The theory

How did we manage to render a map on top of the screen?

Don't skip this!

The Plugin

The plugin simply uses the built-in map features of Minecraft and accordingly draw colored pixels on the map to make it live!

Wether your map has rotation active, there's mob nearby or you are tracking a specific waypoint the map will take care of all of this and display its things accordingly, and this is server side.

The Shader

The shader doesn't care of all these info, she just want to see the actual map on the screen, after she sees it, it performs some checks on the actual map, looking for certain pre-determined colored pixels at certain pre-determined positions and makes his magic, and this is client side.

This is how we manage to create a bridge of interaction between the client and the server, so it's no dark magic stuff, well, kind of..
