Concept
LPMud
Résumé
LPMud, abbreviated LP, is a family of MUD server software. Its first instance, the original LPMud game driver, was developed in 1989 by Lars Pensjö (hence the LP in LPMud). LPMud was innovative in its separation of the MUD infrastructure into a virtual machine (known as the driver) and a development framework written in the LPC programming language (known as the mudlib).
Lars Pensjö had been an avid player of TinyMUD and AberMUD. He had wanted to create a world with the flexibility of TinyMUD and the style of AberMUD but did not want to have sole responsibility for creating and maintaining the game world. He once said, "I didn't think I would be able to design a good adventure. By allowing wizards coding rights, I thought others could help me with this." The result was the creation of a new, C-based, object-oriented programming language, LPC, that made it simple for people with minimal programming skills to add elements like rooms, weapons, and monsters to a virtual world.
To accomplish his goal, Lennart Augustsson convinced Pensjö to write what today would be called a virtual machine, the LPMud driver. The driver managed the interpretation of LPC code as well as providing basic operating system services to the LPC code. By virtue of this design, Pensjö made it more difficult for common programming errors like infinite loops and infinite recursion made by content builders to harm the overall stability of the server. His choice of an OO approach made it easy for new programmers to concentrate on the task of "building a room" rather than programming logic.
Pensjö created Genesis in April 1989 as the first implementation of the LPC language, and therefore the first LPMud, in which the developer (commonly known as a wizard within the MUD) could code their own objects.
Pensjö's work has been extended or reverse engineered in a number of projects:
LPMud 3.2, better known as the Amylaar driver, after its lead developer, Jörn "Amylaar" Rennecke
MudOS
DGD, Dworkin's Game Driver, a conceptual rather than code derivative of LPMud developed by Felix "Dworkin" Croes
SWLPC, Shattered World's fork of LPMud 2.
