Concord

Concord is a feature complete library that allows you to use the Entity - Component - System (ECS) model to write and organize your Lua code.

Concord puts a lot of effort on being easy to use and provide a great developer experience, while trying to be competitive in performance with alternative libraries.

Installation

Download this repository and add the concord folder to your project. Then import it:

local Concord = require("path.to.concord")

Note

The file imported should be concord/init.lua. Some Lua runtimes will allow you to require concord, but others will need concord.init.

Documentation

Start with Getting Started. It covers Worlds, Components, Entities, Filters, Systems, and Events.

Guides

• Custom Pools — using a different data structure than the default Pool list
• Pool Flushing and Timing — when Filters update, and how that interacts with Events

API reference is generated with LDoc and published on the GitHub page.
