Introduction

In the previous chapter, we learned about the remaining collision-related concepts in UE4, such as collision events, object types, physics simulation, and collision components. We learned how to have objects collide against one another, changing their responses to different collision channels, as well as how to create our own collision presets and spawn actors and use timers.

In this chapter, we will go into several UE4 utilities that will allow you to easily move logic from one project to another and to keep your project well structured and organized, which will make life much easier for you in the long run and also make it easier for other people in your team to understand your work and modify it in the future. Game development is a tremendously hard task and is rarely done individually, but rather in teams, so it's important to take these things into account when building your projects.

We will mainly be talking about Blueprint Function Libraries, Actor Components...
