Initial Setup - MaketendoDev/Forged-Reactor GitHub Wiki
The Forged Reactor Mod focuses on a Minecraft data-pack feature called tags which are used to group up any items, entities, blocks, etc. this mod utilises this to target a group of items for a feature (HUDS, Attacks, you know it!) as it's easier to give it a feature! It also is really useful for addon support too that's good for addon mods and data-packs who want to use our features (:<
To start of with for Data-pack creators and MC Modders (who don't use MCreator) when your inside your data folder you need to create a new folder inside that called "ironman" which you might know as the namespace now inside that folder you need to create another folder called "tags" and in that folder you have to make another folder called "items" (I know it's a lot of folders 🙄) now in the items folder is where you add a .json file to group the item you want to have that feature to be added to it.
A .json file for a tag would look like this:
{ "values": [ "minecraft:iron_chestplate", "minecraft:iron_helmet" ] }
The values is where you put which item you want them to have the feature. If you want more information please look at these 2 links
