Hi, since im new to mapping and there are currently no tutorials on how to add zones in bo3. I tried to follow the tutorials on zoning in cod5 but things seem to have changed. Anyway when i try to add "add_adjacent_zone("spawn", "spawnnorth", "enter_spawn" );" to my map.gsc file all it does is crash my game. Any help is appreciated.

function usermap_test_zone_init()
{
	//level flag::init( "always_on" );
	//level flag::set( "always_on" );

	zm_zonemgr::add_adjacent_zone("start_zone", "zone1", "enter_zone1" );

}

It's almost exactly the same process except for the scripting part. Set up your zones how you want them in Radiant like you would WaW. But when adding adjacent zones do this:
Go to "root/usermaps/MAPNAME/scripts/zm/MAPNAME.gsc" and comment out the first two lines, and then add the "zm_zonemgr" line for every zone you wish to add.

function usermap_test_zone_init()
{
	//level flag::init( "always_on" );
	//level flag::set( "always_on" );

	zm_zonemgr::add_adjacent_zone("start_zone", "zone1", "enter_zone1" );

}

It works, but im not sure what adjacent zones i should link. This is my current layout: http://prnt.sc/col43g and i cant get zombies only to spawn in opened zones, they just keep spawning in unopened zones as well. Do you know how to fix this?
