Minetest-WorldEditAdditions

Extra tools and commands to extend WorldEdit for Minetest

If you can dream of it, it probably belongs here!

Current commands:

Quick Reference:

//floodfill [<replace_node> [<radius>]]

Floods all connected nodes of the same type starting at pos1 with <replace_node> (which defaults to water_source), in a sphere with a radius of (which defaults to 50).

//floodfill
//floodfill water_source 50
//floodfill glass 25

//overlay <node_name>

Places <replace_node> in the last contiguous air space encountered above the first non-air node. In other words, overlays all top-most nodes in the specified area with <replace_node>.

Will also work in caves, as it scans columns of nodes from top to bottom, skipping every non-air node until it finds one - and only then will it start searching for a node to place the target node on top of.

Note that all-air columns are skipped - so if you experience issues with it not overlaying correctly, try //expand down 1 to add an extra node's space to your defined region.

//overlay grass
//overlay glass
//overlay grass_with_dirt

//ellipsoid <rx> <ry> <rz> <node_name>

Creates a solid ellipsoid at position 1 with the radius (rx, ry, rz).

//ellipsoid 10 5 15 ice
//ellipsoid 3 5 10 dirt
//ellipsoid 20 10 40 air

//hollowellipsoid <rx> <ry> <rz> <node_name>

Creates a hollow ellipsoid at position 1 with the radius (rx, ry, rz). Works the same way as //ellipsoid does.

//hollowellipsoid 10 5 15 glass
//hollowellipsoid 21 11 41 stone

//torus <major_radius> <minor_radius> <node_name>

Creates a solid torus at position 1 with the specified major and minor radii. The major radius is the distance from the centre of the torus to the centre of the circle bit, and the minor radius is the radius of the circle bit.

//torus 15 5 stone
//torus 5 3 meselamp

//hollowtorus <major_radius> <minor_radius> <node_name>

Creates a hollow torus at position 1 with the radius major and minor radii. Works the same way as //torus does.

//hollowtorus 10 5 glass
//hollowtorus 21 11 stone

//maze <replace_node> [<path_length> [<path_width> [<seed>]]]

Generates a maze using replace_node as the walls and air as the paths. Uses an algorithm of my own devising. It is guaranteed that you can get from every point to every other point in generated mazes, and there are no loops.

Requires the currently selected area to be at least 3x3x3.

The optional path_length and path_width arguments require additional explanation. When generating a maze, a multi-headed random walk is performed. When the generator decides to move forwards from a point, it does so path_length nodes at a time. path_length defaults to 2.

path_width is easier to explain. It defaults to 1, and is basically the number of nodes wide the path generated is.

Note that path_width must always be at least 1 less than the path_length in order to operate normally.

The last example below shows how to set the path length and width:

//maze ice
//maze stone 2 1 1234
//maze dirt 4 2 56789

//maze3d <replace_node> [<path_length> [<path_width> [<path_depth> [<seed>]]]]

Same as //maze, but adapted for 3d - has all the same properties. Note that currently there's no way to adjust the height of the passageways generated (you'll need to scale the generated maze afterwards).

Requires the currently selected area to be at least 3x3 on the x and z axes.

The optional path_depth parameter defaults to 1 and allows customisation of the height of the paths generated.

//maze3d glass
//maze3d bush_leaves 2 1 1 12345
//maze3d dirt 4 2 2
//maze3d stone 6 3 3 54321

//bonemeal [<strength> [<chance>]]

Requires the bonemeal (repo) mod (otherwise WorldEditAdditions will not register this command and outut a message to the server log).

Bonemeals all eligible nodes in the current region. An eligible node is one that has an air node directly above it - note that just because a node is eligible doesn't mean to say that something will actually happen when the bonemeal mod bonemeals it.

Optionally takes a strength value (that's passed to bonemeal:on_use(), the method in the bonemeal mod that is called to actually do the bonemealing). The strength value is a positive integer from 1 to 4 (i.e. 1, 2, 3, or 4) - the default is 1 (the lowest strength).

I observe that a higher strength value gives a higher chance that something will actually grow. In the case of soil or sand nodes, I observe that it increases the area of effect of a single bonemeal action (thus at higher strengths generally you'll probably want a higher chance number - see below). See the bonemeal mod README for more information.

Also optionally takes a chance number. This is the chance that an eligible node will actually get bonemealed, and is a positive integer that defaults to 1. The chance number represents a 1-in-{number} chance to bonemeal any given eligible node, where {number} is the chance number. In other words, the higher the chance number the lower the chance that a node will be bonemealed.

For example, a chance number of 2 would mean a 50% chance that any given eligible node will get bonemealed. A chance number of 16 would be a 6.25% chance, and a chance number of 25 would be 2%.

//bonemeal
//bonemeal 3 25
//bonemeal 4
//bonemeal 1 10
//bonemeal 2 15

//walls <replace_node>

Creates vertical walls of <replace_node> around the inside edges of the defined region.

//walls dirt
//walls stone
//walls goldblock

//multi <command_a> <command_b> <command_c> .....

Executes multi chat commands in sequence. Intended for WorldEdit commands, but does work with others too. Don't forget a space between commands!

//multi //1 //2 //shift z -10 //sphere 5 sand //shift z 20 //ellipsoid 5 3 5 ice
//multi //1 //hollowtorus 30 5 stone //hollowtorus 20 3 dirt //torus 10 2 dirt_with_grass
//multi /time 7:00 //1 //outset h 20 //outset v 5 //overlay dirt_with_grass //1 //2 //sphere 8 air //shift down 1 //floodfill //reset

//y

Confirms the execution of a command if it could potentially affect a large number of nodes and take a while. This is a regular WorldEdit command.

//y

//n

Prevents the execution of a command if it could potentially affect a large number of nodes and take a while. This is a regular WorldEdit command.

Troubleshooting

If you're experiencing issues with this mod, try checking this FAQ before opening an issue.

I get an error saying that worldedit isn't installed

WorldEditAdditions requires that the worldedit mod is installed as a dependency. Install it and then try launching Minetest (or the minetest-server) again.

I get an error saying that worldedit.register_command() is not a function

This is probably because your version of worldedit is too old. Try updating it. Specifically the worldedit.register_command() function was only added to worldedit in December 2019.
