I have no idea what this is, but it sounds cool.
Is it those Hologram Emitter Things?
Nein
I was on a server about half years before. When I spawned I saw a brick with a print over it.
I thought I got a center print, but when I looked away, it wasn't there. I checked the events, and I did find out, that its name is setbricktext. It is similar to the holografic emmiters and crap, but its like the
client>>centerprint as an emmiter.
I'd want it really much!
