Physics Programmer A game's physics programmer is dedicated to developing the physics a game will employ. Typically, a game will only simulate a few aspects of real-world physics. For example, a space game may need simulated gravity, but would not have any need for simulating water viscosity. Based on system designs, computing power, and the restrictions of the game engine, physics programmers write the code that governs the natural laws of a video game. The physics engine is intended to simulate effects like gravity in the virtual environment, but this is only an approximation of what we experience in the real world. A number of physics elements must be worked into the virtual world, depending on the style and demands of the game. The programmer is tasked with implementing code for collision detection, the effect produced in games when two objects interact—for instance, two cars locking bumpers, or a character’s ability to pick up a weapon. In addition, the physics programmer writes code for particle systems that control explosions, moving water, smoke, and snow.
