Exploiting Physics

In the early days of 3D gaming, developers programmed basic walking mechanics based on real-world physics. But players quickly discovered that by moving the mouse sideways while jumping in mid-air, a math error in the engine's vector calculations allowed them to accelerate indefinitely. This unintentional glitch, known as bunny hopping and strafe jumping, transformed slow-paced shooters like Quake into high-speed adrenaline sports. This book explores the fascinating history of movement mechanics in video games. It dissects the actual source code flaws that created these iconic exploits and how developers went from trying to patch them out to fully embracing them as high-skill mechanics. The narrative highlights the intense subculture of movement players who pushed digital physics to the breaking point. Dive into the technical brilliance behind gaming's most famous unintended features. Discover how a simple rounding error in the collision detection software accidentally laid the high-speed foundation for the modern competitive esports industry.
