From your text it is not clear what you have in mind and what map format you use.

 

In DOOM/2 the only way to apply 3 different keys to doors is :

• either 3 doors in sequence as in Halls of the Damned

 

 

• or 3 blocking walls in sequence

 

 

Attaching up to 6 keys to a door was introduced in BOOM, eg:

 

 

and carried over in more advanced doom ports, eg:

 

 

As for the door moving down slightly it would be best if you posted the map.

It is only in advanced ports that you can apply 3 keys to a single door

i am using gzdoom and ultimate doom builder and im trying to make it so you have to use all 3 keys on 3 small doors before accessing a switch to open a door

Don't have you're doors touching each other. Space them apart at least 17 units.

Also looks like you have to flip that 4th linedef from below since it seems to have an action. If it's a door or a switch it won't work like that.

Also if you are going to stack doors like that, you should not add effects on the back side. Any kind of line between you and the switch blocks use key, unless it used to be single-use and now exhausted.

Not entirely true. Boom does have generalized line actions that allow making a door require all three keys. Or even six if you set the Combination "flag" to False.

[Aurelius]

Doors function by raising the sector's ceiling 4 map units below the lowest adjacent ceiling, meaning that if your doors are back to back touching like that, they will not open as intended (as they will act as the lowest adjacent ceiling to each other). So to sum up what everyone has said:

• Leave wide enough (>17 map units) gaps between doors so that the line activation isn't blocked and the doors aren't adjacent.
• Have the front side of each sidedef with a line action point to the direction you want the door to be opened from. In other words, don't have them pointing into the door.

It appears that your doors are right next to each other and touching (3 or 4 doors, it is difficult to see from the image).

That will not work, leave some space between each door

 

 

The best way to make a door is with the build-in routine Make Door (Shift+D)
