Alternative to start attacks walking

[James_Bate]

I used to start the attackers walking
on the lizard script .

private void OnTriggerExit2D(Collider2D other)
{
    Debug.Log("no hit");
    GetComponent<attacker>().NotAttacking();
}

attacker script

public void NotAttacking ()
{
    GetComponent<Animator>().SetBool("IsAttacking", false);
}
