i'm making a moon style intro where you start out in one zone stay there until you get overwhelmed and then run to the teleporter and the game actually begins. i got the spawning to work but my problem is with riser zombies they just spawn at the spawner instead of rising from the ground. i know the risers are working properly because when i started working on this i just set the intro_zone to be the starting zone and the risers worked correctly

spawn_zombies()
{
	introSpawners = getEntArray("intro_spawner","targetname");
	level thread award_grenades_for_survivors();
        while(level.teleport_count < level.players_playing)
	{
		spawn_point = introSpawners[RandomInt( introSpawners.size )]; 
		spawn_zombie(spawn_point);
	}
}

this is the script i'm using to spawn the zombies in the intro zone.
if anyone can tell me why the risers arent spawning correctly it would be greatly appreciated! thanks for any help in advance

So the start_zone here:

	// Initial Zone(s) -- Zone(s) You Want Activated At Map Start
	zones = [];
	zones[ zones.size ] = "start_zone";
	level.DLC3.initialZones = zones;

in your mapname.gsc is not 'intro_zone' but the zone you teleport to, and you use this script to spawn zombie's before the players reach the start_zone?
Then it's maybe because your intro_zone is not activated, so the riser-structs arent active.

is there a way to switch which zone is active and which one isnt active? ive tried setting the intro_zones's isActive variable to false and then calling enable_zone from the zone_manager to enable the new zone but it did nothing but diable the intro zone and make the game thing that there wasnt any active zones
