Copper was a cool addition to Minecraft. It's a common metal that you can find large amounts of. However, now that the copper golem is not selected, it's pretty much a useless item.

To fix this issue, I changed some of the recipes that previously required iron to use copper instead. This makes copper more relevant. Moreover, these changes make previously over-expensive items like hoppers and rails more accessible to a casual survival playthrough.

This datapack not only changes the recipes, but also includes a resourcepack to make the items look the part. Don't forget to grab that as well.

The copper armor set replaces the chainmail armor set from vanilla. Its stats are therefore the same: Between gold and iron.

The copper sword replaces the stone sword from vanilla.

The sticky piston retexture is compatible with vanilla tweaks' sticky piston sides option.

Make sure your language is set to US English, or the renamed items won't display correct names.

UPDATES:

1.1: Remade hopper's texture.
