- Material Stats and their reference:
- You can simply add a new Key to the Material.json and reference them like this
"armor_pen": "[material.hardness]*2.0 + 20", within the module.json - for Examples one can always check the arsenal, archery and armory repositories
- usable gui apis and default extendable Crafter gui

FAQ:
- What Launcher is this for? Forge? Fabric?
- Both, check the jars
- Backport to older versions?
- is not planned. There are many features in Truly Modular which have a significantly higher priority than backporting. Once the list of ideas is smaller we might consider backporting.
- is X mod supported?
- probably? Generative Compatiblity has a high chance of working with most mods out of the box. You can check here for more informations or to report issues
- Can i write a Addon for this?
- Can i use this in a Modpack?
- yes
