An open source random collection of blocks and miscellaneous cool stuff.

For stable release downloads, click here.

For snapshot versions, check the Jenkins.


What does it contain?

In (mostly) chronological order:

  • A combination ladder and trapdoor, also known as the Jaded Ladder
  • A creative-only healer block that slowly replenishes your health and food when you stand on it.
  • A guide block to assist in various constructions
  • Colorable elevator blocks to quickly travel between floors. Requires XP by default.
  • Light boxes to display your maps on the wall, ceiling or floor
  • Archery targets for a shooting range
  • Torch arrows! No longer implemented
  • Player graves, safekeeping for your last death (assuming you’re capable of regeneration)
  • Colored flags for various purposes
  • Liquid tanks-- portable, practical, and pliable any-size liquid containment
  • Hang gliders!
  • Random trophies that may or may not do odd things when right-clicked
  • Bear traps-- like venus fly traps, but snappier
  • Luggage, the traveling sentient chest
  • Sprinklers, to accelerate the growth of crops and other growables // m1.5.2, v1.0.3
  • Item cannons to shoot items around for transport
  • Vaccum hoppers-- like regular hoppers, but not limited to the top and sucks up XP. Compatible with BuildCraft!
  • Sonic goggles-- echolocation for Steves
  • Sponges for getting rid of liquids fast and effectively
  • The Redstone Configurable Pulse Lightweight Mega Touch Sensor, also known as the BIG BUTTON
  • Blocks drawn by pencils and crayons that are only seen by the imaginative eye
  • Fans-- the power of an industrial fan in the size of a desk fan
  • A wearable crane for picking up blocks and entities
  • XP Bottler-- should be self-explanatory
  • Magnet turtles-- turtles don't have CRT screens, so we should be fine
  • Village highlighter-- shows the village borders and where their golem guardians spawn
  • The Slimalizer, which detects slime chunks
  • Paths, an alternative to gravel roads // m1.6.x, v1.2.0
  • The Block Breaker and Block Placer are back! A perfect replacement for the now-dormant RedPower mod
  • XP Drain-- stand on one attached to a tank, and your XP will be drained and turned into a liquid state
  • The Auto Anvil and Auto Enchantment Table, imported fresh from OpenXP. Uses liquid XP to perform their function automatically.
  • The Sleeping Bag. Finally, a way to sleep on the go without resetting your spawn point!
  • The Rope Ladder-- a magic ladder that doesn’t need support to hold itself up and adjusts its own size to match the ground. Single use.
  • The Donation Station-- tells you which mod a block or item comes from, and lets you support the modder that created it
  • A painting/staining system for blocks, including: // m1.6.x, v.1.2.2
    • A Paint Mixer-- makes paint using dyes and milk. Millions of colors possible.
    • A paint brush to paint white canvases and other blocks.
    • Stencils that are made using the Drawing Table to paint specific areas of blocks
    • A Squeegee that liquefies paint to clean it off of blocks
  • Listen to music among other things with the radio! Killed!
  • Exciting graphics and much more to come.


We will try keep the building instructions as up-to-date as possible, but things may change without notice.


You will require msysgit or git installed with cygwin. Alternatively I would suggest installing GitHub for Windows and checking out the repo with that.

Check out the repo

Use Github for Windows or use a command prompt/powershell with git binaries in the Environment path. git clone

Change directory

cd OpenBlocks

Fetch dependencies (OpenModsLib etc.)

git submodule init
git submodule update

Run gradle build

OpenBlocks uses Forge Gradle build system, as almost any other mod this days. There are few good tutorials, so we will include just basic command for building:

gradle.bat build

The resulting files should be in the build/lib folder. File ending with -deobf is unobfuscated version for development use.

Linux or OSX

Much the same as Windows, open a terminal window where you wish to checkout the repo and type

git clone
cd OpenBlocks
git submodule init
git submodule update

In OSX, git is typically supplied. Otherwise it can be installed through the apps thingy that OSX has (Obviously I know very little about OSX but you want the dev tools stuff).

(To install git and other command line tools on OS X, tun xcode-select --install in the terminal (/Applications/Utilities/

The linux git can be fetched from any package manager. If you're on a Debian based machine (This includes Ubuntu) you likely have aptitude, so the command would be sudo apt-get install git.

If you're running a RedHat based system, such as CentOS or Fedora (or some other Distro I've never heard of), then you might have the yum package manager sudo yum install git-core. In the case that this does not work through yum, you might not have the packages added to yum to be able to find git. I wont go in to these here, but if you have issues feel free to contact NeverCast in #OpenMods on

Then run gradle

OpenBlocks uses Forge Gradle build system, as almost any other mod this days. There are few good tutorials, so we will include just basic command for building:

./gradle build

The resulting files should be in the build/lib folder. File ending with -deobf is unobfuscated version for development use.
