Hey guys, it's been a while since I've modded minecraft and I want to get back into it as a hobby. I was wondering how I'd go about overwriting minecrafts vanilla settings on armour and tools. Basically, add some armour bars/health bars, add new tool levels and change the stats on the pre existing sets to tools and armor. My answer might be answered by looking at the libraries but I can't access my workspace at the moment so if anyone knows off the top of their head, that'd be awesome.
This could be a crazy easy thing to do but it'd be great if anyone could help, thanks!
