Exploring Game Engines for Development

Apr 13, 2025

Game Engines: An Overview

Introduction

  • Game engines frequently mentioned in game trailers and tech demonstrations.
  • Unreal Engine 4 graphics as an example of modern engine capabilities.
  • Discussion on the role of game engines in game development.

What is a Game Engine?

  • Framework for Game Development:

    • Simplified into three core areas: Graphics, Audio, and Logic.
    • Modern engines include additional frameworks for physics, AI, networking, optimization, etc.
  • Framework Benefits:

    • Historical context: Early games were made from scratch, requiring manual management of game objects and memory.
    • Engines provide tools and structures common to all games, preventing the need to "reinvent the wheel".

Evolution and Use of Game Engines

  • Old-School vs Modern:
    • Older games couldn’t afford the memory overhead of complex systems.
    • 3D game demand led to the widespread use of third-party engines to manage growing complexities.
    • In-house engines vs third-party engines trade-off.

Examples of Game Engines

  • Game Maker:

    • Simple enough for beginners; used to make basic games without writing code.
    • Limitations due to rigid structure but allows for creativity.
    • Example project: "To the Moon".
  • Unreal Engine 4:

    • Professional-level tool, free to use.
    • Supports complex 3D environments and advanced effects.
    • Features a Blueprint system for game development without code.
    • Source code accessible to subscribers for deep customization.
  • Unity:

    • Known for both subpar and excellent titles.
    • Free and simple, supports languages like C# and JavaScript.
    • Large community with plenty of tutorials and assets available.
    • Criticized for "shovelware" due to low entry barriers.

Getting Started with Game Development

  • All mentioned engines have free versions available for download.
  • Encouragement to explore game development through tutorials.

Making Your Own Game Engine

  • Upcoming tutorials on creating a game engine from scratch in C++.
  • Community projects and contributions, welcoming all skill levels.

Conclusion

  • Encouragement for all to try game development regardless of experience.
  • Invitation to participate in community projects and follow upcoming tutorials.
