"Thanks kaupen i've been wanting to learn minecraft modding for so long and ive been using mcreator, but i love programming and your Forge series is helping alot. Ive gotten better and i am slowly learning the ins and outs of minecraft modding so THANKYOU!"

"Thanks for the tutorials you provided, modding is quite difficult if you don't know what territory you enter. The videos go in detail, usually i use them as sort of a "cheat sheet" to just know what this and that do. But still, the fact this goes in depth is amazing and there are few that commit to this effort. The tutorials also constructed a base for me to get used to Forge more easily. "

FAQ

Got Questions?

Everything you need to know about the Forge 1.20 Course.

No prior experience needed. The courses start from zero — setting up Java, IntelliJ IDEA, and your development environment — and build up step by step. If you can play Minecraft, you can follow along.
NeoForge is the successor to Forge, but they are similar in their style. NeoFroge is the most widely-used modding framework with the biggest ecosystem of mods starting 1.21.1. Fabric is lighter, faster, and updates to new Minecraft versions quicker.
The Forge 1.20 course is ONLY compatible with Minecraft Version 1.20.1. There are no update guides available for this course! If you wish to use any other 1.20.X minor version, I cannot recommend this course to you!
