Weapon Attack Animation

[Replitz]

Hiya, I was looking for some help with creating new attack animations for a custom melee weapon in Spriter. Specifically, I'm looking to replicate the Tail o' Three Cats attack animations with a custom weapon. Normally, I find solutions to basic questions like this by scouring the forums, but I could only find info on new character animations or things far too vague to actually help me.

Right now, all I have is the Tail o' Three Cats assets (swap and idle), its code from the base game, and a whole lot of failed attempts. 

I would love to have an actual breakdown of steps for creating the attack animation in Spriter, where to put it and name it, and then how I'm supposed to reference it in the prefab code. And in case anyone wants to look at it what I'm asking for, Tail o' Three Cats referenced as "whip" in the base game.

Thanks for the help!
