Doom3world

I have a question i would like to ask about making maps; You know in Doom 3 RoE one level while you were on a tram it stops, you see a hellknight teleport in on something, pick up a dead body and throw it at you lol, then teleport away, here are my two questions, one, how do you make him throw that guy, must i write a script? and two; how do i make him teleport out, like i know how to make him teleport in just set teleport value 1 to the monster and he teleports in when triggered but i really have no clue how to teleport out please help.
thx

The best thing to do when learning is to open up the maps that come with the game and study the script and the map file. It's more or less what I did when Doom 3 was released.
