Pikuma, Gustavo Pezzi | Fundamentals of 2D Game Engines with C++ SDL and Lua (2021) WEB-DL [EN / EN Sub]

Инструменты , которые вам понадобятся
C++ — мощный компилируемый язык
SDL2 — это библиотека для кроссплатформенного рендеринга и ввода.
GLM — это вспомогательная математическая библиотека.
Dear ImGui — это библиотека для создания пользовательского интерфейса для инструментов движка.
Sol — библиотека привязки для современного C++ и Lua.
Lua — быстрый и простой в использовании язык сценариев

Целевой аудиторией этого курса являются начинающие программисты, которые хотят больше узнать о том, как работает C++ в контексте разработки игр. Поэтому учащиеся должны уже уметь программировать и быть знакомы с основными понятиями программирования и логики. Вы должны уметь писать операторы if-else, циклы, функции и классы, используя простой ООП.
