上一篇是直接通过界面来控制动作的播放，这篇将使用脚本去管理对象的动作

API解析：

Animator.IsInTransition：是否处于过渡状态

状态机如下：

脚本如下：

TestAnimator.cs

 using UnityEngine;

 public class TestAnimator : MonoBehaviour {

     //------------------------------------------外部
     public float Move = ;
     public bool IsDying = false;

     //------------------------------------------内部
     private Animator animator;

     //常数
     private int baseLayerIndex;
     private int idleStateHash;
     private int runStateHash;
     private int dyingStateHash;
     private string movePara;
     private string isDyingPara;

     void Start ()
     {
         animator = GetComponent<Animator>();

         baseLayerIndex = animator.GetLayerIndex("Base Layer");
         idleStateHash = Animator.StringToHash("Base Layer.Idle");
         runStateHash = Animator.StringToHash("Base Layer.Run");
         dyingStateHash = Animator.StringToHash("Base Layer.Dying");
         movePara = "move";
         isDyingPara = "isDying";
     }

     void Update ()
     {
         //------------------------------------------播放动作
         animator.SetFloat(movePara, Move);
         if (IsDying)
         {
             animator.SetBool(isDyingPara, true);
             IsDying = false;
         }

         //------------------------------------------动作恢复
         AnimatorStateInfo stateInfo;
         int fullPathHash;

         //BaseLayer
         stateInfo = animator.GetCurrentAnimatorStateInfo(baseLayerIndex);
         if (!animator.IsInTransition(baseLayerIndex) && stateInfo.normalizedTime >= )
         {
             fullPathHash = stateInfo.fullPathHash;
             if (fullPathHash == dyingStateHash)
             {
                 animator.SetBool(isDyingPara, false);
             }
         }
     }

     public void SetDying(bool state)
     {
         if (animator)
         {
             animator.SetBool(isDyingPara, state);
         }
     }
 }

NewBehaviourScript.cs

 using UnityEngine;

 public class NewBehaviourScript : MonoBehaviour {

     public TestAnimator testAnimator;

     void Update ()
     {
         if (Input.GetKey(KeyCode.Q))
         {
             testAnimator.Move = ;
         }
         if (Input.GetKeyUp(KeyCode.Q))
         {
             testAnimator.Move = ;
         }
         if (Input.GetKeyDown(KeyCode.W))
         {
             testAnimator.IsDying = true;
         }
         if (Input.GetKeyDown(KeyCode.E))
         {
             testAnimator.SetDying(false);
         }
     }
 }

按住Q，播放跑步动画；松开Q，播放站立动画；按下W，播放倒地动画；按下E，播放倒地恢复成站立的动画
