Well I gess I wont change the grating, I will keep it solid and not from many parts.
I got another question. This map is going to be abit like crossfire, in each of those rooms(like the one you see in the screeni) there is a button, when all the buttons are pressed they will activate a multisource that will cause acid to flood all the rooms but those 6 reletivly small rooms(2 are bigger and two of their parts are connected by long staircases). How can I make the buttons only reset a few minutes after the flooding is over?
Also I have another problem. Where should I place the spawning points. It can't be in the rooms.(If people will die when they try to reach the rooms to escape the acid they will spawn in the rooms and they will be saved) The main room is really dangerous, but I'm still not sure if I should or should not. The only place that is perfect to place them is in the sewer tunnel that surrounds the whole chamber, but the only exit from it is from the lower two rooms. That meens that after killing a few players that are left in the main chamber, you wont have to fight any more...
BTW: The question about the buttons is more important for,maybe, I can place a ladder/elevator somewhere... :
Edit:
Thanks you convinced me it will be better as func_walls.
