Entity–component–system (ECS) is a software architectural pattern mostly used in video game development for the representation of game world objects. An ECS comprises entities composed from components of data, with systems which operate on the components.

Apr 12, 2025 · Frameworks often enable Entity Component Systems, and the term "ECS" is frequently used to illustrate a specific design pattern implementation. An ECS consists of the following elements: It has unique identifiers known as entities. It contains plain datatypes without behavior known as components.

Nov 21, 2017 · This article is about an Entity-Component-System (ECS) implementation coded in C++. An ECS is a design pattern mostly encountered in game development. It greatly improves the overall game architecture's flexibility and maintainability.

Instead of using inheritance for behavior reuse, as we've seen in the example, the Entity-Component-System (or short, ECS) pattern combines different strategies: It favors composition over inheritance, separation of concerns, and follows a very data-oriented approach.

Nov 22, 2017 · In this article I want to talk about the Entity-Component-System (ECS). It is a design pattern – mostly encountered in video games – which allows you great flexibility in designing your overall software architecture.

Jan 16, 2022 · In this multi-part series we’ll build the Entity Component System used in Mach engine in the Zig programming language from first principles (asking what an ECS is and walking through what problems it solves) all the way to writing an implementation in a low-level programming language.

Nov 9, 2023 · Entity Component System (ECS) is a design pattern originally invented for structuring game engine architectures. Unlike the “traditional” Object-Oriented paradigm, ECS separates game objects into three primary elements: entities, components, and systems.

Feb 12, 2025 · Entity Component System (ECS) is a software architectural pattern primarily used in the field of Video Game Development to represent game world objects. This blog explores the Entity Component System, outlining its core elements, advantages, drawbacks and more. So read on and expand your prospect as a Game Developer!

Aug 13, 2024 · Entity-Component–System (ECS) is an architectural pattern. This pattern is widely used in game application development. ECS follows the composition over the inheritance principle, which offers better flexibility and helps you to identify entities where all objects in a game's scene are considered an entity.

Jan 5, 2019 · The entity component system (ECS) design pattern is surrounded by an aura of contradictions. It is not new at all, yet it is still often perceived as a fancy new thing by game programming newbies or developers who for some reason just didn't learn about it earlier.
