How to lock movement for a character while attack animation using "while" function?

Question

Hello!

I'm a Unity noob. I have successfully implemented animations for jumping, running and attacking to a character, but I want to disable movement while the attack animation is playing. This is the relevant code I used for the horizontal movement and attack. The solutions I've read haven't really helped me, but I have an idea to accomplish what I want.

I had hoped that a "while" would work, but it doesn't. There's no error, but I would like to know how to implement this idea correctly.

 public float Speed;
  
 private Rigidbody2D Rigidbody2D;
 private Animator Animator;
 private float Horizontal;
  
 private void Start()
     {
         Rigidbody2D = GetComponent<Rigidbody2D>();
         Animator = GetComponent<Animator>();
     }
  
 private void Update()
     {
         Horizontal = Input.GetAxisRaw("Horizontal");
         if (Horizontal < 0.0f) transform.localScale = new Vector3(-1.0f, 1.0f, 1.0f);
         else if (Horizontal > 0.0f) transform.localScale = new Vector3(1.0f, 1.0f, 1.0f);
        
         Animator.SetBool("Run", Horizontal != 0.0f);
        
        
         if (Input.GetKeyDown(KeyCode.F))
            {
                Attack();
            }
        
        //This is the "solution" I tried, but didn't work. It's an analog for .IsPlaying() from the animation component. The "Speed" variable is the one I use to indicate movement. 
        while (Animator.GetCurrentAnimatorStateInfo(0).IsName("CharacterAttack") == true)
           {
               Speed = 0.0f;
           }
     }
  
 private void Attack()
     {
         //The trigger for the animator that kick the attack animation.
         Animator.SetTrigger("Attack");
     }
  
 private void FixedUpdate()
     {
         Rigidbody2D.velocity = new Vector2(Horizontal * Speed, Rigidbody2D.velocity.y);
     }

}

You could wrap your movement code in an IF statement. Declare a bool of canMove and default it to true.

 private void FixedUpdate()
      {
          if(canMove)
          {
              Rigidbody2D.velocity = new Vector2(Horizontal * Speed, Rigidbody2D.velocity.y);
          }
          
      }

Then use a coroutine to handle the logic flow of canMove = Fasle, trigger attack animation and then set canMove back to true again.

Thank you both! Your answers really helped me. For now, I managed to achive this using this code:

 private void Update()
     {
         if(Animator.GetCurrentAnimatorStateInfo(0).IsName("Attack"))
         {
             Speed = 0.0f;
         } else {
             Speed = 3.5f;
         }
