https://github.com/querz/mcaselectorA specialized utility for Minecraft Java Edition players and server administrators to manage world saves. MCA Selector allows users to select, export, import, or delete specific chunks and regions. It features a graphical user interface and a command-line interface (CLI) with modes for NBT value changes, cache image generation, and filter-based queries.
MCA Selector is available for multiple platforms. Always download directly from the official GitHub repository to ensure safety.
⚠️ Warning: MCA Selector modifies and deletes chunks in your Minecraft world. Please make backups of your world before using it.
Available distributions for version 2.8:
.exe).dmg) and x64 (.dmg).deb (arm64/x64) and .rpm (arm64/x64).jar (requires Java runtime)ParamExecutor, or if the execution completes, the application attempts to launch the graphical user interface using Window.launch. Note that a functional JavaFX installation is required for the GUI to run. If JavaFX is missing, an error dialog will be shown and the application will exit.Before using MCA Selector, ensure your Minecraft world version is supported. The tool maps Minecraft versions to specific DataVersion ranges. Note that there is no guarantee for worlds generated in Snapshot versions, and old Snapshots are not officially supported.

You must specify a mode using the --mode (or -m) flag.
Available modes:
select: Create a selection from a filter query and save it as a CSV file.export: Export chunks based on a filter query and/or a selection.import: Import chunks with an optional offset.delete: Delete chunks based on a filter query and/or a selection.change: Change NBT values in an entire world or only in chunks based on a selection.cache: Generate the cache images for an entire world.image: Generate a single image based on a selection.ParamExecutor to process arguments. If the provided arguments result in a successful execution of a command (returning true from the execution future), the application will exit with code 0. If arguments are provided that do not trigger a command-line specific task, the application proceeds to launch the graphical user interface (GUI).
