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

 1 using UnityEngine;

 3 public class TestAnimator : MonoBehaviour {
 4 
 5     //------------------------------------------外部
 6     public float Move = 0;
 7     public bool IsDying = false;
 8 
 9     //------------------------------------------内部
10     private Animator animator;

12     //常数
13     private int baseLayerIndex;
14     private int idleStateHash;
15     private int runStateHash;
16     private int dyingStateHash;
17     private string movePara;
18     private string isDyingPara;
19 
20     void Start ()
21     {
22         animator = GetComponent<Animator>();
23 
24         baseLayerIndex = animator.GetLayerIndex("Base Layer");
25         idleStateHash = Animator.StringToHash("Base Layer.Idle");
26         runStateHash = Animator.StringToHash("Base Layer.Run");
27         dyingStateHash = Animator.StringToHash("Base Layer.Dying");
28         movePara = "move";
29         isDyingPara = "isDying";
30     }
31     
32     void Update ()
33     {
34         //------------------------------------------播放动作
35         animator.SetFloat(movePara, Move);
36         if (IsDying)
37         {
38             animator.SetBool(isDyingPara, true);
39             IsDying = false;
40         }
41 
42         //------------------------------------------动作恢复
43         AnimatorStateInfo stateInfo;
44         int fullPathHash;
45 
46         //BaseLayer
47         stateInfo = animator.GetCurrentAnimatorStateInfo(baseLayerIndex);
48         if (!animator.IsInTransition(baseLayerIndex) && stateInfo.normalizedTime >= 1)
49         {
50             fullPathHash = stateInfo.fullPathHash;
51             if (fullPathHash == dyingStateHash)
52             {
53                 animator.SetBool(isDyingPara, false);
54             }
55         }
56     }
57 
58     public void SetDying(bool state)
59     {
60         if (animator)
61         {
62             animator.SetBool(isDyingPara, state);
63         }
64     }
65 }

NewBehaviourScript.cs

 1 using UnityEngine;
 2 
 3 public class NewBehaviourScript : MonoBehaviour {
 4 
 5     public TestAnimator testAnimator;
 6         
 7     void Update ()
 8     {
 9         if (Input.GetKey(KeyCode.Q))
10         {
11             testAnimator.Move = 1;
12         }
13         if (Input.GetKeyUp(KeyCode.Q))
14         {
15             testAnimator.Move = 0;
16         }
17         if (Input.GetKeyDown(KeyCode.W))
18         {
19             testAnimator.IsDying = true;
20         }
21         if (Input.GetKeyDown(KeyCode.E))
22         {
23             testAnimator.SetDying(false);
24         }
25     }
26 }

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
