How to make lift/inferno-style doors in Doom Builder X/2/UDB

[Frost-Core]

Ever wanted to make a door like the ones in inferno or a lift? (doors that open from the bottom and not the top) well i can show you how to! with images of course! :

Step 0 : Before we even start we need to own doom of course, the games you need are just

The Ultimate Doom (or maybe even registered doom) (optional if you want episodic structure, also make your map name ExMy)

Doom II : Hell On Earth (recommended game)

if you can't buy these games, i recommend you get freedoom

also get Doom Builder, I recommend Ultimate Doom Builder Or Doom Builder X, here is where you can get them :

UDB :

Doom Builder X :

If you are classic get the original Doom Builder 2 :

http://www.doombuilder.com/

Step 1 : Create a new doom builder map and change some of the settings, if you want boom format then select it, in this example we will be making MAP02 our new map, and its gonna be in doom 2 format, here is what you have to do :

notice that resources thing there? click add resource and locate the game's wad file (should be doom2.wad, doom.wad or freedoomx.wad)

Step 2 : Click OK, now right click to draw a room, we need to draw two rooms seperated by 32 in the grid, here is an example :

Step 3 : draw between the little space that we made a line thats 32 long and 128 tall, and go to visual mode by pressing w and set its walls as "Upper Unpegged" this prevents the door from moving along with its walls, and also make sure to set it as a nice texture like DOORTRAK, replace the wall's textures (the wall that we put and changed its height) to a nice door texture like BIGDOOR2, also add a player 1 start to put where the player is going to start. go to things mode and right click on a space in the rooms, and select player starts -> player 1 start.

NOTE : to change textures, go to visual mode and right click the ones with exclamation marks, and go to the sidedefs section and click the exclamation mark, it would show you a window so search for BIGDOOR2.

NOTE 2 : use the scroll wheel on the space we made in visual mode to change its height, and use the ESDF keys to move around

here is an image of what it would look like after we did that :

Step 4 : If you save it and run it with the game it would not work, this is because we have not given it a tag and action, press w to exit out of visual mode and select it with "Sector Mode", right click on it and click new tag, or just type 1, now select the linedefs (the little lines in the non visual view) that the player is going to use to open the door, set them to the same tag and give them an action, find it in lifts and select S1 Lift Lower Wait Raise, S1 means switch once, if you want to do it every single time and not just once, select SR Lift Lower Wait Raise, also there are fast versions if you want the door to be faster, now exit out of that window and save the game and launch it, boom! now you have a working door!

Step 5 : If you want a lift make the room you want to go to higher.

Step 6 : We ran out of steps, this is because you are done! now show it off to your friends and they'll be amazed!

You probably should have labelled this tutorial as a lift tutorial instead of an inferno-style door tutorial as more new mappers will be searching for lift tutorial.
