Options

This plugin extends the BotOptions type from mineflayer. Add them to the createBot options when creating the bot. You can also change them later by changing the bot.mapDownloader properties.

Example for an option

const bot = mineflayer.createBot({
  "mapDownloader-outputDir": "some/output/dir"
})

"mapDownloader-outputDir"

Sets an output directory where maps should be saved. Maps are saved in the format map_<map id>.png where the map id has leading zeros.

"mapDownloader-saveToFile"

If maps should be saved to file. If false maps are only stored internally. Usefull if you only want to look at maps with the web viewer. Default is true

"mapDownloader-saveInternal"

If maps should be saved under maps. When downloading many maps this could prevent the process from using to much memory.

"mapDownloader-filePrefix"

Saved maps file prefix

"mapDownloader-fileSuffix"

Saved maps file suffix
