dash = false;
}

 void Update()
 {
    if (Input.GetButtonDown("Fire1"))
    {
        fist1.velocity = (Vector3.forward * speed * punch);
        rb.constraints = RigidbodyConstraints.FreezePosition;      
    }
}

Rigidbody contraints are flags

 void Start()
 {
     rb.constraints = RigidbodyConstraints.FreezeRotation;
     time = starttime;
     dash = false;
 }
  void Update()
  {
     if (Input.GetButtonDown("Fire1"))
     {
         fist1.velocity = (Vector3.forward * speed * punch);
         rb.constraints |= RigidbodyConstraints.FreezePosition; // Freeze position & rotation
     }
     else if (Input.GetButtonUp("Fire1"))
     {
         rb.constraints &= ~RigidbodyConstraints.FreezePosition; // Unfreeze position
     }
 }

Another solution:

 void Start()
 {
     rb.constraints = RigidbodyConstraints.FreezeRotation;
     time = starttime;
     dash = false;
 }
  void Update()
  {
     if (Input.GetButtonDown("Fire1"))
     {
         fist1.velocity = (Vector3.forward * speed * punch);
         rb.constraints = RigidbodyConstraints.FreezeAll;
     }
     else if (Input.GetButtonUp("Fire1"))
     {
         rb.constraints = RigidbodyConstraints.FreezeRotation;
     }
 }
