Hello everyone, I was wondering how I would change an existing item's properties for my mod that I plan on making. It is going to make slimeballs throwable and when you throw it, a small slime comes out that will be a companion when fed feathers. So it essentially turns slimeballs into eggs for slimes.. I know its basic and stuff but if anyone could help me, it would be greatly appreaciated. My skype is notthatstrange. thanks!
