Learn to build an Entity Component System with Data Oriented Hierarchies for efficient game development

intermediate Published 25 Jun 2026
Action Steps
  1. Design an Entity Component System to manage game data in contiguous arrays
  2. Implement a data-oriented hierarchy to store and access game data efficiently
  3. Use caching and buffering to minimize data transfer and optimize performance
  4. Apply this approach to a specific game development project to test its effectiveness
  5. Optimize the system for frequent hierarchy changes using techniques like delta encoding or incremental updates
Who Needs to Know This

Game developers and programmers can benefit from this approach to optimize their code for better performance and scalability. It's particularly useful for teams working on complex games with frequently changing hierarchies.

Full Article

Data Oriented Design is the practice of building code that's optimized for the hardware it runs on. Entity Component Systems help writing DOD-friendly code by laying out otherwise allocation-heavy game data in contiguous arrays. A challenge in gamedev however is that lots of game data is stored and accessed as hierarchies that change frequently, which makes them notoriously difficult to stor
