unity3d之控制人物转向移动并播放动画

tip：transition 勾选Has Exit Time B动画播放完毕后就可以自己返回A不用代码控制。因为想做一个小人静止时 隔两秒会摆动小手的特效。

附上代码参考：

 using UnityEngine;
 using System.Collections;

 public class playeMove : MonoBehaviour
 {

     public Animator PlayerAnimator;
     public const int HERO_UP = ;
     public const int HERO_RIGHT = ;
     public const int HERO_DOWN = ;
     public const int HERO_LEFT = ;
     float  FreakTime=;
     //人物当前行走的方向状态
     public int state = ;
     //人物移动速度
     public int moveSpeed =;

     //初始化人物位置
     public void Awake()
     {
         state = HERO_UP;
     }
     // Use this for initialization
     void Start()
     {

     }

     // Update is called once per frame
     void Update()
     {

         //获取控制的方向， 上下左右，
         float KeyVertical = Input.GetAxis("Vertical");
         float KeyHorizontal = Input.GetAxis("Horizontal");
         //Debug.Log("keyVertical" + KeyVertical);
         //Debug.Log("keyHorizontal" + KeyHorizontal);
         if (KeyVertical <)
         {
             setHeroState(HERO_DOWN);
         }
         else if (KeyVertical >)
         {
             setHeroState(HERO_UP);
         }

         if (KeyHorizontal >)
         {
             setHeroState(HERO_RIGHT);
         }
         else if (KeyHorizontal <)
         {
             setHeroState(HERO_LEFT);
         }

         //得到正在播放的动画状态
         AnimatorStateInfo info = PlayerAnimator.GetCurrentAnimatorStateInfo();

         //如果没有按下方向键且状态不为walk时播放走路动画
         if (KeyVertical !=  || KeyHorizontal !=   && !info.IsName("Walk"))
         {
             PlayerAnimator.Play("Walk");
         }
         //否则如果按下方向键且状态为walk时播放静止动画
         else if((KeyVertical ==  && KeyHorizontal ==  && info.IsName("Walk") ))
         {
             PlayerAnimator.Play("Idle");
         }

         //这里设定是玩家静止时隔2s会摆动一次
         if (KeyVertical ==  && KeyHorizontal == )
         {
             //当玩家静止时，FreakTime才会计时
             if (info.IsName("Idle"))
             {
                 FreakTime -= Time.deltaTime;
                 if (FreakTime <= )
                 {
                     Debug.Log(FreakTime);
                     FreakTime = ;
                     //FreakingOut设置为播放后自动退出到idle
                     PlayerAnimator.Play("FreakingOut ");
                 }
             }
         }

     }

     void setHeroState(int newState)
     {
         //根据当前人物方向与上一次备份的方向计算出模型旋转的角度
         int rotateValue = (newState - state) * ;
         Vector3 transformValue = new Vector3();

         //播放行走动画  

         //模型移动的位置数值
         switch (newState)
         {
             case HERO_UP:
                 transformValue = Vector3.forward * Time.deltaTime;
                 break;
             case HERO_DOWN:
                 transformValue = (-Vector3.forward) * Time.deltaTime;
                 break;
             case HERO_LEFT:
                 transformValue = Vector3.left * Time.deltaTime;
                 break;
             case HERO_RIGHT:
                 transformValue = (-Vector3.left) * Time.deltaTime;
                 break;
         }

         transform.Rotate(Vector3.up, rotateValue);
         //移动人物
         transform.Translate(transformValue * moveSpeed, Space.World);
         state = newState;
     }
