Game Development in 2D: Mastering Vector Math and Touch Interactions

Dive into the essentials of 2D game programming with a focus on vector mathematics and touch responsiveness. Explore angled vector calculations and learn to apply velocity in your game physics, creating smooth interactions with touch events like TouchUp. Understand the nuances of broad phase collision detection using spatial grids and master camera techniques, including translation, scaling, and the projection matrix. You'll also discover advanced features like texture atlases, sprite batching, and animated sprite sheets to enhance your game's performance and visuals.
