Bukkit

With this plugin installed, rename a diamond pick (with an anvil) to the name of "branchminer" and then start mining stone, gravel, dirt, cobblestone, and grass. Any diamond pick named "branchminer" will instantly break the next 25 blocks in front of you once the first block is broken.

The plugin will skip any block that is not stone, gravel, dirt, cobblestone, or grass, so if there's any ores in the tunnel being mined, you can break it with a silk touch or fortune pick.

The pick is configurable. You have the ability to add other blocks you want that the branchminer pick can mine, or remove some if you feel that the pick mines too much. Additionally, you can set a minimum Y limit and a maximum Y limit, so the pick will only mine in the range provided.

Tip: You can also add a number at the end of the name of the pick to adjust the number of blocks in front of you it breaks, like this: "branchminer 30". This will mine thirty blocks in front of whoever used the pick.

The default configuration file (plugins/ExtremeBranchMiner3000/config.yml) should look like this:

branchminable_blocks: stone,dirt,gravel,cobblestone,grass
maximumYHeight: '250'
minimumYHeight: '0'
lengthLimit: '500'

To configure what blocks the branchminer mines, simply add or remove the names of the blocks after branchminable_blocks. Remember to put a comma after each one except the last, and do not have any spaces in this. Use underscores if the desired material is two words or more. The maximumYHeight and the minimumYHeight are integers and you can set them to whatever you want. The branchminer pick will not break any block under the minimumYHeight or above the maximumYHeight.
