How to freeze enemy's movement/rotation during isAttacking state?

Questions & Answers

Hello! I have a script that lets enemy chase the player and setted up an Animator for this enemy with different parameters (isIdle, isMoving and isAttacking). And now I am trying to make enemy stop moving and rotating when isAttacking state is active. Here is the script I have:

using System.Collections;
using UnityEngine;

public class Chase : MonoBehaviour {

	public Transform player;
	static Animator anim;



	// Use this for initialization
	void Start () 
	{
		anim = GetComponent<Animator> ();
	}
	
	// Update is called once per frame
	void Update () 
	{

		if (Vector3.Distance (player.position, this.transform.position) < 3) 
		{
			Vector3 direction = player.position - this.transform.position;
			direction.y = 0;

			this.transform.rotation = Quaternion.Slerp (this.transform.rotation, Quaternion.LookRotation (direction), 0.1f);

			anim.SetBool ("isIdle", false);
			if (direction.magnitude > 1) 
			{
				this.transform.Translate (0, 0, 0.05f);
				anim.SetBool ("isWalking", true);
				anim.SetBool ("isAttacking", false);
			} 
			else 
			{
				anim.SetBool ("isAttacking", true);
				anim.SetBool ("isWalking", false);
				//StartCoroutine(StopMovement(5.0f));
			}
		} 
		else 
		{
			anim.SetBool ("isIdle", true);
			anim.SetBool ("isWalking", false);
			anim.SetBool ("isAttacking", false);
		}

		

	}
}

Firstly I tried to apply this guy’s method (How To Stop Enemy Movement During Its Attack Animation - Questions & Answers - Unity Discussions), when you assign StopMovement function on every animation clip of the character, because our scripts are mostly similar. But for some reason I don’t think that’s how it should be done and it didn’t work for me too (I tried to put Debug.Log(“Stopped moving”); in the part after “if (active == 0)” and during testing it never appeared in console/enemy was still moving/aiming at player during it’s attacks).
Then I tried to add a bool method StopMovement that checks if the isAttacking is true and if it’s true - transform.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezeAll;
The whole method was looking like that:

  public bool StoppingMovement()
	{
		if (isAttacking == true)
		{
			transform.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezeAll;
			return (true);
		}
		else
		{
			return (false);
		}
	}

But because my knowledge of C# is pretty much lacking during my attempts to make it work I was getting different errors like “Cannot implicitly convert type ‘void’ to ‘bool’” or “Method must have a return type” and after spending a whole evening of googling I was never able to make it work. Can
someone please explain how should I create a boolean method, check if “isAttacking” state is “true” right now and, if it is, stop movement/rotating of the enemy?
Thank you very much in advance!

public enum State
{
Inventoried,
Loose,
Still,
Carried
}
public State state;

void Update()
{
	if (state == State.Loose)
	{
		idleTimer++;
		currentPosition = transform.position;
		currentRotation = transform.rotation;
		if (idleTimer >= looseTime) { state = State.Still; }
		if (carrier != null) { state = State.Carried; }
	}

	if (state == State.Still)
	{
		idleTimer = 0;
		transform.SetPositionAndRotation(currentPosition, currentRotation);
		if (carrier != null) { state = State.Carried; }
	}

	if (state == State.Carried)
	{
		if (carrier == null) { state = State.Loose; }
		
		transform.position = carrier.transform.position - (carrier.transform.forward / divDistance) + carryHeight;
		transform.rotation = Quaternion.Euler(objRotation + carrier.transform.rotation.eulerAngles);
	}
}

As you can see, I had the same issue with setting up my objects movement. So I set a states enum for the object, so only when it was in it’s state did it receive any movement, or rotation calls
