Implementation of a component-based entity system in modern C++
summary
Implements a small but complete entity component system in modern C++ using C++14, SFML for visuals and a GitHub repo with code; components are plain data, logic runs in implicit systems via compile-time bitset signatures and per-component vectors (one array per component). Builds a particle demo that reaches around 50k entities on a laptop, shows create/kill with a refresh reorder algorithm, and adds planned handles for stable references; code compiles and the demo runs at high frame rates.
