CS50 2D - Lecture 0 - Pong

Building 2D games requires mastering the core game loop—processing input, updating game state, and rendering frames—to create the illusion of real-time movement. Lua and the Love2D framework provide a lightweight, flexible environment for implementing these fundamentals, as demonstrated by the step-by-step development of Pong. This classic game acts as a microcosm for 2D development, incorporating essential mechanics like axis-aligned bounding box (AABB) collision detection, state machine management, and coordinate systems. Beyond technical implementation, achieving a cohesive aesthetic through pixel-perfect scaling and intentional font selection elevates simple shapes into immersive experiences. These foundational skills, including handling delta time for frame-rate independence and managing game states, provide the necessary building blocks for scaling from simple prototypes to complex, commercial-grade projects.
