using UnityEngine;
using UnityEditor;

public class IdleBehaviour : StateMachineBehaviour { public int transitionCount; protected int randomTransitionId = Animator.StringToHash("random");

// OnStateEnter is called when a transition starts and the state machine starts to evaluate the state override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { }

// OnStateUpdate is called at each engine tick between OnStateEnter and OnStateExit callback override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { if (stateInfo.normalizedTime > 0.5f) animator.SetInteger(randomTransitionId, Random.Range(0, transitionCount)); }

// OnStateExit is called when a transition ends and the state machine ends to evaluate the state override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { } }
