CS50 2D - Lecture 4 - Super Mario Bros.

Modeling 2D virtual worlds requires integrating tile maps, camera translation, and state-driven entity behavior. Super Mario Bros. serves as a foundational model for these systems, illustrating how to represent game space through grid-based tile maps and simulate movement using `love.graphics.translate`. Character animation relies on frame-based sprite sheet indexing, while state machines manage complex behaviors like walking, jumping, and falling. Procedural level generation enhances replayability by algorithmically placing tiles, toppers, and chasms, rather than relying on manual design. Efficient collision detection shifts from broad AABB checks to targeted point-to-tile mapping, allowing the engine to process only relevant surrounding tiles. Game objects, such as interactive blocks and power-ups, function as distinct entities that trigger specific callbacks upon collision, providing a robust framework for building interactive, dynamic environments.
