Chapter 4. Physics Objects
Physics objects are actors that can move, collide, and otherwise behave according to a physically accurate simulation, which is performed by the PhysX physics engine. This engine is integrated into Unreal Engine 3 and is responsible for all physical simulations—often called dynamic simulations—that take place during gameplay. Physics objects in Unreal are typically rigid bodies, or a series of rigid bodies attached to one another through the use of constraints. In this chapter, we explain what rigid bodies and constraints are as well as how they are used.
