Physics and dynamics are fundamental components in creating realistic and immersive game worlds. Whether it's the way objects interact with each other, how characters move, or how environmental forces like wind and gravity influence gameplay, physics systems bring a sense of realism and depth to your game. This chapter will guide you through the essential elements of physics and dynamics, covering topics like rigid body dynamics, fluid simulations, and gravity manipulation, as well as more advanced concepts like destructible environments and force fields.
