用代码场景Spine人物

在使用Spine动画的时候可能会需要用代码创建，所以就小小的研究了一下 

/// <summary>
        /// 加载一个spine的骨骼动画
        /// </summary>
        /// <param name="path"></param>
        /// <returns></returns>
        public static GameObject loadSpineAnim(string path)
        {
            //加载json,atlas文件;
            TextAsset jsonFile = AssetDatabase.LoadAssetAtPath<TextAsset>(@"Assets\" + path + ".json");
            TextAsset atlasFile = AssetDatabase.LoadAssetAtPath<TextAsset>(@"Assets\" + path + ".atlas.txt");

            //解析图片个数;就是材质个数;
            string atlasStr = atlasFile.ToString();
            string[] atlasLines = atlasStr.Split('\n');
            List<string> _lsPng = new List<string>();
            for (int i = 0; i < atlasLines.Length - 1; i++)
            {
                if (atlasLines[i].Length == 0)
                    _lsPng.Add(atlasLines[i + 1]);
            }
            //创建材质;
            Material[] maters = null;
            if (_lsPng != null)
            {
                maters = new Material[_lsPng.Count];
                string pngPath = path.Replace("/", @"\");
                int pos = pngPath.LastIndexOf(@"\");
                pos++;
                pngPath = pngPath.Remove(pos, pngPath.Length - pos);
                for (int i = 0; i < _lsPng.Count; i++)
                {
                    maters[i] = new Material(Shader.Find("Spine/Skeleton"));
                    maters[i].mainTexture = LY.ResLoad.loadImage(pngPath + _lsPng[i]).texture;
                }
            }
            //创建一个atlas;
            AtlasAsset atlasAsset = ScriptableObject.CreateInstance<AtlasAsset>();
            atlasAsset.atlasFile = atlasFile;
            atlasAsset.materials = maters;
            atlasAsset.Reset();

            //创建一个spine插件的动画文件,并初始化数据;
            SkeletonDataAsset skeletonDataAsset = SkeletonDataAsset.CreateInstance<SkeletonDataAsset>();
            skeletonDataAsset.atlasAssets = new AtlasAsset[1] { atlasAsset };
            skeletonDataAsset.skeletonJSON = jsonFile;
            skeletonDataAsset.fromAnimation = new string[0];
            skeletonDataAsset.toAnimation = new string[0];
            skeletonDataAsset.duration = new float[0];
            skeletonDataAsset.scale = 0.01f;            //创建出来动画的渲染大小;
            skeletonDataAsset.Reset();

            //开始创建GameObject;
            GameObject obj = new GameObject(jsonFile.name);
            //加上动画组件;
            SkeletonAnimation skelet = obj.AddComponent<SkeletonAnimation>();
            skelet.skeletonDataAsset = skeletonDataAsset;
            skelet.transform.localPosition = new Vector3(100f, 0f, 0f);
            skelet.transform.localScale = new Vector3(1f, 1f, 1f);
            skelet.Reset();

            return obj;
        }
