About this project
What does No Copper add?
No Copper
A standalone Minecraft Fabric mod managed by the PCKR Engine that eliminates copper generation, converts existing copper items into iron counterparts, and offers custom Copper Golem building rules.
Features
- Worldgen Replacement: Intercepts chunk decoration to replace all copper ore and deepslate copper ore features with configured alternatives (Iron, Stone, or Dirt).
- Crafting Conversions: Adds recipes (5:1 ratio) to convert copper resources to iron counterparts, so you can enjoy decorations without the mining junk of copper:
- 5 Copper Ingots → 1 Iron Ingot
- 5 Raw Copper → 1 Raw Iron
- Custom Copper Golem Construction: Spawns a vanilla Copper Golem using 1 Iron Block + 1 Carved Pumpkin (requires no horizontally adjacent iron blocks to prevent conflict with Iron Golem construction).
- On-Demand Retroactive Replacement: Sweeps all loaded server chunks upon running the
/pckr reloadcommand, replacing all residual copper ores with the configured block type.

How to Build Copper Golems
Place 1 Iron Block, then place 1 Carved Pumpkin on top of it. Ensure there are no other iron blocks directly next to the base iron block to prevent triggering an Iron Golem spawn.
