解决需求

边走路边砍人，边走路边挥手

单层动画播放

  skeletonAnimation.AnimationState.SetAnimation(0, animationName, loop);

多层融合

Unity导入Spine 动画后，在Unity端导出Animation Referance Assets

代码中使用

//Step1: 加载并缓存 AnimationReferenceAsset 文件
 AnimationReferenceAsset asset = LoaderCtrl.Instance.Load<AnimationReferenceAsset>(path) as AnimationReferenceAsset;
            CachedAnimationReferenceAsset.Add(type, asset);
//Step2: 播放的时候使用不同的trackIndex
 CachedSkeletonAnimation.AnimationState.SetAnimation(0, SpineAssetLoaderHelper.GetAnimationReferenceAssetByType(AnimationReferenceType.TankMove), true);
                CachedSkeletonAnimation.AnimationState.SetAnimation(1, SpineAssetLoaderHelper.GetAnimationReferenceAssetByType(AnimationReferenceType.TankAttrack), false);
