StateMachineBehaviour状态机行为

StateMachineBehaviour和MonoBehavior一样是一个特殊的类，Monobehavior挂在Gameobject下，而StateMachineBehaviour挂在状态控制器下，用于分割状态控制器行为。

using UnityEngine;

public class AttackBehaviour : StateMachineBehaviour
{
public GameObject particle;
public float radius;
public float power;

protected GameObject clone;

override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
clone = Instantiate(particle, animator.rootPosition, Quaternion.identity) as GameObject;
var rb = clone.GetComponent<Rigidbody>();
rb.AddExplosionForce(power, animator.rootPosition, radius, 3.0f);
}
override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Destroy(clone);
}
override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack Update ");
}
override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack Move ");
}
override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
Debug.Log("On Attack IK ");
}
}

StateMachineBehaviour 的回调函数有: OnStateEnter, OnStateExit, OnStateIK, OnStateMove, OnStateUpdate.把这个脚本挂在状态控制器下，可以很清楚的知道状态控制器在执行什么状态 如图：
