So earlier on I watched a tutorial to add an enchantment to a mod. I added one to my mod (Shadow's Bane, that's what I'm calling the enchantment) and I just realized that it does nothing. And by does nothing I mean I haven't programmed a function into it. I was wondering how to do that. For example, how Bane of Arthropods adds more damage against spiders, like that kind of function.

I'm guessing it has something to do with events, but I'm not sure.

Look at the enderio's enchant: https://github.com/SleepyTrousers/EnderIO/blob/master/src/main/java/crazypants/enderio/enchantment/EnchantmentSoulBound.java

Ahh, ok. I knew it involved events somehow. thanks.
