        public bool  fastBreath;
        // OnStateUpdate is called at each Update frame between OnStateEnter and OnStateExit callback
        override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
            animator.SetBool("FastBreath", fastBreath);
        }
    }
    public class RunBehaviour : StateMachineBehaviour {
        // OnStateUpdate is called at each Update frame between OnStateEnter and OnStateExit callback
        override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) 
        {
            BreathBehaviour[] breathBehaviours = animator.GetBehaviours<BreathBehaviour>();
            for(int i=0;i<breathBehaviours.Length();i++)
