Player Markers

Generate player markers with go for Mapcrafter

ExMaple

This is designed to generate player markers for a Mapcrafter map. It uses the world/playerdata/ to find the last known location of the players.

It useful in a situation where the Mapcrafter map is not on the same server as the Minecraft server or you are unable to install mods.

It uses minero-go NBT package to read and parse the player.dat. Next it will call the mojang API to retreive a username from a UUID and then it calls the Visage API to download the user skin.

After successfully retreiving all the player information it generates a js file to tell Mapcrafter to create the markers as seen here.

Use

Clone or go get the this repository.

You can modify the player-markers-tmpl.js to reflect your specific Mapcrafter setup.

Create a json config file.

Finally run playerMarkers -c=/location/of/json/config.json

NOTE: if you have other manually set markers then you will want to generate a seperate player-markers.js file which merges your existing manual markers with the player markers to create one MAPCRAFTER_MARKERS array. You will also need to modify your index.html Mapcrafter template to include this newly generated file.

Added player-markers.js under markers.js
