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
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.
