I have a Der reise style map that loops with my zones set
doors in place with triggers on each side of each door with kvps only changed for the enter_zone_[filler] for each side depending whether you go right or left
my issue is my door can only target the set of spawners one way since the target is set by the door and not the trigger
ie door2 going right= target:zone_2_spawners
but what if i wanted to go left opening the door from the other side triggers the spawners from the zone i'm leaving
how can i make door2 [going right it targets zone_2_spawners] target zone_1_spawners if I'm going left but still target zone_2_spawners if bought from the right

my only guess is removing the function from the door and moving it to a separate trigger overlapping my buy trigger on each side targeting the spawners in said direction.

Let's say you want to go from the kitchen to the hall and the other way around, you should then add this in your mapname.gsc in your dlc3_zone_init function:

add_adjacent_zone( "kitchen", "hall", "enter_kitchen_hall" );
add_adjacent_zone( "hall", "kitchen", "enter_kitchen_hall" );

That should do it.

i've got adj zones covered but my door only triggers the spawners ahead of me if i go right, if i go left then the spawners are triggered in the room i'm already in when i open that same door from the other side on a seperate playthrough

i think i've figured out my issue
 i really don't even need the door to target spawners cause that was the old way of doing it
  in a der reise style map its all covered by zoning
 you do have to be careful about putting your triggers too close to the door though
cause you can trigger both sides and mess up spawns
