'''Boom''' is a [[source port]] created by [[TeamTNT]]. The design goals of the Boom project were to create a source port of professional quality, fix bugs and remove limitations of [[vanilla Doom]], and add extra editing features, while keeping the same "feel" and "spirit" of the original Doom engine. The final version of Boom was released on October 22, 1998. The source code for Boom was released in October 1999.

Boom itself only ran under MS-DOS and was developed using {{wp|DJGPP}}, the DOS port of gcc. The code was later ported to other operating systems.

Boom can be viewed as a much more conservative source port than some others because of its strong emphasis on maintaining the original feel of the Doom engine. While many contemporary source ports concentrated on adding ''[[Quake]]''-like features (such as a [[console]], restructuring menus, or adding impressive new graphical features), Boom behaves very similarly to the original Doom executable. Many of the changes made in Boom are not immediately visible, such as the removal of limits (e.g. the [[visplane limit]] error) and the addition of editing features which, while immensely useful to level designers, may not be obvious to the player.

A large number of [[WAD]] files have been developed which require Boom to run. Because of the attractive editing features provided by Boom, many popular source ports have adopted support for these features. This has led to the term "[[:Category:Boom compatible|Boom-compatible engine]]": such WADs may run on many different source ports provided that the source port used supports the Boom editing extensions.

== Features ==
* Removal of engine limits and bugs. This includes the [[visplane limit]], the [[tutti-frutti effect|tutti-frutti]] and [[Medusa effect|medusa]] effects, the [[savegame buffer overflow|savegame size limit]], the [[venetian blind crash]], and many others.
* Optimizations to the engine.
* New editing features. These include:
** Configurable [[ANIMATED|animated]] and [[SWITCHES|switch]] textures.
** [[Deep water]] effects.
** Scrolling walls, floors, and ceilings, including support for [[conveyor belt]]s.
** [[Translucency|Translucent]] walls and [[sprite]]s.
** [[Friction]] effects, such as mud and ice.
** Custom [[colormap]]s (which can provide, for example an underwater blue "tint").
** Silent [[teleporter]]s, which can be useful for fake "room over room" effects.
** [[Elevator]]s which move the floor and ceiling of a sector together.
** Generic [[linedef]] types - a particular linedef behaviour can be "calculated" using a separate linedef calculator program called {{c|TRIGCALC.EXE}}.
** A [[DeHackEd]] extension standard, [[BEX]].

== Authors ==

The primary authors of Boom were:

* [[Jim Flynn]]
* [[Stan Gula]]
* [[Ty Halderman]]
* [[Lee Killough]]
* [[Rand Phares]]

== Derived source ports ==

After the Boom project ended, several source ports arose which were derived from the Boom source code. These include:

* [[LxDoom]], which later merged with [[PrBoom]], a portable version of Boom.
* [[MBF]], [[Lee Killough]]'s continuation of his work on the Doom engine.
* [[Steve Boom]], initially meant as a learning experience, it became a port of its own, based on Boom 2.01.
* [[PrjDoom]], the successor of Steve Boom, based on Boom 2.02.
