Unity计算总动画师完成然后改变场景

Question

我试图从场景中显示退出动画，同时使用 LoadSceneAsync 加载新场景，将场景保留在内存中直到动画结束，然后切换到新场景，如 this question already solved

问题是我有几个动画在层上运行，它们都由同一个触发器触发，现在我所有的动画都是 1 seg 长度，但有些从 0 开始，有些从 0.5 seg 开始

我如何计算完成动画所需的总时间，异步加载新场景，然后等待动画时间完成或新场景的加载完成（需要更长的时间)，最后换个场景？

我正在考虑使用 2 个同时运行的协程并等待最长的完成，但我不确定这是否可以完成（我对 C# 编程很陌生），有什么想法吗？

现在我正在等待 1.6 Seg 的固定时间，因为我的动画在时间上是相等的，但这可能会改变，这是我能想到的唯一方法......

public void GotoScene(string scene)
{
    // Start exit animations and wait
    CanvasAnimation.SetBool("hide", true);
    StartCoroutine(ChangeScene(1.6f, scene));
}

IEnumerator ChangeScene(float time, string goToScene)
{
    //Set the current Scene to be able to unload it later
    Scene currentScene = SceneManager.GetActiveScene();

    // Wait for exit animation to finish
    yield return new WaitForSeconds(time);

    // The Application loads the Scene in the background at the same time as the current Scene.
    AsyncOperation asyncLoad = SceneManager.LoadSceneAsync(goToScene, LoadSceneMode.Additive);

    //Wait until the last operation fully loads to return anything
    while (!asyncLoad.isDone)
    {
        yield return null;
    }

    //Move the GameObject (you attach this in the Inspector) to the newly loaded Scene
    SceneManager.MoveGameObjectToScene(WireRoomObj, SceneManager.GetSceneByName(goToScene));

    //Unload the previous Scene
    SceneManager.UnloadSceneAsync(currentScene);
}

您可能会从AnimatorStateInfo.normalizedTime 检查动画状态，然后在当前动画的 normalizedTime 低于 1 时在协程中等待。例如：

using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class WaitUntilComplete : MonoBehaviour {

    // Use this for initialization
    void Start () {
        StartCoroutine(WaitUntilAllAnimationsCompleted());
    }

    IEnumerator WaitUntilAllAnimationsCompleted() {
        print("waiting started " + Time.time);
        yield return new WaitWhile(() => GetAllAnimationStates().Any(state => state.normalizedTime < 1f));
        print("waiting ended " + Time.time);
    }

    List<AnimatorStateInfo> GetAllAnimationStates() {
        List<AnimatorStateInfo> states = new List<AnimatorStateInfo>();
        var animatorList = GetComponentsInChildren<Animator>();
        foreach (var anim in animatorList) {
            for (int i = 0; i < anim.layerCount; ++i) {
                states.Add(anim.GetCurrentAnimatorStateInfo(i));
            }
        }
        return states;
    }

}
