This release fixes a bug and changes default directories again.

Update 1.11 added new features that can be useful when migrating a world to Minecraft 1.16. Here is a document with some tips and tricks regarding 1.16.

Details:

  • Fixed a bug where importing chunks without using Copy-Paste would throw an NPE.
  • Fixed the default directories for cache, logs and settings to comply with XDG and changed the Log file directory for MacOS (see Readme).
  • It doesn't make sense to store the path of the config file inside the config file...

"Requirements":

  • Either:
    • 64bit JRE 8+, you can get it from HERE
    • A Minecraft Java Edition installation
  • A computer
    • At least 6 GB of RAM. If lower, more RAM has to manually be assigned to the JVM using the -Xmx argument. Assigning 4 GB is recommended.
  • A brain

What works on most systems

Most likely, .jar files are associated with java on your computer, it should therefore launch by simply double clicking the file (or however your OS is configured to open files using your mouse or keyboard). If not, you can try java -jar mcaselector-1.12.2.jar from your console. If this doesn't work, you might want to look into how to modify the PATH variable on your system to tell your system that java is an executable program.

If you have Minecraft Java Edition installed

Minecraft Java Edition comes with a JRE that you can use to start the MCA Selector, so there is no need to install another version of Java on your system.

For Windows:

  • Hold Shift and Right-click on an empty space and select Open PowerShell window here (Open Command window here on Windows 8 and earlier).
  • Type C:\Program Files (x86)\Minecraft\runtime\jre-x64\bin\java -jar , then drag and drop the mcaselector-1.12.2.jar into the console and press Enter.

For MacOS:

  • Press Cmd+Space, type Terminal and press Enter.
  • Type ~/Library/Application\ Support/minecraft/runtime/jre-x64/jre.bundle/Contents/Home/bin/java -jar (with a space at the end), then drag and drop the mcaselector-1.12.2.jar into the console and press Enter.

WARNING: For MacOS 10.14+ (Mojave) It is NOT recommended to use the JRE provided by Minecraft (1.8.0_74), because it contains a severe bug that causes JavaFX applications to crash when they lose focus while a dialog window (such as the save-file-dialog) is open (see the bug report here). This bug has been fixed in Java 1.8.0_201 and above.

If you receive a JavaFX error

"When I run mcaselector-1.12.2.jar, an error dialog appears that looks like this:"

Popup dialog stating a missing JavaFX installation

Please find and download the appropriate JavaFX version from Here. If you know what to do, do it. If you don't, follow these steps:

For Windows:

  • Download "JavaFX Windows SDK" for your Java version from here.
  • Unzip the .zip-file with your program of choice, then navigate into the unzipped folder.
  • Hold Shift and Right-click on an empty space in that folder and select Open PowerShell window here (Open Command window here on Windows 8 and earlier). Type java --module-path (with a space at the end), then drag and drop the lib-folder into the console. Continue to type --add-modules ALL-MODULE-PATH -jar (with a space at the beginning and the end), then drag and drop the mcaselector-1.12.2.jar into the console and hit Enter`.

For MacOS:

  • Download "JavaFX Mac OS X SDK" for your Java version from here.
  • Double-click the .zip-file to unpack, then navigate into the unzipped folder.
  • Press Cmd+Space, type Terminal and press Enter. Type java --module-path (with a space at the end), then drag and drop the lib-folder into the console. Continue to type --add-modules ALL-MODULE-PATH -jar (with a space at the end), then drag and drop the mcaselector-1.12.2.jar into the console and hit Enter.

For Linux:

  • Download "JavaFX Linux SDK" for your Java version from here.
  • Unzip the .zip-file with your program of choice.
  • Open the command prompt and type java --module-path <path to unzipped folder>/lib --add-modules ALL-MODULE-PATH -jar <path to mcaselector-1.12.2.jar> where you replace everything in <> with the appropriate paths.
  • Some distributions like AdoptOpenJDK (shipped with most Linux distributions) do not ship with JavaFX by default. On Debian, an open version of JavaFX is contained in the openjfx package. This or some other installation of JavaFX is required to run the mcaselector-1.12.2.jar.

If none of these instructions work, apply "A brain" that you providently held ready after having read the "Requirements" section carefully. Or ask your question on Discord.
