Terraformer

A Terraformer is a command block device used exclusively by operators and helpers to modify and sculpt the land features in Escharon. They usually hang in the sky overhead between 90 and 130 blocks and resemble large floating slabs. As such, they are only accessible to players with the ability to fly.

Terraformers are used in-game, unlike MCEdit, and essentially change the user into a square brush (typically 2x2), modifying the ground beneath the player to whatever the terraformer is configured to. This has the advantage of quickly changing large swaths of land in a short amount of time, and is particularly useful in filling in large bodies of water, or removing landmasses entirely by simply "erasing them" from existence.

Terraformers are often configured for single player use, meaning they will only respond to a specific player's motions or commands. This prevents them from being used by visitors to grief the servers. They are typically destroyed after use to prevent abuse or misuse.

Design
The typical Terraformer design is a simple 3 x 5 x 2 stone block structure with 6 command blocks embedded within it, in various configurations. The most common configuration has "fill layer" switches which control what type of block will be filled at which height range. However more advanced Terraformer designs have been created for various in-game purposes, including tunnelers, coast creators, and mountain builders.

For instance, one command block may fill everything beneath the player's position from z=5 to z=62 (sea level), with stone block. When this command block is switched on, then everything beneath the player's position where ever he or she moves, will be filled with this block type. Typically multiple command blocks are activated at once to "raze" an area.

Terraformer command blocks are used for one player only; and are hard coded to a specific player's gamertag. As such, they cannot be used by other players. This is done to prevent griefing or misuse by new players.
