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 = ; i < atlasLines.Length - ; i++)

            {

                if (atlasLines[i].Length == )

                    _lsPng.Add(atlasLines[i + ]);

            }

            //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 = ; 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[] { atlasAsset };

            skeletonDataAsset.skeletonJSON = jsonFile;

            skeletonDataAsset.fromAnimation = new string[];

            skeletonDataAsset.toAnimation = new string[];

            skeletonDataAsset.duration = new float[];

            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;

        }
