Jedi is a game engine developed primarily by Ray Gresko for LucasArts. [3] It is very similar to the Build engine used in Duke Nukem 3D . While not a true 3D engine, it supported a three-dimensional environment with no limitations in the 3rd dimension (Z). In Doom , environments or levels were limited to existing in the X-Y plane only – levels were laid out two-dimensionally: while floor and ceiling heights could differ, areas could not overlap vertically. The Jedi Engine had support for areas or rooms (called "sectors") on top of one another, a trait that it shared with the Build engine. [2] In the Dark Forces revision of the engine, the renderer could not display two rooms situated on top of each other simultaneously. This capability was added for Outlaws . [4]

The Jedi Engine also included the ability to jump and crouch, the ability to look up and down, [3] and atmospheric effects (achieved by careful manipulation of 256-color palette files). [5] The engine is limited in its rendering capabilities, however, and used two-dimensional sprites (pre-rendered in different angles) for most of its object graphics. [4] Other LucasArts techniques such as the iMuse sound system were incorporated. [1]

Its lifetime was short-lived, being used in two titles, Star Wars: Dark Forces and Outlaws . [6] The sequel to Dark Forces, Jedi Knight , used the Sith engine.

There have been attempts of open source game engine recreations based on reverse engineering the original source code. [7]

Lucasfilm Games is an American video game licensor that is part of Lucasfilm. It was founded in May 1982 by George Lucas as a video game development group alongside his film company; as part of a larger 1990 reorganization of the Lucasfilm divisions, the video game development division was grouped and rebranded as part of LucasArts. LucasArts became known for its line of adventure games based on its SCUMM engine in the 1990s, including Maniac Mansion, the Monkey Island series, and several Indiana Jones titles. A number of influential game developers were alumni of LucasArts from this period, including Brian Moriarty, Tim Schafer, Ron Gilbert, and Dave Grossman. Later, as Lucasfilm regained control over its licensing over the Star Wars franchise, LucasArts produced numerous action-based Star Wars titles in the late 1990s and early 2000s, while dropping adventure game development due to waning interest in the genre.
