Entitas - The Entity Component System Framework for C# and Unity

Entitas is a super fast Entity Component System Framework (ECS) specifically made for C# and Unity. Internal caching and blazing fast component access makes it second to none. Several design decisions have been made to work optimal in a garbage collected environment and to go easy on the garbage collector. Entitas comes with an optional code generator which radically reduces the amount of code you have to write and makes your code read like well written prose.

First glimpse

The optional code generator lets you write code that is super fast, safe and literally screams its intent.

public static Entity CreateRedGem(this Pool pool, int x, int y) {
    return pool.CreateEntity()
               .IsGameBoardElement(true)
               .IsMovable(true)
               .AddPosition(x, y)
               .AddResource(Res.redGem)
               .IsInteractive(true);
}
var entities = pool.GetEntities(Matcher.AllOf(Matcher.Move, Matcher.Position));
foreach (var entity in entities) {
    var move = entity.move;
    var pos = entity.position;
    entity.ReplacePosition(pos.x, pos.y + move.speed);
}

Overview

Entitas is fast, light and gets rid of unnecessary complexity. There are less than a handful classes you have to know to rocket start your game or application:

  • Entity
  • Pool
  • Group
  • Entity Collector

Code Generator

The Code Generator generates classes and methods for you, so you can focus on getting the job done. It radically reduces the amount of code you have to write and improves readability by a huge magnitude. It makes your code less error-prone while ensuring best performance. I strongly recommend using it!

Unity integration

The optional Unity module integrates Entitas nicely into Unity and provides powerful editor extensions to inspect and debug pools, groups, entities, components and systems.
