How to make my custom shears not use durability on blocks it dont shear?

[LilyKat24]

Hello! first of all I'm new to programming and this is my first mod, sop please go "easy" on me :3

I am making a mod that adds more kinds of shears, so far I've added the first shear, and it actually works, but i want to make it so when i break a block that a shear isn't able to "shear", I don't want the durability to go down.

any way i can make this happen? here's the code of my Wooden Shears class, thanks!

 

package me.lilykat24.moarshears.items;

• Code style, issue 2.
• You call damageItem in multiple places. Simply don't call it when you don't want the item to take damage.

Oh! So simple lol, thanks so much!
