I'm sorry for this request but true is that I'm graphic artist more than programmer.
I extracted Spine-Unity 3.7 runtime unitypackage into Unity 2018.3.4f1 project and now I have this error in Unity:
Assets/Spine/spine-unity/Modules/AnimationTools/AnimationTools.cs(215,6): error CS1501: No overload for method
SetFrame' takes4' arguments
I know that this Spine-Unity runtime isn't built for this version of Unity but please exist some easy way how can I fix it please?
