Procedural Content Generation for Unity Game Development

By: Ryan Watkins

Overview of this book

Procedural Content Generation is a process by which game content is developed using computer algorithms, rather than through the manual efforts of game developers. This book teaches readers how to develop algorithms for procedural generation that they can use in their own games. These concepts are put into practice using C# and Unity is used as the game development engine. This book provides the fundamentals of learning and continued learning using PCG. You'll discover the theory of PCG and the mighty Pseudo Random Number Generator. Random numbers such as die rolls and card drafting provide the chance factor that makes games fun and supplies spontaneity. This book also takes you through the full development of a 2D game. Starting with level generation, you'll learn how PCG can make the game environment for you. You'll move into item generation and learn the different techniques to procedurally create game items. Thereafter, you'll be guided through the more abstract PCG areas such as scaling difficulty to the player and even generating music! The book helps you set up systems within your games where algorithms create computationally generated levels, art assets, quests, stories, characters, and weapons; these can substantially reduce the burden of manually creating every aspect of the game. Finally, you'll get to try out your new PCG skills on 3D terrain generation.

DungeonManager


Our dungeon generator class will be called DungeonManager. The class will create the data the dungeon is made of and pass it to the BoardManager class to be built on screen. First, we need to create the C# script. Go to the Scripts folder and create a new C# script called DungeonManager.cs.

DungeonManager is a fairly large class, so we will view it in sections. Open up the DungeonManager for editing. You can see the first section of DungeonManager in Code Snip 4.1:

1 using UnityEngine;
2 using System;
3 using System.Collections.Generic;
4 using Random = UnityEngine.Random;

6 public enum TileType {
7   essential, random, empty
8 }

10 public class DungeonManager : MonoBehaviour {

We are going to need a list, a dictionary, and some PRNs for our Dungeon class. Lines 2-4 will enable these things for our use. Lines 6-8 introduces a global enumeration that we will use to keep track of our path types. Then, Line 10 leads us into the DungeonManager definition, starting with a helper...
