Chapter 5. Physics Damping, Friction, and Physics Bodies

In this chapter, we will take a deeper look at Physics Bodies in Unreal Engine 4 and analyze how the engine uses physics properties, such as Angular Damping and Linear Friction to simulate real-world physics in our game. To start with, we will examine what Physics Bodies are. We will also look at some of the detailed properties available to these assets. In addition, we will discuss the following topics:

  • Angular and linear friction
  • Physical materials – an overview
  • Physics damping

For the purposes of this chapter, we will continue to work with Unreal Engine 4 and the Unreal_PhyProject that we created in Chapter 1, Math and Physics Primer in Unreal Engine. Let's begin by discussing Physics Bodies ...
