Sounds interesting, but i am not that far yet :) saved anyways, one day i`ll be on it for sure (making progress in each map i do). Right now i still have a little fight with that one. But thanks anyways

I have another problem i just found out a solution to. When i make the trigger brush eqal on both sides, so the door is inside it, the arrow that shows the connection is comming from the middle of the door, it does not work at all :) no matter which side you are on. For that i needed to use TWO trigger brushes, with different targetnames (same targetnames resultet in a permament looping trigger, which could be fine in some cases of simulating a malfunction door, but that can be done easier by script). But they have the same target. No idea thou, what will happen, once two players press USE at each side of the door. Maybe nothing, maybe only the earlier use responses, the other don`t, maybe then the sun won`t shine anymore, i really have no clue :)

Just wanted to thank again for suggestions, map works perfect. It is not done (no time now, got some exams to pass) but the doors work just perfect.

And if two players come togheter and press enter, the door moves 2 times up and then two times down again. But noone will ever notice that if it occurs from time to time :)
