The Fan item was strangely absent from Smash 4 after appearing in every previous installment of Smash Bros. But I managed to bring it back to its original glory. Unfortunately, I was forced to replace a battering item, so I chose Ore Club which is my least favorite one. After removing the tornado, changing the htiboxes, speeding up the animation, changing item physics parameters, and even adding UI, it is complete. I did not just edit KB and damage amounts.
The contents of the ZIP should go in the patch folder of your Sm4shExplorer workspace.
Oh, you changed the function to match the fan... I did not expect that nor think it was possible, so that's awesome, for real. Although... I was honestly hoping for the fan to blow tornadoes (which would be kinda fitting) and also hit like a truck (which would not be fitting but very funny). Oh well.
I'm glad this finally exists, as even though I can safely say the Fan isn't the least irritating item in Smash history, it's still miles better than the goddamn Ore Club (which hits quite far and packs a strong punch, and adds a projectile ontop of that).
tl;dr: The Fan is actually less broken and more fun to use than the Ore Club, lmao
