Unreal Engine Physics Essentials

By: Devin Sherry, Vladimir Alyamkin, Katax Emperore

Overview of this book

This book gives readers practical insight into the mathematical and physics principles necessary to properly implement physics within Unreal Engine 4. Discover how to manipulate physics within Unreal Engine 4 by learning basic real-world mathematical and physics concepts that assist in the implementation of physics-based objects in your game world. Then, you'll be introduced to PhAT (Physics Asset Tool) within Unreal Engine 4 to learn more about developing game physics objects for your game world. Next, dive into Unreal Engine 4’s collision generation, physical materials, blueprints, constraints, and more to get hands-on experience with the tools provided by Epic to create real-world physics in Unreal Engine 4. Lastly, you will create a working Vehicle Blueprint that uses all the concepts covered in this book, as well as covering advanced physics-based topics.

What are constraints?


Constraints are basic physical actors in Unreal Engine 4. Imagine that physical rules need something to be presented with, such as a tool, switch, calculator, or container. It's called physic actor, and physic actors that are responsible for simulating the physical behavior between two objects are known as physics constraint actor.

It works in a similar way to a minicomputer. You can connect two inputs to it, and it calculates how these two should play with the physical rules in the game. Finally, it applies the changes to the object as real-time processing during the game play.
