//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_a> [<chance[<snowballs|...> [<key_1> [<vaue_1>]] [<key_2> [<value_2>]] ...]_a>] <node_name_b> [<chance_b>] [<node_name_N> [<chance_N>]] ...
Places <node_name_a> 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 <node_name_a>. Optionally supports a mix of node names and chances, as //mix (WorldEdit) and //replacemix (WorldEditAdditions) does.
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.
Note also that columns without any air nodes in them at all are also skipped, so try //expand y 1 to add an extra layer to your defined region.
//overlay grass
//overlay glass
//overlay grass_with_dirt
//overlay grass_with_dirt 10 dirt
//overlay grass_with_dirt 10 dirt 2 sand 1
//overlay sandstone dirt 2 sand 5
//layers [<node_name_1> [<layer_count_1>]] [<node_name_2> [<layer_count_2>]] ...
Finds the first non-air node in each column and works downwards, replacing non-air nodes with a defined list of nodes in sequence. Like WorldEdit for Minecraft's //naturalize command, and also similar to we_env's //populate. Speaking of, this command has //naturalise and //naturalize as aliases. Defaults to 1 layer of grass followed by 3 layers of dirt.
The list of nodes has a form similar to that of a chance list you might find in //replacemix, //overlay, or //mix - see the examples below. If the numberr of layers isn't specified, 1 is assumed (i.e. a single layer).
//layers dirt_with_grass dirt 3
//layers sand 5 sandstone 4 desert_stone 2
//layers brick stone 3
//layers cobble 2 dirt
//forest [<density>] <sapling_a> [<chance_a>] <sapling_b> [<chance_b>] [<sapling_N> [<chance_N>]] ...
Plants and grows saplings to generate a forest. A density value is optionally taken, which controls the overall density of the forest that is generated. The bonemeal mod is required - just like for the //bonemeal command.
The density defaults to 1, acts like a multiplier, and is not affected by the chances of all saplings listed (e.g. you can have a sapling with a chance of 1-in-50, and the overall density of the forest will be unaffected). For example, 2 results in a forest twice as dense as the default, and 0.5 a forest half as dense as the default density.
The tree types are provided as a list of names and 1-in-N chances, just like //overlay, //mix, //layers, etc. Unlike the aforementioned commands however, //forest has an additional layer of alias resolution to ease the process of determining what the name of the sapling is you want to use to generate forests with. See //saplingaliases for more details.
Saplings are placed with //overlay and grown using the same method that's used by the //bonemeal command. Up to 100 attempts are made to grow placed saplings. If all of those attempts fail (success is determined by whether the sapling is still present or not), the sapling is removed and the failure counter is incremented.
Currently, the following mods are known to have aliases registered:
defaultmoretrees(warning: these saplings don't appear to work very well this command - assistance in debugging this would be very helpful)cool_trees
If you like, you can also reference the full name of a sapling node instead. The only requirements for saplings to be supported by this mod are:
- It can be bonemealed
- It has the
saplinggroup
For example, the first 2 examples below are functionally equivalent.
//forest aspen
//forest default:aspen_sapling
//forest 2 oak 3 aspen pine
//forest 0.5 acacia
//saplingaliases [aliases|all_saplings]
Lists all the currently registered sapling aliases in alphabetical order. These aliases can be used in the
Optionally takes a single parameter, which is the operating mode. Current implemented operating modes:
| Mode | Description |
|---|---|
aliases |
The default. Lists all the currently registered sapling aliases in alphabetical order. |
all_saplings |
Spins through all the nodes currently registered in Minetest, and lists all the nodes that have the sapling group. |
//saplingaliases
//saplingaliases all_saplings
//saplingaliases aliases
//fillcaves [<node_name>]
Fills in all airlike nodes beneath non airlike nodes, which gives the effect of filling in caves. Defaults to filling in with stone, but this can be customised.
//fillcaves
//fillcaves dirt
//fillcaves brick
//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). Alias: //flora.
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
//replacemix <target_node> [<chance>] <replace_node_a> [<chance_a>] [<replace_node_b> [<chance_b>]] [<replace_node_N> [<chance_N>]] ...
Replaces a given node with a random mix of other nodes. Functions like //mix.
This command is best explained with examples:
//replacemix dirt stone
The above functions just like //replace - nothing special going on here. It replaces all dirt nodes with stone.
Let's make it more interesting:
//replacemix dirt 5 stone
The above replaces 1 in every 5 dirt nodes with stone. Let's get even fancier:
//replacemix stone stone_with_diamond stone_with_gold
The above replaces stone nodes with a random mix of stone_with_diamond and stone_with_gold nodes. But wait - there's more!
//replacemix stone stone_with_diamond stone_with_gold 4
The above replaces stone nodes with a random mix of stone_with_diamond and stone_with_gold nodes as before, but this time in the ratio 1:4 (i.e. for every stone_with_diamond node there will be 4 stone_with_gold nodes). Note that the 1 for stone_with_diamond is implicit there.
If we wanted to put all of the above features together into a single command, then we might do this:
//replacemix dirt 3 sandstone 10 dry_dirt cobble 2
The above replaces 1 in 3 dirt nodes with a mix of sandstone, dry_dirt, and cobble nodes in the ratio 10:1:2. Awesome!
Here are all the above examples together:
//replacemix dirt stone
//replacemix dirt 5 stone
//replacemix stone stone_with_diamond stone_with_gold
//replacemix stone stone_with_diamond stone_with_gold 4
//replacemix dirt 3 sandstone 10 dry_dirt cobble 2
//convolve <kernel> [<width>[,<height>]] [<sigma>]
Advanced version of //smooth from we_env, and one of the few WorldEditAdditions commands to have any aliases (//smoothadv and //conv).
Extracts a heightmap from the defined region and then proceeds to convolve over it with the specified kernel. The kernel can be thought of as the filter that will be applied to the heightmap. Once done, the newly convolved heightmap is applied to the terrain.
Possible kernels:
| Kernel | Description |
|---|---|
box |
A simple uniform box blur. |
pascal |
A kernel derived from the odd layers of Pascal's Triangle. Slightly less smooth than a Gaussian blur. |
gaussian |
The default. A Gaussian blur - should give the smoothest result, and also the most customisable - see below. |
If you can think of any other convolutional filters that would be useful, please open an issue. The code backing this command is very powerful and flexible, so adding additional convolutional filters should be pretty trivial.
The width and height (if specified) refer to the dimensions of the kernel and must be odd integers and are separated by a single comma (and no space). If the height is not specified, it defaults to the width. If using the gaussian kernel, the width and height must be identical. Larger kernels are slower, but produce a more smoothed effect and take more nearby nodes into account for every column. Defaults to a 5x5 kernel.
The sigma value is only applicable to the gaussian kernel, and can be thought of as the 'smoothness' to apply. Greater values result in more smoothing. Default: 2. See the Gaussian blur page on Wikipedia for some pictures showing the effect of the sigma value.
//convolve
//convolve box 7

//convolve gaussian 9 10
//convolve gaussian 5 0.2
//erode [<snowballs|...> [<key_1> [<value_1>]] [<key_2> [<value_2>]] ...]
Runs an erosion algorithm over the defined region, optionally passing a number of key - value pairs representing parameters that are passed to the chosen algorithm. This command is experimental, as the author is currently on-the-fence about the effects it produces.
Currently implemented algorithms:
| Algorithm | Mode | Description |
|---|---|---|
snowballs |
2D | The default - based on this blog post. Simulates snowballs rolling across the terrain, eroding & depositing material. Then runs a 3x3 gaussian kernel over the result (i.e. like the //conv / //smoothadv command). |
Usage examples:
//erode
//erode snowballs
//erode snowballs count 25000
Each of the algorithms above have 1 or more parameters that they support. These are detailed below.
Algorithm: snowballs
Based on the algorithm detailed in this blog post (direct link to the source code), devised by Job Talle.
| Parameter | Type | Default Value | Description |
|---|---|---|---|
| rate_deposit | float |
0.03 | The rate at which snowballs will deposit material |
| rate_erosion | float |
0.04 | The rate at which snowballs will erode material |
| friction | float |
0.07 | More friction slows snowballs down more. |
| speed | float |
1 | Speed multiplier to apply to snowballs at each step. |
| max_steps | float |
80 | The maximum number of steps to simulate each snowball for. |

| maxdiff | float |
0.4 | The maximum difference in height (between 0 and 1) that is acceptable as a percentage of the defined region's height. |
| count | float |

If you find any good combinations of these parameters, please open an issue (or a PR!) and let me know! I'll include good combinations here.
//count
Counts all the nodes in the defined region and returns the result along with calculated percentages (note that if the chat window used a monospace font, the returned result would be a perfect table. If someone has a hack solution to make the columns line up neatly, please open an issue :D)
//count
//subdivide <size_x> <size_y> <size_z> <cmd_name> <args>
Splits the current WorldEdit region into (<size_x>, <size_y>, <size_z>) sized chunks, and run //<cmd_name> <args> over each chunk.
Sometimes, we want to run a single command on a truly vast area. Usually, this results in running out of memory. If this was you, then this command is just what you need! It should be able to handle any sized region - the only limit is your patience for command to complete.....
Note that this command only works with WorldEdit commands, and only those which require 2 points (e.g. //torus only requires a single point, so it wouldn't work very well - but //set or //clearcut would).
Note also that <cmd_name> should not be prefixed with any forward slashes - see the examples below.
Warning: Once started, this command cannot be stopped without restarting your server! This is the case with all WorldEdit commands, but it's worth a special mention here.
//subdivide 10 10 10 set dirt
//subdivice 25 25 25 fixlight
//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
//many <times> <command>
Executes a single chat command many times in a row. Uses minetest.after() to yield to the main server thread to allow other things to happen at the same time, so technically you could have multiple //many calls going at once (but multithreading support is out of reach, so only a single one will be executing at the same time).
Note that this isn't necessarily limited to executing WorldEdit / WorldEditAdditions commands. Combine with //multi (see above) execute multiple commands at once for even more power and flexibility!
//many 10 //bonemeal 3 100
//many 100 //multi //1 //2 //outset 20 //set dirt
//ellipsoidapply <command_name> <args>
Executes the given command, and then clips the result to the largest ellipsoid that will fit inside the defined region. The specified command must obviously take 2 positions - so for example //set, //replacemix, and //maze3d will work, but //sphere, //torus, and //floodfill won't.
//ellipsoidapply set dirt
//ellipsoidapply maze3d dirt 4 2 2
//ellipsoidapply erode
//ellipsoidapply replacemix sand bakedclay:red bakedclay:orange
//ellipsoidapply layers desert_sand sand 2 desert_sandstone 4 sandstone 10
//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.
//n
Far Wand
The far wand (worldeditadditions:farwand) is a variant on the traditional WorldEdit wand (worldedit:wand). It looks like this: 
It functions very similarly to the regular WorldEdit wand, except that it has a much longer range - which can be very useful for working on large-scale terrain for example. It also comes with an associated command to control it.
//farwand skip_liquid (true|false) | maxdist <number>
This command helps control the behaviour of the WorldEditAdditions far wand. Calling it without any arguments shows the current status:
//farwand
You can decide whether you can select liquids or not like so:
//farwand skip_liquid true
//farwand skip_liquid false
You can change the maximum range with the maxdist subcommand:
//farwand maxdist 1000
//farwand maxdist 200
//farwand maxdist 9999
Note that the number there isn't in blocks (because hard maths). It is however proportional to the distance the wand will raycast looks for nodes, so a higher value will result in it raycasting further.
