Unreal Engine Physics Essentials

Chapter 2. Physics Asset Tool

PhAT stands for Physics Asset Tool. Imagine you drop a dice. Based on the reality of the physical rules in the world we live, the dice drops differently on wood, stone, glass, and carpet. The same can be said for glass, plastic ball, and enemy body (more complex). Using PhAT, you will learn how to simulate reality based on the physical rules that exist in the game world. This is kind of animated, but with more logics and tools.

In this chapter, you will first learn about the most important items in PhAT and then use them in a practical example.

Navigating to PhAT

Before we start working in Unreal Editor, we will need to have a project to work with. Perform the following steps:

  1. First, open Unreal Editor by clicking on the Launch button from Unreal Engine Launcher.
  2. Start a new project from the Project browser by selecting the New Project tab. Then, select Third Person and make sure that With Starter Content is selected. Give the project a name (phat_test). Once you are finished, click on Create Project.

After everything comes up on your screen, in Content Browser, locate the ThirdPersonBP folder and click on the Character folder. Find ThirdPersonSkelMesh and then right-click on the list and select Create | Physics Asset, as shown in the following screenshot. Then, click on Ok in the New Asset window.

Note

ThirdPersonSkelMesh can be found by the name SK_Mannequin in the newer version of Unreal Engine 4.

Now, if everything works fine, you will find your selected mesh in Physics Asset Tool or PhAT. This kind of editor allows you to put...

Summary

Now, you can use PhAT to make your character move and reflect, which is similar to the real world. Keep in mind that working on PhAT is presenting the game story over the character behavior. It is an art because all the details and time that you spend here are directly monitored and tried by the player (perhaps hundreds of times while playing the game). It is good practice to imagine a character with some special behaviors, like movement, impact on other objects like walls, guns or fire, in real world; and then, try to recreate that behavior using Unreal Engine. It is a physical simulation with many details which we have gone through in this chapter. As a game designer, more practice will guarantee high quality results.

You can import the rigged mesh from the 3D software and apply the same physic assets to them. The mesh should be rigged in a proper way, which is similar to what we used as default in this chapter. Try the online sources by searching Unreal Engine 4 PhAT on YouTube...

Key benefits

  • Use the Physics Asset Tool within Unreal Engine 4 to develop game physics objects for your game world
  • Explore the Collision mechanics within Unreal Engine 4 to create advanced, real-world physics
  • A step-by-step guide to implementing the Physics concepts involved in Unreal Engine 4 to create a working Vehicle Blueprint

Description

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.

Who is this book for?

This book is intended for beginner to intermediate users of Epic Games' Unreal Engine 4 who want to learn more about how to implement physics within their game-world. No matter what your knowledge base of Unreal Engine 4 is, this book contains valuable information on blueprint scripting, collision generation, materials, and the Physical Asset Tool (PhAT) for all users to create better games.

What you will learn

  • Get to know basic to intermediate topics in mathematics and physics
  • Create assets using the Physics Asset Tool (PhAT) in Unreal Engine 4
  • Develop Collision Hulls, which are necessary to take advantage of Unreal Engine 4's physics and collision events
  • Use constraints to create advanced physics-based assets for your game-world
  • Working knowledge of physics bodies, physics damping, and friction within Unreal Engine 4
  • Develop physical materials to recreate real-world friction for substances such as glass and ice
  • Create a working vehicle blueprint from scratch using assets provided by Unreal Engine 4
  • Implement multiple physical elements and materials to simulate complex behavior over the objects in game

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
