i want to know how I can respawn the players instead of dying when falling off the map but so that they still die if killed buy zombies?? when they respawn from falling off the map they still have all their perks guns an everything

back_to_map()
{
	fall_down_trig = getEnt ("fall_down_trig","targetname");
	fall_down_spawn = getStruct ("fall_down_spawn","targetname");
	while(1)
	{
		fall_down_trig waittill("trigger", who);
		if(IsPlayer( who ))
		{
			who DontInterpolate();
			who SetOrigin( fall_down_spawn.origin );
		}
	}
}

thread back_to_map();

So you only want to put the player back into the map after he fell down?
If so you could use this code.

back_to_map()
{
	fall_down_trig = getEnt ("fall_down_trig","targetname");
	fall_down_spawn = getStruct ("fall_down_spawn","targetname");
	while(1)
	{
		fall_down_trig waittill("trigger", who);
		if(IsPlayer( who ))
		{
			who DontInterpolate();
			who SetOrigin( fall_down_spawn.origin );
		}
	}
}

Just call this somewhere:

thread back_to_map();

In radiant you have to create a trigger multiple with the targetname "fall_down_trig" and a scriptstruct with the targetname "fall_down_spawn" where you would like to "respawn" the player.
