A minecraft mapping experiment written in compose multiplatform. It reads minecraft player-created maps and joins them together into a mosaic which is viewable in a browser. A Nether subway route overlay can be shown as well, if route and stop data has been configured.

Prebuild development snapshots of the backend tool and web client are available. There is also a desktop client and an android client.

Run ./gradlew shadowJar and copy mcmapper-backend.jar and your backend JSON configs to your minecraft server. Look in the example-backend-config/ directory for an example config.

Run ./gradlew jsBrowserWebpack then copy the contents of the js/ directory to your web root.

To use the webapp you will need to periodically run the backend tool on the minecraft server. It will read your minecraft maps and write the resulting JSON and PNG data into the web root. If your web root is, for example, /var/www/html/ then you might want to copy the webapp into /var/www/html/mc/ and the map data into /var/www/html/mc/data/

java -jar mcmapper-backend.jar convert-map /path/to/my/worlds.json /var/www/html/mc/data/

Copy client/webpack.config.d/proxy.js.example to client/webpack.config.d/proxy.js and edit the proxy url to point to the data directory on the webserver where mcmapper-backend.jar runs. Run ./gradlew jsBrowserDevelopmentRun to build.
