为Animator的 State加入 Behaviour脚本

为Animator的 State加入 Behaviour脚本

用了N年的Unity竟然不知道Animator这个功能。。。。。。。。。。

1. 点选 Animator里需要控制的状态。
2. 在 Inspector 中点击 Add Behaviour 按钮，建立 Animator 状态专用的 Script

例如在某个状态播完之后，关闭该GameObject：

using UnityEngine;public class UIStateClosed : StateMachineBehaviour {override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {animator.gameObject.SetActive(false);}
}

嗯，脚本是挂在动画机中的动画状态上，而不是通常挂在游戏对象上的。可以设置当该动画状态开始时、播放期间、播放结束时要执行的操作。相当实用

官方示例：

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, Position, Quaternion.identity) as GameObject;Rigidbody rb = clone.GetComponent<Rigidbody>();rb.AddExplosionForce(power, Position, 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 ");}
}
