SnapMap

The blueprint mode in SnapMap, where modules can be added or manipulated.

The object mode in SnapMap. Interacting with this panel triggers logic to end the level.

SnapMap is the integrated editor in Doom (2016) that allows players to create and edit maps with their own structure and game logic. It can be used to assemble prefabricated rooms, place objects such as monsters and weapons, and define custom events within maps. Players can create maps for different modes, ranging from single-player levels, to co-operative or competitive multiplayer maps. When building a level, the game will shift to a top-down view where players can place pre-defined rooms and hallways to form a level. Additionally, they can make custom areas using blocking boxes or decorations. Players can also access the X-ray camera, which temporarily removes all the walls to allow players to view the objects inside.

Most of the game's enemies can be placed in SnapMap normally, with the exception of the summoner and campaign's bosses. Their artificial intelligence and stats, and the player's own movement speed, can also be modified. Players can also add additional particle effects, lighting effects, and other gameplay items like health packs and ammo pick-ups into their creations. Only in-game assets can be used; it is not possible to create or import custom models into the game. However, custom geometry can be crafted to a degree through clever use of clip volumes and placement of static props, the use of which became significantly more flexible as the editor was updated. Levels can be tested before they are published online.

For players who do not wish to create extensively, the game features an AI conductor which automatically generates enemies. Players will receive "snap points" after they create a level or play a level created by other users. These points can be used to unlock additional cosmetic items. Players can share their completed maps with other players. They can upvote or downvote maps, and can utilize other players' content as a base and share the results while citing the originals' authors. Maps can be permanently downloaded so that they remain available while offline.

Features

Modules

Modules are the most basic building structures of SnapMap, pre-built rooms from which everything happens inside. It is not possible to place anything or go outside of modules without the use of hacks or glitches. There are between 2 and 8 entrances that allow modules to connect to each other, there are four themes in which modules fit:

• Industrial (based on Resource Operations and Foundry)
• Hell
• White collar (based on Lazarus Labs and VEGA Central Processing)
• Classic (based on Knee Deep in the Dead)
• Transitions (adaptors to connect modules with different themes)

Logic nodes

Logic nodes are the units which make up SnapMap's own visual programming language. Everything that happens from the map's start to the end is done through nodes, they can connect to objects and other nodes for a multitude of effects.

Templates

Templates are example maps that users can start from to make their own, they feature basic logic and a few objects placed on it, there are nine templates in total and a few official maps made for each:

• Basic
• Classic
• Classic deathmatch
• Capture the Flag
• Extraction
• King of the hill
• Survival
• Team deathmatch
• Tiny
