ECS Basics

EntitasRedux is an entity-component-system or ECS framework for Unity. In this architecture, a developer's general workflow consists of:

• Defining one or more Components representing distinct pieces of data about an Entity representing an object in the ECS simulation.
• Executing code-generation using Genesis in the Unity Editor to create and/or extend the EntitasRedux framework for those Components.
• Implementing Systems that represent the stateless behaviour or mechanical logic of the simulation working across multiple entities.

In this way Systems are stateless executors of game logic while most of the game's data and state lies on the Components of Entities themselves; Entities are little more than a simple unique object whose state is entirely contained on its Components and does not contain any behaviour of their own other than that imparted by Systems.

Essentials

• Components: Data
• Entities: Simple Unique Objects
• Systems: Behavior/Mechanics/Logic
