Minecraft – WorldEdit – replace block if condition is true

minecraft-java-editionminecraft-worldedit

I have a significant amount of chunks of farmland on some hills that I want to plant crops on all at once. I'm considering using WorldEdit to do this but I don't want to just select the whole general area of the farmland and replace all air with seeds (this actually works, from prior experience on a more powerful server) because it'll probably crash my server.

Is there a way to use conditional statements to the effect of "if air block is directly above farmland replace with seeds" to plant these seeds?

The best and easiest way to do this is just to do //overlay seeds.

This places seeds above all of the blocks exposed to the sky in the selection.

You can do this using block probability patterns.

Most places you'd normally enter a single block type in WorldEdit, you can instead enter one of these which will give you a random distribution of blocks instead of just one kind. You can specify which blocks and how often they should show up.

As an example, if you were to select a zone and enter the following command you'd end up with something like the following screenshot:

//replace grass,dirt 50%cloth:red,50%cloth:white

Pattern distribution example

Note that you cannot specify a probability pattern for the blocks you are going to replace - only for what you will replace them with.

Assuming you already have the stone brick walls laid out, you just want a brush that replaces some of the stone bricks with mossy or cracked stone bricks. The below commands will give you a brush with a radius of 5 that exclusively targets stone brick (all kinds, including mossy and cracked) and replaces it with 70% regular stone brick (stonebrick:0), 10% mossy stone brick (stonebrick:1) and 20% cracked stone brick (stonebrick:2).

/brush sphere 70%stonebrick:0,10%stonebrick:1,20%stonebrick:2 5

/mask stonebrick

Just tweak the probabilities until you get an effect you like. You might want to make certain areas more mossy, or certain areas less mossy and more cracked, so play with it a bit.

Minecraft – Why don’t I have permission to use WorldEdit

Due to the nature of worldedit, worldedit requires you to specify permissions, either the build in, or by using a permissions plugin

Worldedit uses the WEPIF (WorldEdit Permissions Interoperability Framework) to handle permissions.

If you're not using a permissions plugin, the easiest way is using Flat file permissions which allows you to simply give yourself all permissions by editing two files in the root of your server (same location as bukkit itself):

perms_groups.txt

admins:*

perms_users.txt

sk89q:admins:*

(replace sk89q with your username)

There's a list of permissions, on the Worldedit Wiki which can help you if you want to further specify permissions
