You're welcome.
By the way, the "default animation" used if there are no targets is the same as the Fight animation, which is actually what it always looks like for Stars or Gambler weapons, so it might look weird for some weapons such as Spears and Rods. I don't think I'd be able to simply make Shadow walk forward and/or throw something out into space. Maybe I could've, but it probably would've taken a LOT more work.
I did find another alternative, wherein instead of moving his arms, Shadow simply stands and raises his arms for a brief moment before returning; this is what Edgar does when he tries to use his Tools in this situation. I turned that down in favour of the Fight animation because for stuff like knives and swords, it actually looks kind of natural; he's merely using an overhand throw instead of underhand.
We have EVEN MORE themes now, but some old ones are gone...
