Visualize your WorldEdit selection with particles!

About This Plugin

Broad overview

  • This plugin visualizes your current WorldEdit selection with some fancy particles!
  • You can customize the shown particle effect, their amount and enable an advanced grid (useful for bigger selections). To take a look at other options, look at the configuration section below! Covered are cuboid, spherical, ellipsoid, cylinder and 2D polygonal selections (see below for examples).
  • One of the other features is the display of your copied selection (of //copy), which can be toggled with the WESUI command. You can also show a specific WorldGuard region by using the /wesui showregion command

If you want to run this plugin on a 1.8.x server, you have to download a legacy version from the GitHub Releases page!


... This plugin mimics the functionality of the popular WorldEditCUI client mod, but running as a serverside plugin, so that you/your users do not need to install any mods. The main difference I wanted to achieve compared to similar plugins is on simplicity, performance and memory impact by choosing a rather simplistic and direct approach to calculating vectors, but you can check these for yourself.


This plugin works with the following versions and forks of WorldEdit:


Available commands and their permissions are: \

  • /wesui - wesui.command
  • /wesui reload - wesui.command.reload
  • /wesui toggle - wesui.command.toggle
  • /wesui toggleclipboard - wesui.command.toggleclipboard
  • /wesui showregion <region> - wesui.command.showregion

wesui.maxselectionsize.bypass - bypass the selection size limit set in the config

# If enabled, the positions for particles will only be calculated once per selection and then cached.
# This essentially entirely removes the higher CPU usage of the calculations, but results in some caching if many/big selections are being made.
# Disable this if you run into concurreny errors.

Setting Particles With Data

... If you want to use particles that require extra data (REDSTONE, FALLING_DUST, BLOCK_DUST, BLOCK_CRACK, ITEM_CRACK) or want to set speed, part-particle view-distance, or offsets, you also need to put that extra data in the config (note that the REDSTONE particle is only changeable for 1.13+ servers).

All of the below are examples - the important bits are what follows the X-particle-data key!

Let's say you want to set the normal selection particle to REDSTONE and change radius and offset; Then your config should look similar to this:

particle: REDSTONE
  # RGB color data - numbers from 0 to 255
  r: 0 # red
  g: 0 # green
  b: 0 # blue
  # Relative particle size
  size: 0.9
  # Generic settings
  radius: 50
  offX: 0.2
  offY: 0.1
  offZ: 1

You can also add the speed parameter to the -data section, being a decimal number from 0 to 1. [/SIZE]Note that some particles do not support setting their speed.

Now you want to set the clipboard particle to FALLING_DUST (works the same for BLOCK_DUST and BLOCK_CRACK):

clipboard-particle: FALLING_DUST
  # Block material
  material: DIAMOND_BLOCK

Finally, you want to set the others-particle field in send-particles-to-all to ITEM_CRACK:

  others-particle: ITEM_CRACK
    material: STICK

IMPORTANT: If you are running a server on 1.12 or lower, you need to note the following when using either BLOCK_CRACK, BLOCK_DUST, or FALLING_DUST:

  • after the material, you might also need the extra data/durability. E.g. brown wool is just YELLOW_WOOL in 1.13+, but in 1.12- it is WOOL with data 4, so you would write it as in the following example:

particle: FALLING_DUST
  material: WOOL
  data: 4

You can obviously put any of the particles in any of the fields; I just used different ones to illustrate its structure.
