What game development taught me about coding

This blog post is based on my book “How to Code Any Feature”.

My coding journey began with C++ game development. For nearly two years, I worked full-time on hobby games, from small projects to larger independent games. Some were released, while others stayed as private projects. Each one made me deal with features, broken behavior, and code that had to keep fitting together.

Every game needed its own features, so I had to think about structure and performance instead of treating code as isolated exercises. That was where data structures and algorithms started to feel practical. The choice of an approach could affect how the game behaved.

Debugging was another constant. Different projects brought different problems, and working through them made me better at finding the cause instead of guessing at a fix.

Competitive coding trained a different part of the same skill. Sorting numbers in an array did not look much like building an independent game, and some problems felt impractical. Still, those exercises made me more comfortable breaking a large problem into smaller ones.

The part that stayed with me was how much interest changes the work. When I cared about the game, I was willing to keep working through a problem that would have felt tedious somewhere else. Enjoyment did not replace technical skill, but it helped me stick with the hard parts.

Game development gave me a practical way to learn coding. Competitive coding gave me sharper practice with smaller problems. Together, they shaped how I approach programming.
