Minecraft is a commercial game very popular with geeks. It's a game about blocks. You can build a computer out of the game thanks to logical switches. There is a parallel world. Zombies, pigs, spiders, sheeps, wolves that you can tame, etc... This wiki page is here to help you install the game :)
You can install minecraft by using the available package in AUR. This package provides the official launcher and a convenient script for launching minecraft. Upon running minecraft it will procced to download the lastest version and install it in Template:Filename
Setting Up Java
Minecraft should work out-of-the-box with a couple of the various Java JREs.
Minecraft should just work with openjdk6 in community.
# pacman -S openjdk6
If on openJDK7 minecraft gets stuck in the pause menu, you may be able to get it to work following these instructions:
Manually forcing minecraft to use LWJGL 2.8.1 seems to solve the pause screen problem (and, as a bonus, fixes the sticky keys issue). Credit goes to MrIso on reddit. LWJGL 2.8.1 can be downloaded here:
Replace the following files in .minecraft/bin/ with the corresponding versions in lwjgl-2.8.1/jar
jinput.jar lwjgl.jar lwjgl_util.jar
And from .minecraft/bin/natives/ with lwjgl-2.8.1/natives/linux
libjinput-linux.so libjinput-linux64.so liblwjgl.so liblwjgl64.so libopenal.so libopenal64.so
Play the game
Run minecraft with :
$ java -jar $HOME/.minecraft/minecraft.jar
If you want to allocate it more ram, do like this :
$ java -jar -Xms1024M -Xmx2048M $HOME/.minecraft/minecraft.jar
There are several programs and editors which can make your Minecraft experience a little easier to navigate. The most common of these programs are map generators. Using one of these programs will allow you to load up a Minecraft world file and render it as a 2D image, providing you with a top-down map of the world.
Minutor is described as a minimalistic map generator for Minecraft. Don't let this mislead you, it generates maps of existing worlds, not the other way around. You are provided with a simple GTK based interface for viewing your world. Several rendering modes are available, as well as custom coloring modes and the ability to slice through z-levels. Minutor is available in the AUR.
Minecraft is also available as a server, which will allow you to share a world with other players over the Internet. Here's what you'll need to do:
- Follow the steps above to install Java (or OpenJDK)
- Download the multiplayer beta server jar from the Minecraft site
- Just run the jarfile:
(You can sub the -Xmx and -Xms values for the amount of memory you want your server to use. A good rule of thumb is one GB per ten users.)
$ java -jar -Xmx2048M -Xms2048M -jar minecraft_server.jar nogui
- To configure the server, take a look at this wiki page.
- You may wish to create a specific folder for the server (/srv/minecraft, for example)
- Establishing a Minecraft-specific user is recommended for security. The reason for this is that Minecraft, being beta software, may still contain security holes. By setting it to a specific, unprivileged user account, anyone who successfully exploits your Minecraft server will have only gotten access to your unprivileged user. (Meaning, do not ever run the server as root!) Here's how:
- Use 'adduser' to add the user
- Disable that user's individual login by removing the password (you can still 'sudo su - mineserver' to open a shell as the user)
- Set the new user as owner of all the server files (generated on the first run) by running 'chown -R mineserver:nobody /path/to/server'
- To leave the server running unattended, take a look into tmux, nohup or screen
- Taking this a step further, you may even decide to create an init script for it, such as this one.
- (Please note that the script at that link doesn't quite work with Arch entirely. I haven't had the opportunity to troubleshoot it fully yet, but anyone with time and expertise to do so is encouraged to post one on my talk page and I'll find a proper place for it.)
- Finally, you may wish to modify your server, to provide additional features:
- You might even set up a cron job with a mapper to generate periodic maps of your world
- ...or you could use rsync to perform routine backups (though this is one function of the init script above)
