DynaMix: A New Take on Polymorphism
summary
A C++ library that composes objects from runtime mixins added/removed at runtime and exposes unicast and multicast messages with message priorities and global mutation rules. It ships MIT-licensed, has been used in multiple games (Earthrise, Blitz Brigade, War Planet Online), and demos show adding health bars and hot-swappable plugins without restarting. Message dispatch is slower than a virtual call but comparable to or slightly faster than std::function; mutations are relatively slow and there is measurable memory overhead for many unique types.
