This release adds copy & paste!

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:

• Changed the default color for region selection to the same as chunk selection (orange) to avoid confusion. The colors can still be changed separately in the settings.
• Copy-Paste:
  • Make a selection
  • Use Selections --> Copy chunks or press Ctrl+C (Cmd+C on Mac) to copy the selection to the clipboard.
  • Go to where you want the selection to be pasted. Copying works through instances of MCA Selector, so you can even close and reopen the program! Open a different world, stay in the same world and navigate to the desired location.
  • Use Selections --> Paste chunks or press Ctrl+V (Cmd+V on Mac) to display an overlay that shows where the chunks would be pasted.
  • Move the overlay to the desired location by pressing and holding the left mouse button.
  • Pasting can be cancelled by pressing Esc.
  • Use Selections --> Paste chunks or press Ctrl+V again to open the Import chunks dialog, prefilled with the offset values according to your choice.
  • Make your choice with the remaining options and press OK to start the import.
• Added a new option in the settings to change the color of the Pasting overlay.
• Fixed a bug where key combinations that opened a dialog would be stuck and mess with scrolling and zooming on trackpads after closing the dialog.
• Tweaked the default values for the Threadpool so MCA Selector doesn't use 100% of all available processor cores.
• A dialog with an error is now shown before the program starts when JavaFX has not been found.
• Updated the screenshots and documentation in the Readme.
• Added translation to Portuguese (Portugal) (thanks to @D3W10 for translating).

"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

If you have Java from Oracle installed on your system

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.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 on your system

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. On Windows, that java version is usually located in C:\Program Files (x86)\Minecraft\runtime\jre-x64\bin\ and once inside this folder you can simply run java.exe -jar <path-to-mcaselector-1.12.jar>. On Mac OS you should find it in ~/Library/Application\ Support/minecraft/runtime/jre-x64/jre.bundle/Contents/Home/bin/ where you can execute ./java -jar <path-to-mcaselector-1.12.jar>.

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 are using OpenJDK

If you are using a distribution of OpenJDK, you have to make sure that it comes with JavaFX, as it is needed to run the MCA Selector. Some distributions like AdoptOpenJDK (shipped with most Linux distributions) do not ship with JavaFX by default. On Debian distributions, an open version of JavaFX is contained in the openjfx package. This or some other installation of JavaFX is required to run the .jar.

If you are using Java 11 or higher

If you are using Java 11 or higher, the JavaFX modules are not included automatically. You will need to include them by specifying the module path for JavaFX. Some examples are included below, but you may need to edit paths if your system stores the JavaFX modules in a different location.

On Windows with Oracle Java 13:

"C:\Program Files\Java\jdk-13.0.1\bin\java.exe" --module-path "C:\Program Files\Java\javafx-sdk-13.0.1\lib" --add-modules ALL-MODULE-PATH -jar mcaselector-1.12.jar

On Debian with OpenJDK 11 and openjfx:

java --module-path /usr/share/openjfx/lib --add-modules ALL-MODULE-PATH -jar mcaselector-1.12.jar

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