WorldEdit v1.0 for MineTest 0.4
===============================
In-game world editing for [MineTest](http://minetest.net/)! Tons of chat commands to help with building, fixing, and more.

For more information, see the [forum topic](http://minetest.net/forum/viewtopic.php?id=572) at the MineTest forums.

Usage
-----
WorldEdit works primarily through chat commands. Depending on your key bindings, you can invoke chat entry with the "t" key, and open the chat console with the "F10" key.

WorldEdit has a huge potential for abuse by untrusted players. Therefore, users will not be able to use WorldEdit unless they have the "worldedit" privelege. This is available by default in single player, but in multiplayer the permission must be explicitly given by someone with the right credentials, using the follwoing chat command: `/grant <player name> worldedit`. This privelege can later be removed using the following chat command: `/revoke <player name> worldedit`.

For in-game information about these commands, type `/help <command name>` in the chat. For example, to learn more about the `//copy` command, simply type `/help /copy` to display information relevant to copying a region.

WorldEdit API
-------------
WorldEdit exposes all significant functionality in a simple interface. Adding WorldEdit to the file "depends.txt" in your mod gives you access to all of the `worldedit` functions. These are useful if you're looking for high-performance node manipulation without all the hassle of writing tons of code.

### worldedit.volume(pos1, pos2)

Determines the volume of the region defined by positions `pos1` and `pos2`.

Returns the volume.

### worldedit.set(pos1, pos2, nodename)

Sets a region defined by positions `pos1` and `pos2` to `nodename`. To clear to region, use "air" as the value of `nodename`.

Returns the number of nodes set.

### worldedit.replace(pos1, pos2, searchnode, replacenode)

Replaces all instances of `searchnode` with `replacenode` in a region defined by positions `pos1` and `pos2`.

Returns the number of nodes replaced.

### worldedit.copy(pos1, pos2, axis, amount)

Copies the region defined by positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z") by `amount` nodes.

Returns the number of nodes copied.

### worldedit.move(pos1, pos2, axis, amount)

Moves the region defined by positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z") by `amount` nodes.

Returns the number of nodes moved.

### worldedit.stack(pos1, pos2, axis, count)

duplicates the region defined by positions `pos1` and `pos2` along the `axis` axis ("x" or "y" or "z") `count` times.

Returns the number of nodes stacked.

### worldedit.dig(pos1, pos2)

Digs a region defined by positions `pos1` and `pos2`.

Returns the number of nodes dug.

### worldedit.serialize(pos1, pos2)

Converts the region defined by positions `pos1` and `pos2` into a single string.

Returns the serialized data and the number of nodes serialized.

### worldedit.deserialize(originpos, value)

Loads the nodes represented by string `value` at position `originpos`.

Returns the number of nodes deserialized.
