MCEdit is an open source world editor for just about any version of Minecraft. MCEdit was first created to allow players to preserve anything built with several old versions of Minecraft and take them forward into newer versions of the game. It also aims to be forward-compatible with future (or even modified) versions of Minecraft. It has since been improved with brush tools for laying down blocks in different shapes, integration with the Minecraft Server to generate terrain using Minecraft’s own seed algorithms, support for multiplayer worlds, and editors for certain blocks including chests and mob spawners.
To get an idea of what MCEdit can do, just watch this tutorial/walkthrough by a famous mapmaker:
To download the latest MCEdit or report any problems you may have, head over to the official site. You can find downloads and other helpful links on the left sidebar, and news about the program's development will be posted regularly. If you want to share MCEdit, please only link to the official site at http://www.mcedit.net/. Don't upload MCEdit to a file sharing site or post links to the direct downloads. If you downloaded MCEdit from a site other than mcedit.net, I do not recommend using it.
MCEdit is continually under development. If you want to help, the simplest thing to do is download one of the "development" builds from the download page and play around with it. Post in this thread or on the issue tracker on GitHub if you find anything wrong. Be sure to include version (and build) numbers or your report won't be very helpful. Click on the Report an Issue link to find out what is needed for a helpful problem report.
A brief Frequently Asked Questions list is maintained on github. If your question isn't answered there, go ahead and post in this thread. If you think it should be included in the FAQ, just say so!
- Navigate the world using familiar WASD controls and mouse aiming.
- Show the locations of dropped items, game entities including monsters and villagers, hidden ores, plus blocks with TileEntities and other Minecraft internals.
- Load saved games from current Minecraft versions, plus the older Classic and Indev versions.
- Limited support for Minecraft Pocket Edition saved games
- Export blocks and game entities as a .schematic file to be imported by MCEdit or compatible programs.
- Automatically fixes wool colors when importing and exporting between Minecraft PC, Classic, and Pocket editions!
- Double-click on a chest to change its contents, or double-click on a mob spawner to choose what spawns.
- Brush tool “paints” blocks in a round, diamond, or square shape with configurable size. Different brush modes will add new blocks, replace blocks, alter the top layer of the terrain or wear it down to smooth out rough objects.
- “Paste” brush allows you to import an object with a single click.
- “Flood Fill” brush will change all blocks that form a connected mass.
- Clone tool makes a copy of blocks and entities, optionally making multiple clones in a line or scaling the copy up or down.
- Clone and Import tools can rotate an object around any axis, or flip it horizontally or vertically.
- “Filter” plugins let users add functionality to MCEdit by writing Python code.
- Move the world’s spawn point, automatically removing blocks to make sure the spawn point is acceptable to Minecraft.
- Move and rotate any player in a single- or multiplayer world.
- Expand or contract the world’s size by adding or deleting chunks. Chunks are the basis of Minecraft’s “infinite” saved game format.
- Create new worlds or add chunks to existing worlds. The Minecraft Server can be harnessed to create natural terrain that meshes with the world’s existing seed. Flatlands can also be created at any height.
- “Analyze” feature counts the block and entity types in a selected area, optionally saving them to a .csv file.
- Maintenance commands can delete all blocks, entities, or chunks in a selected region. This is useful for getting a “corrupted” world back into a playable state.
