Mini-Map Viewer

I was wondering quite along time, so i decided to post this...

Is there any possibility to create something that could clear out the mini-map? Let's say that u enter a dungeon, u can only see what u discovered in the map, right? So lets imagine that we couild create something that could clear it, very usefull when trying to find treasure rooms and etc.

Or is that type of content server sided?



Note: I dont have any knowledge on any type of programming!


Thanks in advance, and please dont write hate messages!

map is fully server sided. also this was asked like a dozen times before.
