If you want to try and make a full mod for Minecraft, there are a series of videos that walk you through the process.
This is a more advanced project, before you start you will need these things:
- Your own machine to work on, as it requires installing several pieces of software to get going.
- You will need a Minecraft license to try out your Mod.
The coding is in Java, so, whilst the video tutorials are quite comprehensive, its best if you are reasonably comfortable typing on the computer.
