播放并等待 Animation/Animator 完成播放 [英] Play and wait for Animation/Animator to finish playing

问题描述

在我的脚本中，当玩家位于平台顶部时，我将其向上移动.它工作正常.但是现在我想在它起床后播放剪辑Down".

In my script i did that when the player is on the top of the platform move it up. It's working fine. But now i want to make that once it got up play the clip "Down".

using UnityEngine;
using System.Collections;
using System.Reflection;

public class DetectPlayer : MonoBehaviour {

    GameObject target;

    public void ClearLog()
    {
        var assembly = Assembly.GetAssembly(typeof(UnityEditor.ActiveEditorTracker));
        var type = assembly.GetType("UnityEditorInternal.LogEntries");
        var method = type.GetMethod("Clear");
        method.Invoke(new object(), null);
    }

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.name == "Platform")
        {
            Debug.Log("Touching Platform");
        }

    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.name == "OnTop Detector")
        {
            Debug.Log("On Top of Platform");
            GameObject findGo = GameObject.Find("ThirdPersonController");
            GameObject findGo1 = GameObject.Find("Elevator");
            findGo.transform.parent = findGo1.transform;
            target = GameObject.Find("Elevator");
            target.GetComponent<Animation>().Play("Up");
        }
    }
}

行后

target.GetComponent<Animation>().Play("Up");

我想在它播放完后把它放低:

I want when it finish playing it play the down:

target.GetComponent<Animation>().Play("Down");

推荐答案

虽然这两个答案都应该有效，但使用协程和 IsPlaying 函数执行此操作的另一种方法.如果您还想在动画后执行其他任务，则使用协程解决方案.

While both answers should work, another method of doing this with coroutine and the IsPlaying function. You use the coroutine solution if you also want to perform other task after the animation.

对于动画系统:

旧的 Unity 动画播放系统.这应该不用于您的新项目，除非您仍在使用旧的 Unity 版本.

The old Unity animation playback system. This should not be used in your new Project unless you are still using old Unity version.

IEnumerator playAndWaitForAnim(GameObject target, string clipName)
{
    Animation anim = target.GetComponent<Animation>();
    anim.Play(clipName);

    //Wait until Animation is done Playing
    while (anim.IsPlaying(clipName))
    {
        yield return null;
    }

    //Done playing. Do something below!
    Debug.Log("Done Playing");
}

对于 Animator 系统强>

这是新的 Unity 动画播放系统.这应该在您的新项目中使用，而不是Animation API.在性能方面，最好使用 Animator.StringToHash 并通过哈希数比较当前状态而不是 IsName 函数比较字符串，因为哈希值更快.

This is the new Unity animation playback system. This should be used in your new Project instead of the Animation API. In terms of performance, it's better to use the Animator.StringToHash and compare the current state by hash number instead of the IsName function which compares string since the hash is faster.

假设您有名为 Jump、Move 和 Look 的状态名称.你得到他们的散列如下，然后使用下面的函数播放和等待他们:

Let's say that you have state names called Jump, Move and Look. You get their hashes as below then use the function for playing and waiting for them them below:

const string animBaseLayer = "Base Layer";
int jumpAnimHash = Animator.StringToHash(animBaseLayer + ".Jump");
int moveAnimHash = Animator.StringToHash(animBaseLayer + ".Move");
int lookAnimHash = Animator.StringToHash(animBaseLayer + ".Look");

public IEnumerator PlayAndWaitForAnim(Animator targetAnim, string stateName)
{
    //Get hash of animation
    int animHash = 0;
    if (stateName == "Jump")
        animHash = jumpAnimHash;
    else if (stateName == "Move")
        animHash = moveAnimHash;
    else if (stateName == "Look")
        animHash = lookAnimHash;

    //targetAnim.Play(stateName);
    targetAnim.CrossFadeInFixedTime(stateName, 0.6f);

    //Wait until we enter the current state
    while (targetAnim.GetCurrentAnimatorStateInfo(0).fullPathHash != animHash)
    {
        yield return null;
    }

    float counter = 0;
    float waitTime = targetAnim.GetCurrentAnimatorStateInfo(0).length;

    //Now, Wait until the current state is done playing
    while (counter < (waitTime))
    {
        counter += Time.deltaTime;
        yield return null;
    }

    //Done playing. Do something below!
    Debug.Log("Done Playing");

}

对于专门针对您的碰撞回调函数 (OnTriggerEnter) 特定问题的解决方案，有两种可能的方法来做到这一点:

---

---

For a solution specifically for your particular problem with the collision callback function (OnTriggerEnter), there are two possible ways to do that:

1.触发检测后启动协程函数播放动画:

1.Start a coroutine function to play the animation after trigger detection:

void OnTriggerEnter(Collider other)
{
    if (other.gameObject.name == "OnTop Detector")
    {
        Debug.Log("On Top of Platform");
        GameObject findGo = GameObject.Find("ThirdPersonController");
        GameObject findGo1 = GameObject.Find("Elevator");
        findGo.transform.parent = findGo1.transform;
        target = GameObject.Find("Elevator");
        StartCoroutine(playAnim(target));
    }
}

IEnumerator playAnim(GameObject target)
{
    Animation anim = target.GetComponent<Animation>();
    anim.Play("Up");

    //Wait until Up is done Playing the play down
    while (anim.IsPlaying("Up"))
    {
        yield return null;
    }

    //Now Play Down
    anim.Play("Down");
}

或

2.使 OnTriggerEnter 函数成为协程(IEnumerator)而不是 void 函数:

2.Make the OnTriggerEnter function a coroutine(IEnumerator) instead of void function:

IEnumerator OnTriggerEnter(Collider other)
{
    if (other.gameObject.name == "OnTop Detector")
    {
        Debug.Log("On Top of Platform");
        GameObject findGo = GameObject.Find("ThirdPersonController");
        GameObject findGo1 = GameObject.Find("Elevator");
        findGo.transform.parent = findGo1.transform;
        target = GameObject.Find("Elevator");
        Animation anim = target.GetComponent<Animation>();
        anim.Play("Up");

        //Wait until Up is done Playing the play down
        while (anim.IsPlaying("Up"))
        {
            yield return null;
        }

        //Now Play Down
        anim.Play("Down");
    }
}
