Getting started


  • RopeMC
  • Minecraft 1.8.8
  • Java Runtime Enviroment 8
  • JavaFX
    • This depends on your operating system. On GNU/Linux, it is called most likely "openjfx" or "java-openjfx" (i.e. Debian/Ubuntu/Mint or Arch), but this depends on your distribution. Otherwise it should be included in every JDK.


Download the latest version of RopeMC from the releases tab.


Open your .minecraft folder, which is located in Roaming. You can access it through these two methods:

Windows → Run → Prompt %appdata% → Enter → .minecraft
Windows + R → Prompt %appdata% → Enter → .minecraft

Place your downloaded .jar file into the .minecraft-directory and rename it to RopeMC.jar.


Your minecraft folder is located under

*Volume*/Users/*User*/Library/Application Support/minecraft

which is invisible at default. How to access it is explained here!


Open your .minecraft folder, which is located in $HOME/.minecraft. Access it through the terminal or a File Manager (e.g. Nemo). Your .minecraft-folder may be hidden because it is a dotfile-directory. You can toggle the visibility either through

View → Show hidden Files

or just use Ctrl+H as a shortcut. These methods should work in almost every file manager on GNU/Linux.

Continue the installation

Open your Minecraft Launcher and create a new profile. You need to use Minecraft 1.8.8, right now it is the only supported version for RopeMC.
Enable your Advanced Java Settings, enable JVM-Arguments and add the following to the end of the line:


Your profile should look something like this:

alt text

An example could be:

-Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -javaagent:RopeMC.jar

Save your changes. You should be ready to go! 👍

After launching RopeMC, the programm should created a folder named RopeMC in your Minecraft-directory. Please place your mod in
