A dialect of the BASIC programming language, BlitzPlus was designed with ease of use in mind, particularly for beginners and aspiring game developers. Its features, which include a simple and intuitive syntax, made it an ideal entry point for those looking to create their own games without delving into the complexities of more advanced languages. Over time, BlitzPlus evolved to support more advanced features, making it relevant for both hobbyists and more experienced developers.
This article explores the history, features, and impact of BlitzPlus, highlighting how it contributed to the landscape of game development in the early 2000s and beyond.
The Origins of BlitzPlus and Blitz Programming
BlitzPlus is part of the Blitz family of programming languages, which were developed by Mark Sibly, a New Zealand-based software developer. BlitzPlus was first introduced in 2003 as a successor to Blitz BASIC, one of the earliest game development tools designed for ease of use. Blitz BASIC was derived from the original BASIC programming language, which had been designed in the 1960s for educational purposes and ease of learning.
Mark Sibly’s goal with Blitz BASIC was to make a programming language that could be easily picked up by beginners yet still powerful enough to create games. He focused on maintaining the simplicity of BASIC while incorporating features specifically aimed at game development. BlitzPlus built upon these principles, expanding on the capabilities of its predecessor and adding new features like advanced graphics support, sound management, and more sophisticated game development tools.
BlitzPlus, in particular, was designed to provide developers with the tools necessary to create 2D and simple 3D games. While many programming languages at the time required developers to have in-depth knowledge of game mechanics and graphics programming, BlitzPlus made this process far more accessible. By abstracting away some of the lower-level complexities of game programming, BlitzPlus enabled developers to focus more on creative aspects like game design and gameplay mechanics.
Key Features of BlitzPlus
BlitzPlus shared many characteristics with other dialects of BASIC but stood out due to its specific focus on game development. Below are some of the key features that made BlitzPlus unique:
1. Simplicity and Accessibility
One of the hallmark features of BlitzPlus was its simplicity. It was designed to be easy to learn, particularly for individuals who were new to programming. The syntax was straightforward, with many of the same conventions as BASIC, making it an ideal starting point for beginners. Developers could write programs using plain English-like statements, which made the language approachable for a wide range of users.
2. Game-Oriented Features
BlitzPlus was specifically designed with game development in mind. The language featured built-in commands for handling graphics, sound, input devices, and other multimedia elements that were essential for creating interactive experiences. Developers could easily draw graphics on the screen, manage animations, and integrate sound effects and music into their games.
3. 2D and Simple 3D Graphics Support
BlitzPlus provided strong support for 2D game development, with simple commands to draw shapes, images, and manipulate objects. As the language evolved, BlitzPlus also began to support basic 3D graphics, including 3D objects, transformations, and rendering. Although it was not as powerful as more modern game engines, BlitzPlus allowed developers to create simple 3D games, making it a valuable tool for independent developers and hobbyists.
4. Integrated Development Environment (IDE)
BlitzPlus came with an integrated development environment (IDE) that facilitated coding, debugging, and testing. The IDE featured syntax highlighting, error detection, and quick access to relevant documentation. This made development more efficient and helped developers learn the language more quickly.
5. Event-Driven Programming Model
Like many game development environments, BlitzPlus used an event-driven programming model. Developers could set up different game events (e.g., collisions, key presses, mouse clicks) and define what actions should take place when these events occurred. This event-driven approach was essential for interactive applications like games, where the program needed to respond to user input and other stimuli.
6. Cross-Platform Support
BlitzPlus was designed to work on multiple platforms, including Windows, which was the primary operating system at the time. This made BlitzPlus a versatile option for developers looking to create games that could run on a variety of devices, though it did not have the same level of cross-platform support as some of the more modern game development tools.
7. Object-Oriented Programming (OOP)
As BlitzPlus evolved, it began to incorporate object-oriented programming (OOP) features. OOP allowed developers to create more structured and modular code by organizing data and functions into classes and objects. This made it easier to manage larger projects and add more complex game features. While BlitzPlus never fully embraced OOP like languages such as C++ or Java, it provided basic support for classes, inheritance, and polymorphism, giving developers more flexibility in their code structure.
The Evolution of BlitzPlus and the Rise of More Advanced Tools
While BlitzPlus was popular in the early 2000s, it eventually began to be overshadowed by more advanced game development tools. As game development evolved, so too did the requirements for more complex and powerful game engines. Languages like C++, C#, and later engines such as Unity and Unreal Engine became the standard for game developers due to their robust features and flexibility.
However, BlitzPlus remained relevant for a period, particularly among indie game developers, hobbyists, and educational institutions. Its simplicity and accessibility continued to make it a viable choice for those who wanted to experiment with game development without diving into more complicated programming languages.
BlitzPlus’ evolution also paved the way for later programming languages that combined the simplicity of BASIC with the power of more advanced features. For instance, BlitzMax, a successor to BlitzPlus, added even more advanced capabilities and support for 3D graphics, multimedia integration, and cross-platform development. While BlitzMax itself did not achieve mainstream popularity, it marked the next step in the Blitz programming language family’s attempt to cater to the needs of developers who wanted both simplicity and power.
Community and Legacy
Despite its decline in widespread use, BlitzPlus developed a strong community of dedicated users. Forums, tutorials, and user-created content played a major role in supporting new developers and fostering the growth of small indie games. The community aspect was one of BlitzPlus’ defining features, with many users sharing tips, tricks, and code snippets to help each other overcome common programming challenges.
The legacy of BlitzPlus can still be seen in some of the tools and languages that emerged in the years following its introduction. For example, the simplicity of BlitzPlus influenced several modern game development platforms that aimed to reduce the barriers to entry for aspiring game developers. Furthermore, the emphasis on event-driven programming, as well as built-in multimedia support, was ahead of its time and can be found in modern engines such as Godot and GameMaker Studio.
BlitzPlus also left an imprint on the educational realm, where it served as an introduction to game development for many budding programmers. Its intuitive nature and focus on creativity over technical complexity allowed students and hobbyists to learn basic programming concepts while also engaging in the fun, interactive world of game creation.
Conclusion
BlitzPlus represents a unique chapter in the history of game development, serving as a bridge between the simplicity of BASIC and the complexity of modern game engines. By providing an accessible, game-focused programming language, it helped countless developers—particularly those just starting their journey—dive into the world of game creation. While it may not have the widespread recognition of larger game development engines today, its impact on the early 2000s indie game development scene cannot be understated.
Whether it was used for creating simple 2D games or experimenting with rudimentary 3D graphics, BlitzPlus empowered a generation of developers to explore their creative potential. Though the language itself has largely faded from the spotlight, the principles that made BlitzPlus successful—simplicity, accessibility, and a focus on game development—continue to influence new programming languages and game engines in the present day.
