C++ Game Development - Many Ways to Kill an Orc (or a Hero)

on YouTube ↗51m

" summary

Compares concrete implementations: virtual-inheritance polymorphism, template-based interfaces, C++20 Concepts for intent and std::variant visitor-based dispatch, with working code and slides on the CppCon repo. Measures object sizes and run times (example numbers show a virtual-class baseline around ~500µs vs ~300µs with variant in one experiment), notes compile-time and extensibility tradeoffs, and demonstrates playable examples that compile and run; conclusion: trade-offs matter — size, speed, compile cost, and ease of adding new types.
