Pong (with Lua) - CS50's Intro to Game Development

简介：

In this first lecture of CS50's Intro to Game Development, the instructor introduces the course and outlines the lecture topics. He explains the basics of Lua, the LÖVE2D framework, and game loops, then walks through the 2D coordinate system. The lecture covers the development of a simple Pong game, detailing updates such as texture filtering, rectangle and paddle updates, ball movement, class structure, FPS optimization, collision detection with AABB, scoring, state machine, victory conditions, audio integration using bfxr, and screen resizing.
