LPC is a programming language used in games, created by Lars Pensjö to make crafting items and blueprints in MUDs more accessible. It mirrors C but doesn’t have strongly typed variables, allowing users to create objects. LPC is comprehensive and stable, making it easier for new programmers to focus on building things. Objects are defined in centralized files, making code easier to write and maintain. LPC has been used for other purposes, including the creation of the Pike programming language for multimedia applications, system administration tasks, and internet servers.
LPC is a computer programming language used primarily in games, but which also has applications in other settings, perhaps most notably as the basis for the Pike language. It was developed by Swedish computer scientist Lars Pensjö, which is where the “LP” part of the name comes from. The “C” comes from the C language, from which it derives. C is one of the most common programming languages, and many different platforms and programs have been built on its back. Pensjö created his program at least in part as a way to more effectively craft items and blueprints in multi-user dungeons (MUDs), which are an aspect of several online gaming platforms. One of the most distinctive features of this language is that it allows players to type commands with more or less natural wording, and a number of different gaming platforms use its core syntax and specifications. While it tends to be more popular within the gaming community, it has also found a number of uses elsewhere in the world of open source coding.
Original start and purpose
MUDs are popular parts of a couple of different mainstream online gaming platforms. Players from anywhere in the world, anywhere with an Internet connection, that is, can meet, usually in the person of an avatar, and exchange information, fight, or create items with each other via coded controls. Anyone playing a multi-user game like this typically needs at least a basic understanding of coding and command syntax in order to engage. The simpler C-based format was designed primarily to make that part of the game more accessible.
Basic syntax
The basic syntax of any coding language is the system used to generate lexical and syntactic parsers. In the simplest terms, they are the nuts and bolts of how coding is done, written, and received by hosts. In many key respects, LPC mirrors the C language, but does not have strongly typed variables. This allows you to use it to create objects instead of items. For example, in a dungeon environment, rooms, weapons, monsters, and armor are items. The programming language allows users to create, modify, delete and reproduce these objects in almost any way they like.
Programming specifications
In general, the language supports many different types of programming, including procedural, modular, structured, object-oriented, defined, and weak variable data, making it a comprehensive and all-encompassing computer language. A key feature of Pensjö’s design is its relative resistance to common coding mistakes by content creators. The overall stability of a server is almost always improved even with this language in use, which can allow new programmers to focus on the task of building things rather than being consumed by the programming logic itself.
Role of projects
While almost everything is an object in LPC, it doesn’t use the concept of classes. Instead, an object in this setting is a project object or a clone of a project object; while technically different from a class, these projects can often be treated the same. All attributes and methods can be accessed at the instance and class level in this language which is not always the case in other object oriented languages which allow them to be restricted to class and instance.
Relation of objects to the central file
In LPC code, common objects are defined in centralized files. When several game “rooms” are created, they inherit objects from the central file, and as a result, a change to that file will also affect every piece of code where that object is used. This avoids the need to code each of these objects in every location, making the code easier to write and maintain. This centralization isn’t unique, but it’s part of what makes it possible to create complicated games with this programming language.
Flexibility and other uses
The flexibility of the code as a whole has led to it being used for a variety of purposes other than creating the MUD game. Wide-ranging uses include the creation of the Pike programming language, which is based almost entirely on Pensjö’s model. Pike is widely used for multimedia applications, system administration tasks and Internet servers.
