Ever thought copper was useless? This mod fixes that! Just like in real life, this mod adds both copper and bronze tools, weapons, and armor. It also adds redstone components, including copper wire and logic gates.

Copper Equipment

This mod allows you to craft copper tools, weapons, and armor out of copper ingots, just like you would with stone, iron, etc. This is required for progression, because you'll need copper tools to mine iron! Copper (and bronze) armor is compatible with vanilla armor trims.

If you want to expand progression even further, I recommend installing TNT's Steel, which adds steel tools, weapons and armor to the game!

Oxidation

Just like copper blocks, copper equipment will oxidize over time. You can change how often the check runs and what the chances of oxidizing are in the config file. This will not be affected by tick speed.

You can stop oxidation by throwing the item onto the ground and throwing a honeycomb ontop of it. This will use the honeycomb and show a tooltop on the item saying it's waxed. To remove the wax, throw the item back on the ground and throw an axe ontop of it. This will use the axe's durability.

Due to game limitations, unwaxed copper equipment placed in a container will not oxidize until it's removed, at which point it will oxidize based on how long it was in the container.

Bronze

Bronze Equipment

This mod adds bronze as an optional tier between copper and iron. Crafting bronze equipment is more difficult than copper. Like netherite, you'll need to use a smithing table. Steps:
1. Get a smithing table
2. Acquire a bronze upgrade smithing template, which can be found in chests or obtained from killing early game monsters, like zombies, skeletons, creepers, and spiders. You can duplicate it by surrounding it with copper ingots in a crafting table.
3. Craft bronze ingots from 4 copper ingots and 2 iron ingots.
4. Use the smithing table to apply the bronze upgrade.

Bronze Blocks

You can craft bronze blocks with 9 bronze ingots. From that, you can craft slabs and stairs like you would with any other material. Unlike copper, blocks of bronze do not oxidize and can be used for beacons.

Progression

This mod reworks progression to make copper a *required* tier between stone and iron. You'll need stone to mine copper and copper (or bronze) to mine iron. Bronze is an *optional* tier between copper and iron. The vanilla tool tiers have been rebalanced to use different mining speeds, attack damage, defense values, etc.

Redstone Components

Copper Wire

Copper wire is crafted with two copper ingots and one redstone dust, as shown above. This can be placed in the world and used as an alternative to redstone that isn't washed away by water, doens't need a block below it, can easily go vertically, and doesn't cause as much lag.

Rectifier

However, you'll need to use a rectifier (or logic gate) to convert redstone power to and from the kind of power used by copper wires. It can also be used in the same way as a repeater, to replenish the signal if it becomes to weak. The signal cannot go backwards.

A rectifier can be crafted with six copper ingots and one copper wire, as shown above.

The input has a dark colored square, while the output has a red square, which will be lit up when the rectifier is powered on.

Divider

If you want to turn a corner or split your wires into multiple branches, you can use a divider. However, this only takes a single input, shown with a red square, and the current will not be able to go backwards.

Logic Gates

This mod adds several logic gate blocks to the game. These can be used with both copper wires and normal redstone to simplify your contraptions and make redstone much easier! Most gates will automatically detect when an input is added and react accordingly. The following gates are added:
1. NOT gate - output is on when every input is off (can be used as a NOR gate)
2. AND gate - output is on when every input is on
3. NAND gate - output is off when every input is on (inverted AND gate)
4. XOR gate - output switches every time an input is changed
5. XNOR gate - inverted XOR gate

The OR gate was not included due to its functionality easily being replicated with a redstone wire, divider, etc. The NOR gate was removed before release due to having the same functionality as the NOT gate.

Recipes can be found in the gallery.

Compatibility

This mod has been tested and is compatible with:
- TNT's Combat
- TNT's Harder Beds
- TNT's Zombie Apocalypse
- Beddium

Adding Compatibility

If you want to add compatibility for your mod:
1. Make a folder called "tnts_useful_copper" in your mod's data folder
2. Make a folder inside of it called "tags"
3. Make a folder inside the tags folder called "blocks"
4. Add the json files you need, including the IDs of your blocks

can_provide_power.json - add anything capable of providing a redstone signal here
needs_copper_tool.json - add blocks you want to be mineable with copper, but not stone or wood
powered_by_copper_wire.json - add blocks capable of providing a redstone signal to wires
