A small and easy C++ Entity-Component-System (ECS) library

ecs

A simple C++11 Entity-Component-System library.

Entity-Component-System

Entity-component-system (ECS) is a software architecture pattern based on the concept of Composition over Inheritance and Data-Driven Programming techniques. As such, it is a paradigm orthogonal to Object Oriented Programming.

• An Entity represents an object, but does not contain any data by its own, nor any logic. It is only defined as an aggregation of Components, processed by associated Systems.
• A Component is a data structure that maintain a sub-state of an entity. The state of any Entity can be described by a few standard Components.
• A System is a program runing logic and updating data on any Entity holding a certain set of Components. Systems run repeteadly on all corresponding Entities.

Goals

Build an efficient, small, simple and easy to use framework, written in modern C++11 but compatible with widespread compilers (Visual Studio 2010 and GCC 4.6). Provide full Doxygen documentation, full test coverage and a few samples to show how to use it.

Requirements

Developements and tests are done under the following OSs:

• Debian 7
• Ubuntu 12.10
• Windows XP/7/8 And following IDEs/Compilers
• GCC 4.7.2
• GCC 4.6.3 with Travis-CI
• Visual Studio Express 2010/2013 for testing compatibility purpose

### Continuous Integration

This project is continuously tested under Ubuntu Linux with the gcc and clang compilers using the Travis CI community service with the above CMake building and testing procedure.

Detailed results can be seen online: https://travis-ci.org/SRombauts/ecs
