How can I learn game programming fundamentals without getting overwhelmed?
|
I'm a student trying to learn game development, and I keep hitting a wall when it comes to understanding game programming fundamentals. There are so many free game programming tutorials out there, but they all seem to assume different levels of prior knowledge.
What I really need are first game creation tutorials that focus on the core concepts rather than just showing me how to make a specific game. I want to understand things like game loops, collision detection, state management, and other game development basics. But every time I try to learn, I get overwhelmed by the complexity.
Has anyone found a good approach to learning game development from scratch that builds up knowledge gradually? I'm looking for game development projects for beginners that actually teach the underlying principles, not just how to copy code. Any recommendations for resources that helped you build a solid foundation?
I struggled with this exact problem for months before finding an approach that worked. The key is to separate learning programming fundamentals from learning game-specific concepts.
Start with Harvard's CS50 course (free online). The first few weeks cover programming basics in a way that's accessible and well-structured. Once you understand variables, functions, loops, and conditionals, game programming becomes much more approachable.
For game-specific concepts, I'd recommend starting with a framework rather than a full engine. Something like Pygame (Python) or Love2D (Lua) forces you to implement basic game systems yourself. Following tutorials for these frameworks will teach you game development from scratch - you'll implement your own game loop, handle input, manage game states, etc.
The book Invent Your Own Computer Games with Python" is free online and perfect for this. It walks you through creating simple games while explaining the underlying concepts. This foundation makes engine-specific tutorials much more understandable later.
What helped me was focusing on one concept at a time rather than trying to learn everything at once. Game programming fundamentals can be broken down into manageable chunks.
Week 1: Learn about game loops and timing. Make a simple program that updates a counter 60 times per second.
Week 2: Learn about input handling. Make a program where you can move a dot around the screen with keyboard or mouse.
Week 3: Learn about basic collision detection. Make a simple game where a player collects items.
Week 4: Learn about game states. Implement a menu screen and game over screen.
There are free game programming tutorials that focus on each of these concepts individually. The trick is to not jump ahead until you feel comfortable with each piece.
I'd also recommend using an environment with immediate visual feedback. Processing (processing.org) is perfect for this. You write simple code and see immediate results, which helps build understanding. Their tutorials are excellent for learning programming concepts through visual applications.
The overwhelm usually comes from trying to learn too many things simultaneously. Here's a structured approach that worked for me and several friends:
1. First, learn basic programming with a non-game focus. Complete Codecademy's free Python course or similar. This gives you programming fundamentals without game complexity.
2. Next, learn basic math concepts needed for games: vectors, basic trigonometry, and algebra. Khan Academy has free courses on these.
3. Then, start with a simple game framework. I recommend Love2D with the CS50's Introduction to Game Development" course (free on YouTube). This course is amazing because it builds up concepts gradually.
4. Only after completing a few small games with a framework should you move to a full engine like Unity or Godot.
The mistake most people make is jumping straight into Unity/Unreal tutorials. These engines have so many features that beginners get lost. By starting simple, you build a foundation that makes the complex engines understandable.
For game development projects for beginners, think "Pong, then Breakout, then a simple platformer." Each builds on the previous one's concepts.
