Game Architecture

1. Introduction

Game architecture is the underlying structure that defines how a game is organized, including how components interact with each other. A well-structured game architecture can improve maintainability, scalability, and performance.

2. Core Concepts

• Game Loop
• Entity-Component System (ECS)
• Rendering Pipeline
• Scene Management

Game Loop

The game loop is the central part of any game architecture. It repeatedly executes game logic, updates the game state, and renders graphics.

while (gameRunning) {
    processInput();
    updateGameLogic();
    renderGraphics();
}
        

Entity-Component System (ECS)

ECS is a design pattern that promotes composition over inheritance. It allows for greater flexibility in defining game objects.

class Entity {
    // Unique identifier
    int id;
}

class Component {
    // Base class for components
}

class System {
    // Logic that processes entities with specific components
}
        

3. Game Design Patterns

1. Singleton Pattern
2. Observer Pattern
3. State Pattern
4. Command Pattern

4. Best Practices

• Keep code modular and reusable.
• Use version control to manage changes.
• Document your architecture for future reference.
• Test components individually before integration.
