lol Sorry if I haven't responded to any messages anywhere. Lately I've been away from all online communications except Steam and Xfire.
As for what you saw on School of War, I made that... it's basically a hack of JA+. I learned a long time ago (many years) that slider left some beta testing commands inside JA+, and me and BobaFett (well, he did most of the work at that time) once did the same thing for JA+ 2.3 beta 1 on linux only... then a couple years ago, I decided to go back and check the newer versions on windows, and lo and behold, things were still in there.
In simple terms, JA+ has some "locked" admin commands that slider made for beta testing (he told me this himself once) that he didn't remove from the game, but simply made them impossible to use... unless you use a little reverse engineering. It's actually not too difficult and would probably make for a nice tutorial on codecaving, BUT the noclip feature was not a part of this and took more work on my part to accomplish (and my method is not that elegant or versatile, but it served my purposes). For that I basically just figured out where in the assembly code the game would check for admin permissions on any command and had the noclip code jump to that spot instead of going to the code that checks for cheat protection (or maybe I rewrote the admin check ASM... I don't remember :/). At any rate, what you saw on my server was most likely a combination of noclip, invisibility, and efx-playing commands used simultaneously, to give the appearance of a teleport, rather than an actual "new" teleport command (although I like how it turned out because it gives you full control of where you want to "reappear").
In any case, you can't do it without some kind of coding, either adding to an existing mod or hacking something already there. IIRC, you can almost do it in JA++ now, but I don't remember if there was an actual playefx type of feature being added, or if it was only entspawn.
