4. Solo Development: A Different Approach

When working solo, the mindset shifts. Zylinski notes that the approach to making games at 35 is more similar to the one he had around age 19 than the approach he learned from working in the games industry. Instead of focusing on building a general-purpose engine with shiny tools, prioritize gameplay.

4.1 The Pitfalls of Building a General-Purpose Engine

It’s tempting to build a general-purpose engine before writing gameplay code. You might find yourself creating renderers, level editing tools, file formats, and data compilers. However, this can lead to a lack of progress on the actual game.

4.2 Back to Basics: Odin and Raylib

Zylinski found a winning combination with the Odin Programming Language and Raylib. Raylib is a library similar to SFML, but written in C. Odin comes with built-in bindings for Raylib. This combo allowed him to quickly get stuff on the screen without the overhead of data-heavy third-party engines.

4.3 Advantages of This Approach

Focus on Gameplay: You can put as much stuff in code as you want, without dependency on data created within game engine tools.
Code over Data: Favor procedures with parameters for creating game objects over complex editors.
Efficiency: Avoid creating tools you don’t need.

4.4 The Solo Developer Mindset

As a solo developer, your needs are different than those of a team. You don’t need to create tools to empower others. Instead, focus on tools that genuinely aid your creation process. Put as much as possible in the code.

4.5 Why Odin Over C++?

While Zylinski initially used C++, he found Odin to be more efficient. C++ can be a bit too verbose, creating friction when adding new features. Odin’s code is more compact and simpler, making it easier to overcome the mental hurdle of adding new features.

5. Tips for Game Development Success

Here are some tips to help you succeed in game development:

Start Small: Don’t try to create a massive game as your first project. Start with a small, simple game that you can finish in a reasonable amount of time.
