通过代码动态加载Spine动画资源文件(AB包格式)

    /// 通过代码动态加载Spine动画资源文件(AB包格式)-AB包主要用于热更新下载，这里是把解压缩zip后的文件放在了对应的位置
    /// </summary>
    /// <param name="path">路径名</param>
    /// <param name="dataAssetName">动画名，例如dankuang_SkeletonData这种名字</param>
    /// <param name="transform">通过transform，控制动画的位置</param>
    SkeletonGraphic LoadSpineAnimationFromABPackage(string path, string dataAssetName, Transform transform)
    {
        //通过AB包获得bundle
        AssetBundle bundle = AssetBundle.LoadFromFile(path, 0);
        if (bundle != null)
        {
            Material material = Resources.Load<Material>("Spine/SkeletonGraphicDefault");
            //通过bundle获得SkeletonDataAsset。
            SkeletonDataAsset mySkeletonDataAsset = bundle.LoadAsset<SkeletonDataAsset>(dataAssetName);
            //当参数为false时，会释放掉assetbundle里面的关于资源的压缩文件数据。
            //当参数为true时，该bundle中加载的物体也将被销毁，如果场景中有物体引用该资源，引用会丢失。
            bundle.Unload(false);
            SkeletonGraphic myAnimation = SkeletonGraphic.NewSkeletonGraphicGameObject(mySkeletonDataAsset, transform, material);
            //设置锚点
            myAnimation.GetComponent<RectTransform>().anchoredPosition = new Vector2(0, 0);
            //设置名字
            myAnimation.name = myAnimation.skeletonDataAsset.name;
            //设置材质
            myAnimation.material = material;
            //设置层级
            myAnimation.transform.SetAsLastSibling();
            //将动画尺寸赋给myAnimation
            myAnimation.MatchRectTransformWithBounds();
            //通过射线控制是否可点击
            myAnimation.raycastTarget = false;

mySkeletonGraphic2 = LoadSpineAnimationFromABPackage(Path() + "/Resources/Animation/iOS/spine.test", "test_SkeletonData", transform);
