A simple Entity Component System
This ECS is in no way attempting to be the most performant ECS there is available. It's just been a fun exercise to make my own and understand where the pitfalls in performance are. If you're looking for a performant ECS packed full of features then please check out things like EnTT.
I've made a video series on writing this ECS as part of a larger game engine series. If you're interested you can check out the "Let's write an ECS" playlist here: https://www.youtube.com/playlist?list=PLMClevbUJi9DsmIuij4RzjJ_kUyrQufEs
I'm also lacking in documentation and code quality, again this was purely a fun exercise and not meant for showcasing the best ECS.
To build you'll need to update the submodules. You should the be able to just use regular CMake calls after that.
