Rock Hardness & Tool Mechanics

One of the core mechanics of PFAA is the implementation of rock hardness. Unlike vanilla Minecraft where all stone is uniform, PFAA rocks are categorized into four hardness levels. This affects which tools can harvest them and the durability of tools crafted from them.

Hardness Levels and Tool Interaction

Hardness Level Value Harvest Tool Required Drop Type Stone Tool Durability
Weak 1.0 Wooden Pickaxe Rubble 25% of Vanilla
Medium 2.0 Stone Pickaxe Cobblestone 50% of Vanilla
Strong 3.0 Stone Pickaxe Cobblestone 100% of Vanilla
Very Strong 4.0 Iron Pickaxe Intact Stone 100% of Vanilla

Harvesting Mechanics

  • Rubble: Harvesting Weak stone (typically sedimentary) yields Rubble. Rubble behaves similarly to gravel but does not drop flint. It can be used to craft low-durability stone tools.
  • Cobblestone: Medium and Strong rocks yield their respective cobblestone variants. These can be smelted back into solid stone in a furnace.
  • Intact Stone: Very Strong rocks are harvested as solid blocks. To obtain the cobblestone variant for crafting or building, players must use extra processing methods such as a Rock Crusher.

Mineral Ores & Distribution

PFAA introduces a wide variety of realistic ores. These ores do not spawn randomly but are tied to specific host rocks and strata.

Major Ore Types

  • Iron Ores: Hematite (found in sedimentary/metamorphic), Magnetite (igneous), Limonite, and Siderite.
  • Copper Ores: Native Copper, Tetrahedrite, Malachite, and Azurite.
  • Tin Ores: Cassiterite (primarily found in Granite and Pegmatite).
  • Lead & Zinc: Galena (lead/silver) and Sphalerite (zinc).
  • Precious Metals: Native Gold and Native Silver.
  • Industrial Minerals: Chromite, Cinnabar (mercury), Molybdenite, and Wolframite (tungsten).

Ore Generation Patterns

  1. Primary Stratum: The main layer of the crust in a specific area.
  2. Localized Stratum: A horizontal deposit of limited size within a primary layer.
  3. Intrusion: Vertical or diagonal veins of igneous rock that often carry rare minerals.

Crafting & Smelting

PFAA modifies existing recipes to ensure compatibility with its new rock types through the Ore Dictionary.

Key Recipes

  • Stone Tools: Crafted using Rubble (Weak) or Cobblestone (Medium/Strong). The durability is automatically adjusted based on the material used.
  • Stone Bricks: Crafted from 4 blocks of the same rock type (Stone or Cobblestone).
  • Slabs & Walls: All PFAA rock types support the standard vanilla-style recipes for slabs, walls, and stairs.
  • Smelting: Cobblestone of any type can be smelted in a furnace to return to its smooth Stone form.

Ore Processing

When integrated with other mods, PFAA ores can be processed through multiple stages: 1. Crushing: Breaking the ore block into Crushed Ore. 2. Grinding: Reducing crushed ore into Dust. 3. Purification: Using chemical baths or centrifuges to separate trace metals (e.g., Silver from Galena).
