About this Mod

Copper Networks

A Copper Network with oxidised parts in the process of being deoxidised

This is primarily a power api for my (and other's) mods to be built on top of. It adds a block known as the copper networker that turns any copper blocks that are connected (including all copper variants and things like copper doors but not anything waxed) into a network through which power can be transported. Placing another copper networker on the same network turns it into a storage, storages extend the capacity of a network (0 by default) by 5000 each time. The networker can be crafted with 8 copper blocks surrounding 1 redstone dust and the Network Storage can be crafted with 8 copper ingots surrounding an iron ingot. (Use JEI for recipes, screenshots in gallery.)

This mod was only recently finished and will likely require future optimisations and language translations outside of English. Contributions on the Github would be greatly appreciated.

Please visit the wiki for more information especially if you are considering developing a mod using this power system.

Thank you to those within the Fabric Modding Discord who dealt with my often rambling and poorly phrased questions. Also thank you to ItsMinceraft for taking my rambling and unorganised notes of mod ideas and turning them into a Miro board that is actually readable.
