Gameplay Guide

Basic Gameplay Concepts

These pages will introduce you to key Unreal terms. To add new types of gameplay objects, you will generally create a new class. A class is a template, or collection of rules, for your new object, so that you can create as many copies as you need, each containing properties and behavior that you set in the template.
