Planetoids - Generates a world full of planets:
Version: v1.4.2 Release

Planetoids, by default, creates a new world (called "Planetoids", if you fail to make a settings file) that uses my custom generator class to create a world full of "planets", which are spherical objects of varying size that have a "shell" of one block type, and a "core" of another. Planetoids can also be configured to work with multi-world management plugins, serving as a chunk generator for worlds that you create.

I got the idea from the Planetoids Map Generator, but I have no affiliation with the author of that tool.


  • Configurable core and shell blocks, with percentage chance
  • Optional floor, with configurable block type and height
  • Optional single-block bedrock floor below that (to hold liquid floors)
  • Can lock it to nighttime only
  • Can disable weather, monsters, animals
  • Reads world height from Only seems to work up to 256.

Installation and Troubleshooting

A default config is created if you don't use the one from the zip, inside plugins/Planetoids. If you want to customize it before the spawn area generates (highly recommended), make sure you edit the one from the zip and put it in the right place. If you're going to use Planetoids with a multi world management plugin, I suggest you set 'autocreateworld' to FALSE, or Planetoids will make a world for itself automatically.

    @chrisvl2010: Go

    It does work in the End. I myself am trying to set it up with Multiverse to work in a normal world with night only, but I tried the End earlier and it works very well there.

    Will the generator work in the end? it seems more space-like

    I'm currently having a problem where every Planetoids world I generate is exactly the same, even after deleting the systems folder and even creating a whole new server. Some help would be greatly appreciated. :)

    It would be nicer if the spheres were a lot larger and closer together.

    This may be very complicated to code, but if the cores could be a blend of materials that could be nice.

    Specifically, I would like some planets to be similar to deep mining in vanilla minecraft, with veins of diamonds in mostly stone.

    As it is, a single diamond planet is often too much. My players will typically find a diamond planet and then get bored with the game mode. Swimming in rare resource is fun for a short while, but pursuit of more is generally the driving force in exploration for survival.

    If diamonds were simply veins in stone-core planets, that should be perfect. Ideally it would be it's own core type and can be placed with its own rarity alongside the current configuration.


    Also, and this is probably easier, having a nether generation mode would be kinda neat. Some of my players got their nether portal up and I hadn't thought about getting one created. Thought it could be possible and kinda cool.

    The plugin is partly incompatible with TreeAssist (And any simular plugin) cuz the tree/leaves one gets cut all over!!

    Popular join message plugin made by me - MOTDPlus BFAK:90704409,27665f2cff4ceda9ac46417635627463794efd6996d1f7bea0c6490737711a34

    If you could do something more like this

    I believe this plugin would be 100x more popular.

    Updated (finally) for CraftBukkit 1.4.6-R0.3. I did a general test, but as usual let me know if there are any bugs.
