EnTT

EnTT is a header-only, tiny and easy to use entity-component system (and much more) written in modern C++ and even used by Mojang in Minecraft. A long time ago, the sole entity-component system was part of the project. After a while the codebase has grown and more and more classes have become part of the repository. Consider it a work in progress. The whole API is also fully documented in-code for those who are brave enough to read it. Currently, EnTT is tested on Linux, Microsoft Windows and OS X. It has proven to work also on both Android and iOS. Most likely it will not be problematic on other systems as well, but has not been sufficiently tested so far.
