mcaselector-1.13

This release adds new features for selections and filters. And a lot of bug fixes.

ATTENTION: This release contains internal changes to how chunk deletion, export and import works. Make backups before doing anything you might regret in the future! If you encounter a bug, please create a bug report HERE.

Details:

• Selections can now be inverted:
  • Press Ctrl+U (Cmd+U on Mac) to invert a selection. This should work with all existing features involving selections, like deleting, exporting and changing chunks but also copying and importing chunks.
• Group filters can now be negated using a ! before a group. E.g. !(xPos < -10 OR xPos > 10) will select a vertical strip in the middle of the world.
• Added a Dutch translation (thanks to @Clijmart for translating)
• Added an Italian translation (thanks to @valeilsimpaticone for translating)
• Added a Polish translation (thanks for @Marcinolak for translating)
• Updated the gradle wrapper to 6.6.1 and fixed all related deprecation errors.
• Added instructions to create a .bat or .sh file to run MCA Selector.
• Added unit tests for rendering the map, importing chunks and some small tests for filters.
• Fixed instructions about how to execute MCA Selector using PowerShell
• Fixed a bug where switching a filter condition for another would forget the comparator and operator. When switching "compatible" conditions (e.g. xPos to zPos), they will retain their operator, comparator and value.
• Fixed a bug where the Status filter would not work.
• Fixed a bug where the file dialog would throw an exception and not open if the current world directory was deleted while MCA Selector was running.
• Failing to log something should not interfere with the main program anymore.
• Fixed a bug where logging an exception could throw an uncaught NPE
• Fixed a bug where the css was not minified correctly in the final jar.
• Fixed a bug where de-fragmenting an mca-file would throw an exception if the last chunk was not padded.
• Fixed a bug where biome indexes were calculated incorrectly for Minecraft 1.15+.
• Fixed a rare bug where any text in MCA Selector would be rendered incorrectly ("garbled text") by bundling a custom font with the final jar.
• Fixed a bug where MCA Selector would attempt to create images if no world was loaded.
• Reworked version specific implementations for rendering, filtering and changing NBT data for easier support of future versions without breaking old versions.

MCA Selector modifies and deletes chunks in your Minecraft world. Please make backups of your world before using.

"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-1.13.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-1.13.jar into the console and press Enter. In the Command window (Windows 8 and earlier), the command starts with "C:\Program Files (x86)\Minecraft\runtime\jre-x64\bin\java" -jar instead and the path to mcaselector-1.13.jar must be typed or copied and pasted into the console manually.

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-1.13.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-1.13.jar, an error dialog appears that looks like this:"

Open the console or terminal on your OS.

For Windows:

• Hold Shift and Right-click on an empty space on your desktop and select Open PowerShell here (Open Command window here on Windows 8 and earlier).

For MacOS:

• Press Cmd+Space, type Terminal and press Enter.

Type the command java -version and press Enter. If the output shows that your java command is linked to java version "1.8.0", you can simply run MCA Selector through the console.

For Windows and MacOS:

• Type java -jar (with a space at the end) and drag and drop the mcaselector-1.13.jar into the console and hit Enter.

For Linux:

• Run java -jar <path to mcaselector-1.13.jar where you replace everything in <>.

If the output shows a Java version higher than Java 8, 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-1.13.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-1.13.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 run java --module-path <path to unzipped folder>/lib --add-modules ALL-MODULE-PATH -jar <path to mcaselector-1.13.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-1.13.jar.

To avoid having to go through this process every time to start MCA Selector, the resulting command can be copied into a .bat-file on Windows or .sh-file on MacOS and Linux and can then be executed by double-clicking the .bat-file on Windows or running sh <file>.sh in the terminal / console on MacOS or Linux where <file> must be replaced by the name of the .sh-file.

mcaselector-1.12.3

This release fixes some bugs.

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 filtering for chunks containing air wouldn't work correctly
• Fixed a bug where LOCALAPPDATA on Windows was divided into two paths because it was using the same code used for Linux that divided environment variables containing multiple paths into their individual pieces.
• Updated entity mappings to include new entities added in recent snapshots
• Updated installation instructions to include a Java version check in the console.

mcaselector-1.12.1

This release fixes some bugs and changes default directories.

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 with an offset would not correctly relocate TileEntities.
• Copying Entities now generates new UUIDs so Minecraft doesn't delete Entities with duplicate UUIDs.
• Changed default directories to make use of OS directories for cache, log files and settings:
  • Windows:
    • Cache directory: %LOCALAPPDATA%\mcaselector\cache if %LOCALAPPDATA% is set, otherwise <parent directory of mcaselector.jar>\mcaselector\cache
    • Log file: %LOCALAPPDATA%\mcaselector\debug.log if %LOCALAPPDATA% is set, otherwise <parent directory of mcaselector.jar>\mcaselector\debug.log
    • Config file: %LOCALAPPDATA%\mcaselector\settings.ini if %LOCALAPPDATA% is set, otherwise <parent directory of mcaselector.jar>\mcaselector\settings.ini
  • MacOS:
    • Cache directory: ~/Library/Caches/mcaselector
    • Log file: ~/.log/mcaselector/debug.log
    • Settings file: ~/Library/Application Support/mcaselector/settings.ini
  • Linux:
    • Cache directory: $XDG_CACHE_DIR/mcaselector if $XDG_CACHE_DIR is set, otherwise ~/.cache/mcaselector
    • Log file: ~/.log/mcaselector/debug.log
    • Config file: ~/.mcaselector
• The cache directory and log file can be configured by adding the options BaseCacheDir and LogFile to the config file. In headless mode when generating cache files, the output directory must still be provided with the --output parameter.
• The log file directory can now be opened by clicking a link in the settings.
• Updated the Readme accordingly.

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- .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-1.12.1.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-1.12.1.jar

On Debian with OpenJDK 11 and openjfx:

java --module-path /usr/share/openjfx/lib --add-modules ALL-MODULE-PATH -jar mcaselector-1.12.1.jar

mcaselector-1.12

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).

Details:

• Fixed a bug where the map view mixed up cache files when opening a world while the previous world was still generating images.
• Fixed a bug where Sections without a Palette were spamming exceptions.
• Fixed a bug where the Nether would not render as the Nether if the chunks were from Minecraft 1.13.
• Improved rendering of the Nether by skipping more block types.
• When rendering a chunk fails, it is now visible in the map view.
• The current version number is now visible in the window title.
• Cleaned up the code.

"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-1.11.1.jar

On Debian with OpenJDK 11 and openjfx:

java --module-path /usr/share/openjfx/lib --add-modules ALL-MODULE-PATH -jar mcaselector-1.11.1.jar

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

mcaselector-1.11

This release adds support for deleting and importing specific vertical sections of chunks.

This update adds new features that can be useful when migrating a world to 1.16. Here is a document with some tips and tricks regarding 1.16.

Details:

• Fixed spanish translation (thanks to @NathanielFreeman.
• Fixed some information regarding compatibility in the Readme. MCA Files were first introduced in 1.2.1, not Beta 1.3.
• Removed unused icon for a "default NBT tag" from resources.
• Improved rendering for underwater features, now showing hints of the color of the blocks and better showing the depth of the water. This can still be disabled in the settings.
• Added support for comma separated ranges when deleting chunks. The field DeleteSections now accepts ranges in the format <from>:<to>. E.g: 3:7 means "all sections from 3 to 7, inclusive". From and to can be omitted to define no upper and/or lower bounds, e.g. :7 means "all seaction up to 7, inclusive".
• Added support for custom entities with custom namespaces in the chunk filter. Defining an entity without a namespace automatically assumes the namespace minecraft:. Use single quotes to define custom entities. When using single quotes, a namespace must be defined.
• Added support to import specific sections when importing chunks:
  • The field uses the same range syntax as the DeleteSections field in the NBT Changer.
  • Merges Biomes, Entities, TileTicks, TileEntities, LiquidTicks, Lights, LightsToBeTicked, ToBeTicked and PostProcessing fields.
  • When merging into an empty or non-existing chunk, its Status is set to full.
  • Entity UUIDs are randomized to avoid duplicates.
  • Minecraft does weird things with biomes, so they might not show up correctly in game.
• Updated dependencies to use NBT 5.5.
• Updated documentation, discord badge and screenshots in the Readme.
• Fixed a crash when processing indexed but nonexistent chunks in region files.
• Fixed a memory overflow error when logging too many exceptions.
• Fixed an error that occurred when drawing chunks of an "optimized" world.

"Requirements":

• Either:
  • JRE 8+, you can get it from HERE
  • A Minecraft Java Edition installation
• A computer
• 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-1.11.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-1.11.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-1.11.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 Debian with OpenJDK 11 and openjfx:

java --module-path /usr/share/openjfx/lib --add-modules ALL-MODULE-PATH -jar mcaselector-1.11.jar

mcaselector-1.10

This release makes everything more pretty!

Details:

• Added shading to show different height levels. Shading can be disabled in the settings to return to the old render style. Shading for water can be turned of separately, as it might be slower than shading for land.
• Made rendering slightly faster by writing directly to an int array instead of the PixelWriter for every pixel.
• Added DeleteSections feature to the NBT Changer. It works similar to DeleteEntities; setting it to 1 or true it will delete all sections of the chunks. This only works for already generated chunks, so in order to make e.g. a Skyblock world, you would need to let Minecraft generate the world first before deleting the sections. Biomes, Entities and the bounding boxes of structures will persist of not otherwise specified in the NBT Changer.
• Biome in the NBT Changer can now be set to -1 to force Minecraft to regenerate all biomes.
• Filter conditions can now be moved using drag-and-drop.
• Added a text field below the filter editor that shows the current filter as a query that can be used in headless mode. Pasting a query into this text field and pressing Enter will also parse the text and display it in the filter editor above.
• Fixed a bug where checking if a filter applies to a region file before opening the file would not work correctly.
• Status in the Chunk Filter and the NBT Changer should validate correctly now using the most recent allowed values.
• Minimized the distributed jar file to exclude unused classes from dependencies.
• Updated Readme with more detailed information on how the filter logic works, see #107.
• Fixed some CSS in group filters. Nested group filters are more visible now and more consistent with the overall look of the other filters.
• Larger-than-or-equal and does-not-contain sign now use the correct unicode character.
