Unreal Engine Physics Essentials

Chapter 3. Collision

In this chapter, we will analyze collision in Unreal Engine 4, what it is, the different types of collision that exist in the engine, how to use it, and how to apply it to both static meshes and blueprints. To start with, we will first take an overview look of the different collisions that exist in Unreal Engine 4, but we will also cover the following topics:

• Simple versus complex collision
• Generating simple collision
• Creating complex and custom collision hulls
• Collision interactions
• Custom object and trace channels
• In-depth collision presets

For the purposes of this chapter, we will continue to work with Unreal Engine 4 using the Unreal_PhyProject that we created in the first chapter.
