When to Use Examples Instead of Exposition in Tutorials

When to Use Examples Instead of Exposition in Tutorials

I used to think good tutorials meant exhaustively explaining every single concept upfront. I’d meticulously research, write pages of theory, and then… silence. No one finished them. They were walls of text that scared people away. I was so focused on being comprehensive that I forgot the point: to help people do something.

Lessons learned from veteran indie developers taught me that examples are the key to unlocking understanding, especially when working with engines and code.

Ditch the Info Dump: Show, Don’t Tell (Initially)

The biggest mistake I see beginner tutorial creators make is front-loading everything with exposition. Imagine learning to ride a bike by first reading a 50-page manual on the physics of balance, the mechanics of pedals, and the history of bicycle manufacturing. You’d be asleep before you even saw the bike.

Game development is the same. Throwing a barrage of terms, concepts, and abstract ideas at learners before they’ve even seen anything concrete is a recipe for confusion and frustration. This is doubly true when targeting other solo developers who want to learn specific techniques as quickly as possible!

Instead, start with a working example. Let them see the result of what they’re about to learn. This provides immediate gratification and context for the explanations that follow.

The Power of “Hello, World!” and Beyond

Think of the classic “Hello, World!” program. It’s not just a tradition; it’s a brilliant teaching tool. It immediately shows a simple, functioning program. This allows the learner to get that rush of dopamine when the project compiles, and THEN they can start to learn what each line means.

Extend this principle to more complex concepts. If you’re teaching AI pathfinding, don’t start with A* algorithm theory. Start by showing a character navigating a maze. Let the learner play with it, tweak parameters, and observe the behavior. Then delve into the underlying mechanics.

Break it Down: From Example to Explanation

Once you’ve presented a working example, break it down piece by piece. Explain the core principles demonstrated in the example. Focus on what’s essential for understanding that specific example.

Avoid the temptation to explain every single related concept at once. This leads to information overload and distracts from the main learning objective. One technique is to make the first explanation fairly high-level, but include links to more advanced material for folks who want to dive deeper.

For code snippets, annotate liberally. Explain what each line does, but more importantly, why it does it. Focus on the intent and the relationship between different parts of the code.

Hands-On Learning: Modification and Extension

Learning isn’t passive. It requires active engagement. After explaining the core principles, offer opportunities for hands-on modification and extension.

Suggest simple changes that learners can make to the example to see how they affect the outcome. What happens if they change a variable? What if they add a new object?

Challenge them to extend the example by adding new features or functionalities. This encourages experimentation, problem-solving, and deeper understanding. This helps solidify their knowledge and helps them learn how to solve novel problems on their own.

Common Pitfalls and How to Avoid Them

• Unexplained Code Snippets: Presenting code without adequate explanation is just as bad as pure exposition. Always explain what the code does and why.
• Overly Complex Examples: Start with simple examples that focus on a single concept. Avoid overwhelming learners with too many moving parts.
• Lack of Interactivity: Don’t just show; let learners interact with the example. Encourage experimentation and modification.
• Ignoring Errors: Don’t shy away from showing potential errors. Explain how to troubleshoot common issues and provide debugging tips.

The Importance of Tracking Your Progress

As you work through tutorials and create your own game, it’s crucial to track your progress. This isn’t just about ticking off tasks on a to-do list. It’s about documenting your learning journey, recording your insights, and reflecting on your challenges.

This is where a game dev journal can be invaluable. Keep a record of what you’ve learned, what you’ve tried, and what problems you’ve encountered. Note down your solutions, your discoveries, and your “aha!” moments. It can be as simple as a text file where you paste code snippets, or as organized as a database with dedicated fields for different aspects of your development process.

Indie developers often share their game development progress in the form of “devlogs” on platforms like YouTube, Twitter, or personal blogs. These devlogs not only keep players updated on the game’s progress but also serve as a record of the developer’s creative process. They are a great source of inspiration and knowledge for other developers.

Document your tutorial learning process

Tracking your progress and journaling helps you to better understand the choices that you make and is an excellent way to document your work to help other developers. A game development journal helps you structure your learning, track experiments, and solidify your understanding. It becomes a valuable resource for future reference and a testament to your growth as a developer.
