C++ libraries

• EnTT EnTT is a header-only, tiny and easy to use library for game programming and much more written in modern C++. Among others, it’s used in Minecraft by Mojang, the ArcGIS Runtime SDKs by Esri and the amazing Ragdoll Autodesk Maya plugin.
  It’s mainly known for its entity-component-system (ECS) model. However, it offers also many other things useful during development, from flexible tools for managing signals to an integrated reflection system and so on.
  EnTT is also a production-ready, fully documented and a battle-tested library with a 100% coverage. Among others, it’s currently used in Minecraft by Mojang and the ArcGIS Runtime SDK by Esri.
