Collisions are an integral part of game development. In this chapter, you will learn how Unreal Engine handles collisions and how to apply that knowledge. First, you will get a high-level technical overview of collisions and the various collision settings available in UE4. Then, you will be shown an example to demonstrate how these settings work. Finally, you will be shown how collisions can be applied in a real-world example, where colliding with an enemy causes damage to the player.
