Hello, anyone knows how to make a it so that a particle appears (like the one when you use the ronin shovel) but which does damage?

Create a digger, give it FullAuto = 0 and make it's particles invisible.

Simple, eh?

Kind of. (As because i cant even mod correctly...)
Thanks for the answer though!
EDIT: I actually sprited a Pickaxe and made it into the ronins, but it kind of works strange...i think i should look al ittle bit more into it.

Im a bit of a noob, but I would suggest editing the ronin shovel. Edit the 'slash' sprite to whatever you want, and edit the shovel to whatever you want. Then, take out the dig feature, and presto. Melee weapon.

I would definately recommend doing this, as it's the simplest, and there is little possibility for an error. Also, I have tried to mod the Ronin shovel before, and it didn't work too well, as I had great trouble aligning the projectile with the weapon.
