Question

我正在尝试从一个AssetBundle中加载Prefab，并从另一个中加载其对应的AnimationClip。到目前为止，从AssetBundle和Instantiate加载Prefab成功。

AssetBundle assetBundle = AssetBundle.LoadFromFile(path);
if (assetBundle == null) {
     return;
}

GameObject prefab = assetBundle.LoadAsset<GameObject>(name);
Instantiate(prefab, targetTransform.position, targetTransform.rotation);
assetBundle.Unload(false);

加载AnimationClips（旧版动画）并将其添加到上面实例化的Gameobject中也成功。

AssetBundle assetBundle = AssetBundle.LoadFromFile(path);
if (assetBundle == null) {
     return;
}

List<AnimationClip> animationClips = new List<AnimationClip>();
foreach (string name in names) {
     AnimationClip animationClip = assetBundle.LoadAsset<AnimationClip>(name);
     if (animationClip != null) {
        animationClips.Add(animationClip);
     }
}
assetBundle.Unload(false);

当我尝试播放动画时，它不起作用，但是没有出现任何错误。

Animation animation = prefab.GetComponent<Animation>();

foreach (AnimationClip animationClip in animationClips) {
      string clipName = animationClip.name;
      animation.AddClip(animationClip, clipName);
}
foreach (AnimationClip animationClip in animationClips) {
      string clipName = animationClip.name;
      animation.PlayQueued(clipName, QueueMode.CompleteOthers);
}

我错过了什么吗？应该怎么做？

问题是您正在尝试在预制而不是实例化的对象上播放动画：

GameObject prefab = assetBundle.LoadAsset<GameObject>(name);
//You instantiated object but did nothing with it. What's the point of the instantiation?
Instantiate(prefab, targetTransform.position, targetTransform.rotation);
//Don't do this. The Animation is attached to the prefab
Animation animation = prefab.GetComponent<Animation>();

调用Instantiate函数时，它将返回实例化的Object。返回的对象是您用来获取Animation组件然后播放动画的对象。请注意，您的代码不完整，因此可能还有其他问题，但这也可能导致您遇到问题。

GameObject prefab = assetBundle.LoadAsset<GameObject>(name);
//Instantiate the prefab the return the instantiated object
GameObject obj = Instantiate(prefab, targetTransform.position, targetTransform.rotation);
//Get the Animation component from the instantiated prefab
Animation animation = obj.GetComponent<Animation>();

现在，您可以播放它了。

从不同的AssetBundle加载Prefab和AnimationClip
