Feel free to try out the Arsenal Network's Tech & Magic modpack which has an official server.
You can download the modpack on technic or atlauncher.
(This is just an updated version of AnimationAPI for those who want to use these animations for their 1.12.2 mods.)
The AnimationAPI is a utility for modders that allows them to create animations for entities more easily. The forum link can be found here for more information, and the modding tutorial can be found on the wiki.
