same problem for demon slayer mod. i tried to add efm animations to the entities and it works, only problem now is that the mobs attack anything , even for the same entity type. i need help with this.

Datapack entity in 1.18.2 supports the more advanced functionality that you mentioned but seems like demon slayer doesn't port the 1.18.2 version yet.

is there a workaround for this issue?

As far as now, no.

oh ok, thanks for the info. i hope you can fix it soon.
