c# – 播放并等待Animation / Animator完成播放

对于Animation系统：

旧的Unity动画播放系统.除非您仍在使用旧的Unity版本,否则不应在新项目中使用此项.

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

这是新的Unity动画播放系统.这应该在您的新项目而不是Animation API中使用.在性能方面,最好使用Animator.StringToHash并将当前状态与散列数进行比较,而不是比较字符串的IsName函数,因为散列是faster.

假设您有名为Jump,Move和Look的州名.你得到如下所示的哈希值,然后使用该功能进行播放并在下面等待它们：

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");

}

对于专门针对碰撞回调函数(OnTriggerEnter)的特定问题的解决方案,有两种可能的方法：

1.启动协同功能,在触发检测后播放动画：

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");
}

要么

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

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");
    }
}
