Hack-/ is an Entity Component System written in Haskell specifically for game development. At the moment it uses a fixed step game loop and is targeted at game servers.
Experimental! While the API is currently in a good place (2016-11-09) the performance and correctness of the code is currently being verified as the primary driving project Armored Bits is being refactored on top of it. It is not recommended to actually try to use this library in any way shape or form for the time being.
