从不同的AnimationClips和AssetBundle加载预制件

Question

我试图从一个AssetBundle加载Prefab，从另一个AnimationClips加载相应的Prefab。到目前为止，从AssetBundle加载预置文件和实例化都是成功的。

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 (遗产动画)并将其添加到上述实例化的游戏对象中也是成功的。

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);

当我试图播放动画，它不工作，但我没有收到任何错误。

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?该怎么做？

问题是，您试图在预置对象上播放动画，而不是实例化对象：

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，它将返回实例化的对象。返回的对象应该用于获取Animation组件，然后播放您的动画。请注意，您的代码还没有完成，因此可能会出现其他问题，但这个问题也可能导致您的问题。

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>();
