Old VeinMiner

Chain-mine entire ore veins with a single block break.
A VeinMiner mod for Minecraft 1.4.7 + Forge.

---

How It Works

Hold the activation key (` by default) and break a block. All connected blocks of the same type are chain-mined in a single operation. Drops go straight to your inventory.

• 26-directional flood fill with distance-priority (closest blocks first)
• Works with ores, leaves (shears), and any connected blocks
• Redstone ore variants (lit/unlit) treated as the same vein
• Tool durability consumed per block, mining stops if tool breaks
• Hunger cost proportional to blocks mined

Install

1. Install Minecraft Forge 1.4.7
2. Download ovm-*.jar from Releases
3. Drop it into your mods/ folder
4. Launch the game

Configuration

Edit config/ovm.cfg after first launch:

Option	Default	Description
maxBlocks	64	Maximum blocks mined per vein operation
hungerPerBlocks	32	Blocks mined per 1 hunger point (0 = free)
dropsToInventory	true	Deliver drops to inventory (overflow at feet)
activationKey	41	LWJGL keycode (41 = grave/backtick `)

Building from Source

Requires Docker (amd64 emulation on Apple Silicon).

# Build the Docker image (first time only, ~15 min)
docker build -t veinminer-dev .

# Compile and package
bash scripts/build.sh

Output: ovm-<version>.jar in the repo root, auto-deployed to 1.4.7/minecraft/mods/ if present.

Architecture

src/com/ovm/
  OvmMod.java          # Forge mod entry point, tick handler
  OvmClientHandler.java # Client: key polling, break detection, packet sending
  OvmPacketHandler.java # Server: packet reception, dynamic proxy
  VeinMiner.java        # Server: flood fill, block breaking, drop collection
  McAccessor.java       # Cached reflection accessors for Minecraft objects
  Reflect.java          # Reflection utilities for obfuscated member access
  OvmConfig.java        # Forge configuration

All Minecraft members accessed via dual-name reflection (MCP + obfuscated), since FML's RelaunchClassLoader does not remap mod code at runtime.
