Spine用于Timeline(NullReferenceException: Object reference not set to an instance of an object pine.Unity.Editor.AnimationReferenceAssetEditor.OnInspectorGUI ())

报错信息：Spine.Unity.Editor.AnimationReferenceAssetEditor.OnInspectorGUI () (at Assets/Extention/Spine/Editor/spine-unity/Editor/AnimationReferenceAssetEdito

在Spine使用TimeLine 时 右键--> create --> Spine 创建AnimationReferenceAsset 时出现的这样一个错误

解决方案：找到Sine的SkeletonData.asset 文件

在其Inspector窗口找到Create Animation Reference Asset 按钮，用这个方式创建，后续会对Spine动画用于Timeline 写一篇文章
