whats ur steam what time is it where u are how long till u wake up??

create a trigger_multiple and give it a targetname e.g. "tp_first_room"
add a script_origin and give it a targetname e.g. "nacht_spawn"

add this under maps\_zombiemode::main(); in your mapname.gsc

thread rev_teleporter();

add this function at the button of the file

rev_teleporter()
{
	tp_trigger_spawn_room = getEnt ("tp_first_room","targetname");	//Define the Teleporter-Trigger
	nacht_spawn = getEnt ("nacht_spawn","targetname");				//Define the Spawnpoint
	thread teleporter_on(tp_trigger_spawn_room,nacht_spawn);		//Thread the tp function with both
}

teleporter_on(trigger,spawn)
{
	while(1)
	{
	trigger waittill( "trigger",player );
	player setOrigin( spawn.origin );
	}
}

To add a new tp to the script you only have to add the new trigger and the new script_origin into the first function like this

rev_teleporter()
{
	tp_trigger_spawn_room = getEnt ("tp_first_room","targetname");	//Define the Teleporter-Trigger
	nacht_spawn = getEnt ("nacht_spawn","targetname");				//Define the Spawnpoint
	thread teleporter_on(tp_trigger_spawn_room,nacht_spawn);	//Thread the tp function with both
 
	tp_trigger_mob = getEnt ("tp_mob","targetname");	
	first_room_spawn = getEnt ("first_room_spawn","targetname");				
	thread teleporter_on(tp_trigger_mob,first_room_spawn);
}

I think it's not too hard to understand how you add new teleporters.
If you have more questions just ask.
