Level editor

This article or section is a stub. Please help the Doom Wiki by adding to it.

A level editor (alternatively called a map editor or rarely a mission editor) is an editing utility, typically with a GUI, that is used to create levels.

History[edit]

id Software's DoomEd level editor running in NeXTSTEP OS.

In-house level editors[edit]

id Software used the in-house DoomEd level editor during the development of Doom and Doom II. It was also used by Raven Software for Heretic and Hexen.

Midway Games developed an in-house level editor called DEX to create levels for Doom 64.

During the development of Doom 3 id Software used Doom 3 Radiant level editor, that was based on Q3Radiant level editor used for Quake III Arena. Doom 3 was released bundled with the editor.

The idStudio editor was used in the development of Doom Eternal.

Fan-made level editors[edit]

The original Doom gained a huge following among fans. Since DoomEd was not publicly released at the time, it was only a matter of time before fan-made modding tools would appear. Doom Editing Utilities (DEU), the first third-party level editor for Doom, was released on January 26, 1994, just a month and a half after the game's release. Many other level editors were released in the following years, but not all of them were free. As the complexity of utilities increased, some of them became paid. Usually, a cut-down free version was released, and paid registration was required to get full functionality. Nowadays, most Doom level editors are free, and their source code is usually available for study and modification.

Features[edit]

Modern level editor usually has the following features:

a graphical user interface (GUI);
several built-in game configurations for different map formats (such as Hexen format or UDMF);
several modes that allow to create level geometry, apply textures, place things;
a 3D or visual mode that allows the user to see the level close to how it will look in-game;
one or more built-in node builders;
an ability to test the level in the preferred source port.

Early classification[edit]

Early level editors were classified as follows:

in line-based editors the level was constructed using linedefs (lines);
in sector-based editors the level was constructed using sectors;
mode-based editors had several operating modes (for example to work with lines and sectors).

The vast majority of modern editors have all these capabilities.

Level editors for Doom (2016)[edit]

Doom (2016) has the built-in level editor called SnapMap. There is also a fan-made utility called SnapHak that can be used to unlock normally unavailable features of SnapMap.

Level editors for Doom Eternal[edit]

Since its release in March 2020, Doom Eternal has not had an official level editor. Community members had to use workarounds to create levels for the game. This problem was finally solved in August 2024 when id Software released DOOM Eternal: idStudio.
