🚀 Basic Game Engine Learning Project

Building a Game Engine From Scratch using Modern C++ and OpenGL

---

---

📖 About The Project

This project is a beginner-friendly game engine built completely from scratch using C++.

The main purpose of this engine is to deeply understand how real game engines work internally instead of relying entirely on existing engines like Unreal or Unity.

The project focuses on:

• Engine architecture
• Rendering pipelines
• Memory handling
• Input systems
• ECS architecture
• Resource management
• Performance optimization
• Low-level game programming concepts

---

🎯 Learning Goals

This project exists to help learn and practice:

✅ Modern C++ ✅ Real-world engine architecture ✅ Rendering systems ✅ Memory management ✅ Performance optimization ✅ Game loops and timing ✅ Engine modularity ✅ Graphics programming fundamentals

---

🧠 Why Build a Game Engine?

Building a game engine teaches concepts that normal gameplay programming often hides.

It helps understand:

• How rendering actually works
• How memory is managed
• How engines organize systems internally
• How performance optimization matters
• How low-level systems interact together

---

📚 Learning Philosophy

Instead of using a ready-made engine, this project focuses on:

“Learn by building everything yourself.”

Every system is built step-by-step to gain deeper understanding of engine programming.

---

🚀 Future Plans

• ECS implementation
• Audio system
• Physics integration
• Scene serialization
• Editor tools
• Lua scripting
• 3D rendering
• Multithreading

📌 Notes

This project is not intended to compete with professional engines.

The goal is purely:

• Learning
• Experimentation
• Understanding engine internals
• Improving C++ skills
