欠下的技术债总归是要还的

起因

当初为了实现一个当动画执行结束后，维护一个变量值的功能，在需要维护的状态下动画的最后一帧每一个后面增加一个Event，调用脚本，今天突然发现StateMachineBehaviors功能，之前的处理方式真是抠脚…

Unity官方例子写的非常清楚，之前的需求只需要写在OnStateExit函数中即可…

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;
        Rigidbody 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 ");
    }
}
