The only VeinMiner for Minecraft 1.4.7

Old VeinMiner brings chain-mining to Minecraft 1.4.7 — a version no other VeinMiner mod supports.

Hold the activation key (` by default) and break a block. The entire connected vein is mined instantly, with drops delivered straight to your inventory.

Features

26-directional flood fill — mines diagonally connected blocks, closest first
All mineable blocks — ores, leaves (with shears), and any connected block type
Smart drops — compacted into stacks, delivered to inventory (overflow drops at feet)
Tool durability — consumed per block, stops if your tool breaks
Hunger cost — proportional to blocks mined (configurable, or disable it)
Redstone-aware — lit and unlit redstone ore treated as the same vein
Fully configurable — max blocks, hunger cost, activation key, drop behavior

Configuration

Edit config/ovm.cfg after first launch:

Option	Default	Description
`maxBlocks`	64	Max blocks mined per operation
`hungerPerBlocks`	32	Blocks per hunger point (0 = free)
`dropsToInventory`	true	Drops go to inventory vs. drop in world
`activationKey`	41	LWJGL keycode (41 = `)

Install

Install Minecraft Forge for 1.4.7
Drop ovm-*.jar into your mods/ folder
