Population Density


Automatically places new players where they can find wood, animals, ore, and space to build. Also priority-based login queue, reserved slots for admins, idle boot ONLY when nearly full, entity thinning for lag reduction, and optional limited teleportation. Never again will your players experience a marathon run, spawn room full of portals, or maze of abandoned builds. This is a zero maintenance solution for administrators, and players don't need to learn any commands!

This video explains the region post system to new players.
See below for information on administrative features.

Feature Summary

  • Assigns starting points for new players so that they can ALWAYS find space to build and beginner resources nearby. Players may be spawned directly there, or you can tell them about a slash command which will take them there.
  • Respawns animals, regrows grass, and replants trees in the new player area to guarantee important new player resources.
  • Removes idle players ONLY when the server is nearly full.
  • Login queue to ensure fairness when your server is full, can prioritize some players over others if you like.
  • Reserved slots for administrators.
  • Optional teleportation posts which help players socialize and trade, but aren't abuse-able to escape combat or save a lost or hungry player.
  • "Thins" extremely-dense crowds of monsters and animals, preventing ridiculous levels of farming or monster grinding from lagging your server.


Server owners often underestimate the badness in starting a player in a crowded area. Sure seeing builds makes your server look legitimate, but having to explore a long time just to find space to build and beginner resources is a major turn off for players who want to start playing right away. Even when players do find a place to start playing, they're often alone because other new players wandered into different areas.

PopulationDensity is the low-maintenance, easy-for-players answer to all these problems.

It works by automatically locating a region with lots of wood and ore, and then dropping new players in that region until they collect most of the easily accessible ore, cut down most of the trees, or crowd it with builds. Then PopulationDensity finds a new resource-wealthy region for future newbies and starts dropping new players there. If you have a great spawn area built up, you can instead spawn players there, and later tell them to use /HomeRegion when they're ready to start adventuring (or another command you define in commands.yml).

Additionally, optional teleportation commands help players move around quickly to admire builds and socialize while not compromising the game's integrity - players can only teleport from automatically-placed teleportation posts, so teleportation can't be used as an "easy-out" for players who mine or adventure themselves into trouble. That way, players keep the challenge of single player without the "players are too far apart" multiplayer issue.

Finally, if you have a "my server is always full" problem, then congratulations on your successful server! :) With PopulationDensity, you may optionally boot players who are idling so more players can log in and have fun, increasing your feel-good factor (or fattening your wallet, for some). when the server IS full, a login queue guarantees fairness, and administrative slots are set aside to guarantee administrators can always get in.

You can also assign players a queue priority to help them get on the server faster during peak times, to reward them for contributing to the server monetarily or through your community.

More Great Plugins!

My plugins solve Vanilla problems in ways which minimize impact on servers, administrators, and players, so everybody can enjoy Minecraft without having to learn to play the game in a new way or spend more time administrating than playing. My goals are effectiveness, simplicity, and efficiency. If you like this plugin, check out more of my work:

  • Grief Prevention
    • Prevents ALL types of grief, cheaply.
    • Easy for players and admins, mostly automatic.
    • Players claim land to prevent theft and house wrecking.
    • Automatically warn, mute, and kick or ban spammers.
    • Blocks dumping lava and setting fire on another player in non-PvP servers.
    • Disable fire damage, spread, or both.
    • Wipe away ugly builds with a right-click - no database required!
    • Automatically prevents spawn camping in PvP servers.
    • Prevent damage to the surface by limiting lava and water placement, and TnT damage.

    • Includes a creative mode for creative worlds.
    • Optional siege mode for build-based PvP.
  • Anti-XRay
    • Limits how quickly players can mine valuables, based on their play time / values mined ratio.
    • Keeps your valuables in the ground, so non-cheating players can find them (unlike ore loggers).
    • Practically free to run, unlike the tremendously expensive Orebfuscator.
    • Most legit players won't notice, but xrayers will ragequit and move on.

    I think populationdensity count ice block as player created block. That will make some wilderness region will be skipped.

    @JonyPooh: Go

    No, I asked if you ran out of space at some other point in time. Anyways...

    This seems to indicate that either a) part of your world is corrupt, and thus hanging when PopulationDensity goes and loads up chunks to scan, b) your hard drive is on its last legs, causing I/O problems as chunks are loaded when it scans chunks, or (unlikely) c) your CPU is too slow, since it's likely the watchdog killing your server.

    I'm venturing to guess it's one of the two above. I'd run the world via a region fixer such as this one: https://github.com/Fenixin/Minecraft-Region-Fixer as well as running hard disk utilities such as whatever Linux' chkdsk equivalent and SMART test utilities.

    @The_PC_Tech_Guy: Go

    I just double checked. Not close to running out of space;

    Also, I tried resetting the population density data and now the server becomes unresponsive after is see this... [18:20:12 INFO]: PopDensity: Examining available resources in region "0 0"... And then the server restarts. Population Density isn't working at all.

    Did you run out of hard drive space at one point?

    @drdoct: Go

    Use commands.yml to map /spawn to essentials:spawn. http://wiki.bukkit.org/Commands.yml

    @Orniej: Go

    @dahbawz: Go

    How close are the horses to you? This was implemented to allow players to teleport horses and other pets with them. There might be a config option for this, if I recall correctly...

    Same thing happening here, When players do /randomregion, all there horses teleport with them. Plugins are essentials en population density.

    No error's in logs nor console.
