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.
