So I'm standing at the starting line here, wondering where to go.
(mass edit after work done starting HERE)
I've successfully set up a Forge 1.12 SDK for IntelliJ IDEA. Past here though I really have zero idea of where to go. I intend on creating a simple mod to start: a musket kinda like the one from Balkon's Weapons, and a Villager profession to tote it around and shoot at hostile mobs within village limits.
Where should I go to start creating such a mod? Any good tutorials on working with IntelliJ for Minecraft development? If it helps, I have this plugin installed for development.
