# [Animator](Animator.html).GetCurrentAnimatorStateInfo

public [AnimatorStateInfo](AnimatorStateInfo.html) **GetCurrentAnimatorStateInfo** (int **layerIndex**);

## 参数

| layerIndex | 层索引。 |
| ------------ | ---------- |

## 返回

**AnimatorStateInfo** 一个 [AnimatorStateInfo](AnimatorStateInfo.html)，其中包含有关当前状态的信息。

## 描述

返回 [AnimatorStateInfo](AnimatorStateInfo.html)，其中包含有关当前状态的信息。

从动画器中的当前状态获取数据。使用该函数可获取状态的详细信息，包括访问状态的速度、长度、名称和其他变量。要从状态持有的剪辑中收集信息，请参阅 [Animator.GetCurrentAnimatorClipInfo](Animator.GetCurrentAnimatorClipInfo.html)。

```
//Create a GameObject and attach an Animator component (Click the Add Component button in the Inspector window, go to Miscellaneous>Animator).
//Create an Animator by going to Assets >  Create > Animator Controller. Attach this Controller to the Animator attached to your GameObject
//In the Animator Controller, create a Trigger parameter in the Parameters tab and name it “Jump”. Then create states and transition arrows that use this parameter.

//This script triggers an Animation parameter when you press the space key.

using UnityEngine;

public class Example : MonoBehaviour
{
    Animator m_Animator;
    //Use to output current speed of the state to the screen
    float m_CurrentSpeed;

void Start()
    {
        //Get the Animator, which you attach to the GameObject you intend to animate.
        m_Animator = gameObject.GetComponent<Animator>();
        //The current speed of the first Animator state
        m_CurrentSpeed = m_Animator.GetCurrentAnimatorStateInfo(0).speed;
    }

void Update()
    {
        //Press the space bar to tell the Animator to trigger the Jump Animation
        if (Input.GetKeyDown(KeyCode.Space))
        {
            m_Animator.SetTrigger("Jump");
        }

//When entering the Jump state in the Animator, output the message in the console
        if (m_Animator.GetCurrentAnimatorStateInfo(0).IsName("Jump"))
        {
            Debug.Log("Jumping");
        }
    }

void OnGUI()
    {
        //Output the first Animation speed to the screen
        GUI.Label(new Rect(25, 25, 200, 20),  "Speed of State : " + m_CurrentSpeed);
