they are possible, and from what i hear from others who've tried making them, they're easy too. "someone" is hiding something regarding the reason sauer has no MP triggers yet >_>

ive tried it on a random server in sauer (but still an open server, no auth) and it didnt worked when i tried insta with it. of course the echos do work, but thats all, no teleport or door that worked...

Nothing really hidden about it, just nobody has any interest in overhauling the entire system in Sauer (and possibly breaking legacy support to do so). I had to rewrite the whole system to pull it off myself (and move a lot from engine code to game code).

and i really like you did that :) (respect for such thing)!
even tough i like it more when its added on such game like sauerbraten, that hasnt got a speficic theme (futuristic and unreal, but still maps wich could be today or even in the past, like urban_c or c_egypt. this is probabaly just because it looks like the roots has been build with the idea not to take a complete different theme as cube 1).
im not sure of course if red eclipse is like that, but as far as i noticed from blood frontier, its more futuristic based then sauerbraten.

Those are in Red Eclipse already =3
