Vectors and Intersections for Game Development

Game physics and character movement feel magical, but they are built on fundamental mathematical principles. Understanding how vectors and intersections work is the key to creating responsive, realistic gameplay. This text-only course guides you through the foundational math of game development, helping you transition from guessing coordinates to writing precise movement, collision, and trajectory logic. You will learn to: - Understand core vector operations including addition, subtraction, scaling, and normalization - Apply dot and cross products to calculate angles, directions, and field-of-view mechanics - Resolve line, circle, and box intersections for accurate collision detection - Implement raycasting concepts to detect player sightlines and projectile paths - Translate mathematical formulas into clean, readable game code patterns - Practice spatial reasoning and coordinate system transformations used in modern engines You will start with basic coordinate geometry and vector definitions before moving step-by-step into intersection algorithms and practical game-physics applications. This course is designed specifically for beginner game developers and programmers who want to strengthen their math skills, with no advanced mathematical background required.
