Highrise
by Wurzzie
Created April 19, 2020 for Snap the Sentinel v2.4
This is my first (coherent) map for Snap and for Doom modding at large! It was a learning experience the whole way and it is something I’m quite proud of! Highrise is a cut-and-dry challenge map, see if you can make it the whole way! The par time is about four minutes and takes place on a massive elevator, so expect cramped spaces and a dire need of spatial awareness!
While the map is largely uneventful, being in one location and basically just being waves until a boss, the neat stuff I think that’s worth mentioning is all behind the scenes. The starting platform never moves, the entire map moves around it. I implore you to play this map and then go in again with god mode enabled so you can watch the horizon as the elevator ascends. It’s a neat trick I pulled off, I cheated a fake vertical parallax, so the buildings, the horizon, they all move down instead! I also made the city in a series of concentric circles, rather than square blocks, which helped it look more…city-like? It also helped reinforce that the elevator you’re on is at the city center! Very important for sure, where it came from, why it’s there, I have no idea!
There’s also a lot of fun coding trickery to make what should be a simple map tick! Don’t be afraid to pick the map apart, I encourage it! Thank you for playing my map, don’t hesitate to let me know of any glitches or thoughts on the map!

Created December 15, 2020 for Snap the Sentinel v2.4
Snap explores some dangerous volcanic ruins, and gets attacked from all directions! Look out for a few secrets, and watch out for the challenging multi-part enemy encounter near the end of the stage! This was a map I made to test Ultimate Doom Builder and it's my first Snap level, but I think it turned out pretty fun.

Create Your Own
File Editing
SLADE3 (Windows, Mac, Linux)
For basic file editing, we recommend SLADE3, a powerful lump management tool.
- Install the version for your operating system, then open SLADE..
- Click the "New Archive" button, select either "Zip Archive" (for modern PK3s) or "Doom WAD Archive" (for classic WADs), then press "Create" to instantly create a new mod!
- Or, click the "Open" button to start peeking into snapgame.ipk3 or other mods.
- Most modding information can be found at the ZDoom Wiki!
Mapping
Ultimate Doom Builder (Windows)
Ultimate Doom Builder is our recommended map editor, but only officially distributes Windows.
(UDB can work on Linux as well, but compiling is very DIY.)
- Download and extract Ultimate Doom Builder.
- Extract the contents of UDBConfig within SnapMappingConfigs (included with Snap the Sentinel) into UDB's "Configurations" folder.
- Open UDB, go to "Tools -> Game Configurations".
- Hit the checkbox next to "GZDoom: Snap the Sentinel (UDMF)" to enable the Snap config.
- Under the Resources tab, add the path to "snapgame.ipk3". Be sure to check "Exclude this resource from testing parameters" when adding, or you'll recieve an error message when testing.
- Under the Testing tab, add the path to "gzdoom.exe".
- Ultimate Doom Builder is now prepped to create Snap maps! Hit "File -> New Map" and select the Snap the Sentinel Game Configuration to start creating. Check out other UDB tutorials for more info.
SLADE3 (Windows, Mac, Linux)
SLADE3 has its own very good map editor as well that supports more systems, but takes a lot more advanced set-up to get working for Snap than UDB.
- Install SLADE3.
- Launch SLADE3, open the "slade.pk3" file with it in your SLADE installation folder. (Crazy, I know!)
- Put the contents of SLADEConfig within SnapMappingConfigs (included with Snap the Sentinel) into slade.pk3's "config/games" folder.
- In the "config/port/zdoom.cfg" file, search for the "Supported games" line, and add "snap" to the end of it.
- Save slade.pk3, and then restart SLADE.
- SLADE is now prepped to create Snap maps! Hit the "Map Editor" button, set Game to "Snap the Sentinel" and Port to "ZDoom", and you can start creating. Check out other SLADE tutorials for more info.
