In the previous blog post, Building Games in ECS with Entity Relationships, I talked about the benefits of treating relationships between entities as first class citizens in a game. In this new blog post I’ll dive deeper into one of those benefits, and the futuristic capabilities it could unlock. Sit…

What is Flecs? Flecs is an Entity Component System (FAQ) for C and C++ that helps with building games, simulations and more. The core features of Flecs are: Store data for millions of entities in data structures optimized for CPU cache efficiency and composition-first design Find entities for game systems with a high…

This is the first in a series of posts about how to build an Entity Component System. Each post will cover a different part of the design and turn it inside out, so that at the end of each post you will have enough information to implement one yourself. In…

Behavior in games is in many ways defined by the interaction between entities. …

This blog is about Entity Component Systems. If you’d like to learn more about ECS, see this FAQ: https://github.com/SanderMertens/ecs-faq I usually shy away from the “P word” in conversations about ECS. Whenever it is uttered all it seems to do is divide people into two camps, which is rarely a…

I blog-skipped v2.2, so there’s a lot to catch up on :-) First of all, Flecs is an Entity Component System (ECS). If you don’t know what an ECS is, check out the FAQ. Much has happened since the last update, and not all of it in code! The Flecs…

One of the key design goals of Flecs is to enable reusability. When we talk about reusability, it is often the reusability of code. While that is a big part of it, reusability of data is just as important, especially in games. …
