FOSS gamedev and creative worlds

or maybe magick beacons in our setting.

First variant: These are blocks or signs or something like this, which you can place, and write the word over it. And this word should be visible at any point of the world, just like usernames do now. They should be user-specific, so you don't flood screen of other users.

Second variant, more technical: you can do this without any blocks at all. You need only to store the coordinates and text and without rendering anything, just calculate the right position according to coordinates and draw the word there. This can be done at the client side without any interaction with the server.

Something like
/# mark -90,0,-356 "Izengard Tower"

Server-side marks can be introduced also, if server admin want to show some specific places to all users.

cool and you maybe could use that to make /#teleport Izengard Tower so you can teleport by word im no genius so i have no idea as to how this could be done

Not sure if this is what you want but there is a fork that appears to have teleport blocks:
